How to get MTU ?
Just use TCP/IP Analyzer http://www.speedguide.net/analyzer.php

How to get proper RWIN ? (TCP Receive Window)

RWIN DEPENDS ON FOLLOWING FACTORS

+ Bandwidth
+ Which country we are in
+ Which country we surf frequently

Formula
RWIN = BANDWIDTH (DOWNLOAD) * MAX.LATENCY /8

MAX.LATENCY : we should only assume worst latency to the country we surf to most often and stick with it.

+ We should make RWIN an EVEN multiple of MSS

+ Satellite or Wireless should use larger RWIN values because of the high latency

AFTER ALL THOSE CALCULATIONS, HERE IS A VERY ROUGH BREAKDOWN OF THE ANALYZER RECOMMENDED VALUES...

If MTU = 1500

513920 -- works for ~8 to ~30 Mbps
256960 -- 2 to 14 Mbps
128480 -- 1 to 5 Mbps
64240 -- works well up to ~2 Mbps.

If MTU = 1492

511104 -- works for ~8 to ~30 Mbps
255552 -- 2 to 14 Mbps
127776 -- 1 to 5 Mbps
63888 -- works well up to ~2 Mbps.

If MTU < 1472

+ Log into your modem/router and set MTU according to your connection type.
+ LEAVE RWIN BLANK and Uncheck Window Scaling
+ Use WinSockFix (http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml)
+ Update your modem's firmware to get higher MTU
+ Uninstall tweak programs like cfos Speed


If TCPOptimizer can not adjust your RWIN , try enter the value for DefaultReceiveWindow in Cablenut (http://www.softpedia.com/get/Tweak/Network-Tweak/CableNut.shtml)

Windows Scaling
Check Windows Scaling when RWIN > 65535

Constant Values:
Custom settings - check
Modify All Network Adapters - check
TTL - 64
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
Timestamps - uncheck
MaxConnectionsPerServer - 10
MaxConnectionsPer1_0Server - 20
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768

Host Resolution Priority

LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1

or (more prefer)

LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8


REMEMBER

+ Relocate your router and modem in proper place :
Relocate them to some place that are a few feet away from ALL other electrical devices, including apart from each other.Also, make sure you do not coil up any excess length of signal or power cables.

+ Scan for Spyware/malware:

We recommend


Ad-Aware 2008
Spybot Search & Destroy
SuperAntispyware

+ Disable unnecessary items :
Start > Run > type "msconfig" > StartUp tab > Uncheck unnecessary items

Start > Control Panel > Network Connection > Choose your Network > Uncheck "Client for Microsoft Networks”, “File and Printer sharing for Microsoft Network” , and “QoS Packet scheduler”.

Right click on My Computer > Properties > Advanced tab > Perfomance : Settings > Visual Effects tab > Check "Adjust for best performance" (check "Visual Styles on windows and buttons" and "Use drop shadows for icon labels on the desktop" if you want to keep WinXP theme).

+ Disable unnecessary services :
Run > Type "services.msc" > Disable "Application Layer Gateway Service", "Automatic Updates & Background Intelligent Transfer Service", "QoS RSVP" > Restart Win !!!


+ Using OpenDNS :
Start > Control Panel > Network Connection > Choose your Network > Properties > Internet Protocol (TCP/IP) > Properties > Use the following DNS server addresses => 208 67 222 222, 208 67 220 220.

+ Fake IP and Save Bandwidth with Toonel :
Toonel is an experiment in a technique for conserving network bandwidth. If you are paying a fee based on the amount of data you transfer (e.g. 3G/GPRS/DSL/CDMA) and have monthly download limit, or if you have narrowband connection (e.g. dialup modem) then you are most likely to appreciate the service toonel.net offers (http://toonel.net).

Note : It requires Java Environment (http://java.com/en/download/index.jsp)

Set the following proxy for Browser: 127.0.0.1 Port 8080

+ Internet Explorer : Tools > Internet Options > Connections > “LAN settings” > “ Use a proxy server for your LAN” > Address : 127.0.0.1 Port 8080.

+ Mozilla FireFox : Tools > Options > Advanced > Network > Connection > “Settings” > Manual Proxy Configuration > HTTP Proxy : 127.0.0.1 Port 8080.


+ FireFox Speed Hacks :

Speed Hacks

1. Pipelining: By default pipelining is disabled in Firefox. Usually when we visit a site the browser will make only one request to the server but while Pipelining is enabled it makes more than one request.It works like a download accelerator. You will notice a great change in speed while accessing sites in slow server.

In the filter bar type network.http.pipelining. You will be shown the result that matches your search. The first one will be network.http.pipelining itself with a boolean variable. Check the value, if its false double click and make it true

Next you will find an network.http.pipelining.maxrequests just below the previous line. Its an integer value with 4 as default. Change the value to 10, 20 or even 30. Test different values and see which one is optimum for your connection

2. Rendering Delay: Now create a new integer by right clicking anywhere and selecting Integer from New. Give the name as nglayout.initialpaint.delay and the integer value as 0. This specifies the amount of time the browser waits before rendering the page with information it got. You will find the page loading part by part but this is a useful hack as texts will be displayed first.
NOTE: If you get a lot of “Page not found” error after applying this, then try to increase the value from 0 to say 2 or 3.

Summary:

* Set network.http.pipelining to true
* Set network.http.proxy.pipelining to true
* Set network.http.pipelining.maxrequests to 20 or whatever value you like
* Create a new integer called nglayout.initialpaint.delay and give its value as 0

Optimize

Ever noticed of instances when Firefox’s CPU usage shoots up to 90% and the Memory usage shoots up to anywhere between 200 MB and 700 MB(this happens if you dare to open 200+ tabs like this gal tried )? Read on for some tips to improve the situation.

1. Excellent tips from Zolved (go to the site for detailed instructions)

Check your Extensions and Themes.
Check the Plug-ins.
Clear Download History.
Restart Firefox Periodically.
Assign Memory Cache on Firefox.
Release Memory when Firefox is minimized

2. Disable prefetch: Firefox has a nasty habit (sometimes this is useful) when you search in Google. It automatically loads the sites you are likely to visit like the first result. Disabling these can be a good idea for people with low-speed internet connection or low RAM. You can also disable this if you are bandwidth miser :P. To do this type in network.prefetch-next in the filter box and double click the value to turn it to false.

Summary

* Disable unwanted Extensions
* Disable unwanted Plug-ins.
* Clear Download History.
* Restart Firefox Periodically and don’t hibernate/sleep your computer while Firefox is running
* Set browser.cache.memory.enable to true, create a new integer named browser.cache.memory.capacity and give its value equal to 16 times your RAM capacity in MB (16 X your RAM size which is usually 256 or 512).
* Create a new boolean value named config.trim_on_minimize and set it to true
* Disable prefetch by toggling network.prefetch-next to false


FireFox Add-ons to save bandwidth and faster connection :

What would you say , Trogers ?

TCP Window size depends on bandwidth and max. latency and different countries or different continents will have different rules of thumb.

Default ToS value can be different. Suggested values that conform to both ToS and Diffserv standards are 80, 104 and 136 - http://www.speedguide.net/tcpoptimizer.php#advanced_qos

Some ISPs may not accept any value set to it other then zero.

Could You tell more , Trogers ?

[trogers]

Could You tell more , Trogers ?

The differences are due to differing max. latency - the time for a full sized packet to make the round trip. Thus it depends on where you are and which country you surf to most often.

If we use the US as the most surfed to place, then latency for users in East and South East Asia will be 450-550ms depending on time of day.

A user in the US will only face latency of 90-130ms. Thus TCP Window Size will be different for the same bandwidth.

How about latency for users in West ?

Sometimes , the TCP Window is left BLANK , Could you explain?

How about latency for users in West ?

How to deal with the DISTANCE PROPBLEM ?

Sometimes , the TCP Window is left BLANK , Could you explain?

All users face the same problem - a user in the US who frequents sites in Asia, or one in Australia to the UK, etc. Once you consider surfing to a different continent, latency will shoot up due not only to distance but also congestion along the international cable link.

There is nothing you can do at your end about latency along international links but to use a TCP Window sized appropriately.

TCP Window is left blank only in settings to try increasing MTU when TCP Analyzer reported some value that is not 1500, 1492 or 1480. When it is left blank with Window scaling unchecked, TCP Window will revert to default value 65535. If scaling is checked, the value will go above 10 million.

Trodgers have you tried the Opera browser? What do you think about it? As far as I have seen there is no need to tweak it as you have said that Fire Fox does need some.

[jasonb31]

Why cant my Dell with XP find “gpedit.msc” ? or gpedit.msc? Any Ideas?

Trodgers have you tried the Opera browser? What do you think about it? As far as I have seen there is no need to tweak it as you have said that Fire Fox does need some.

I use Opera when I do not need to see graphics. It has an easy switch mode.

Did you log into XP with Admin right's to run gpedit.msc?

[jasonb31]

Yes I am in the administor account. You dont like the Opera graphics? Is that what you are saying?

[trogers]

Yes I am in the administor account. You dont like the Opera graphics? Is that what you are saying?

Opera has no option to adjust graphic sizes unlike FireFox with add-on to zoom, fit to screen or reduce. I turn off graphic to enjoy page loading speed when surfing to reports and news sites.

[jasonb31]

I see!! Have any Ideas on the gpedit.msc thing? Maybe a Microsoft update killed that option? Just an Idea.

[jasonb31]

From what I have out so far is that you need to have XP Pro to do that. I have XP Home.

[Rollingstone]

I am using WinXP Pro and the Group Policy (gpedit.msc) has worked properly.

You can try "Regedit"

I believe gpedit.msc is only available in Windows Server 2003, Windows 2000, or Windows XP Professional and not XP Home.

Regedit pulls up all kinds of things. I dont have a clue what to do after pulling that up, Even if something can be done there.

What speed did you pay your ISP to give you?

I belive only philip can lock threads ,and maybe some of the mods. You'll have to talk to him about all that.

[DickDiver]

Hi thanks for the guide!

One big question bothers me. Browsing internet by wlan is fine but I have got a network HP printer connected by LAN wire and it prints damn slow.
It is a HP laserjet 2100TN with 8mb or 12mb. Anyway, I used TCPoptimizer and tuned 'only' my WLAN adapter for 1492 PPPOE and 16.000 advertised dl speed.
The question is, have I to adjust the LAN adapter to which my printer connects, too? Is it possible that the printer has problems with a MTU of 1492 or a much too high RWIN?

thanks
DD from Germany

[Rollingstone]

You can try LAN Tweaking : http://www.speedguide.net/read_articles.php?id=1607

[DickDiver]

Thank you Rollingstone

I will try that.

[Philip]

About those two settings:
Max Connections per Server
Max Connections per 1.0 Server

Many web servers do not support too many concurrent connections, setting to a number over 10 can cause problems loading some pages, or excessive repeat requests. I'd recommend setting both to 8 or 10 max.

[Rollingstone]

You cannot set QoS to zero with regedit.

I believe it is QoS: NonBestEffortLimit - 0 in TCP Optimizer !

[dlsayremn]

I was just wondering if you should have a warning about using Optimizer with Vista. Seems the consensus right now is to not use it with Vista.

[dlsayremn]

Someone may have already asked this, but shouldn't you have a cautionary note about using Optimizer and some of the Vista tweaks, esoecially the Autotuning ones, before seeking help? Seems the consensus right now is not to use Optimizer with Vista. Most of the posts I am seeing right now with Vista OS are because Optimizer was used and didn't work or the connection is worse.

I ran Optimizer on my Vista without any real problems last yesr.
Disabled Autotuning, ran Optimizer using custom settings and then enabled Autotuning.
Before doing this I was getting about 800/650 max from speedtedt.net

Previously I've tested the speed both off-peak and peak hour. I live in Malaysia. My friend who subscribed for 384kbps once had a chance to get some 500kbps. I couldn't pass the 3.6Mbps advertised to me. I think i have gained 2mbps or so, but for maybe once or twice. Other than that, it would be an annoying less than 1mbps, and even slower..let alone 3mbps. By the way, modem shows either HSDPA or 3G. Very unlikely to fall below that.

I've tried FullSpeed 3.0, then SC Net Speed Booster before removed them. I did use the SG TCP Optimizer 2.0.3 and followed the guidelines in this website, and forum. But then restored the default windows settings.

I'm very new to the internet , but I know, it's not even half of what i've paid for. Oh, by the way, the speedtest.net shows the wrong location (I don;t know..500 or 600 miles away) where I should be. I read somewhere that says my broadband Plan has a 5gb limitation cap each month.

In advance, I thank you sir. ;)

Then i've decided to rest on TCP Window: 256960.
Well, I don't know if thats the only pace i could get.
Speedtest.net shows somewhere in Sarawak or Sabah..while i stay in Johor.

Anyway, i really2 appreciate your help.

Then select "Apply Changes" and reboot to take effect

How to get MTU ?
Just use TCP/IP Analyzer http://www.speedguide.net/analyzer.php

How to get proper RWIN ? (TCP Receive Window)

RWIN DEPENDS ON FOLLOWING FACTORS

+ Bandwidth
+ Which country we are in
+ Which country we surf frequently

Formula


MAX.LATENCY : we should only assume worst latency to the country we surf to most often and stick with it.

+ We should make RWIN an EVEN multiple of MSS

+ Satellite or Wireless should use larger RWIN values because of the high latency

AFTER ALL THOSE CALCULATIONS, HERE IS A VERY ROUGH BREAKDOWN OF THE ANALYZER RECOMMENDED VALUES...

If MTU = 1500

513920 -- works for ~8 to ~30 Mbps
256960 -- 2 to 14 Mbps
128480 -- 1 to 5 Mbps
64240 -- works well up to ~2 Mbps.

If MTU = 1492

511104 -- works for ~8 to ~30 Mbps
255552 -- 2 to 14 Mbps
127776 -- 1 to 5 Mbps
63888 -- works well up to ~2 Mbps.

If MTU < 1472

+ Log into your modem/router and set MTU according to your connection type.
+ LEAVE RWIN BLANK and Uncheck Window Scaling
+ Use WinSockFix (http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml)
+ Update your modem's firmware to get higher MTU
+ Uninstall tweak programs like cfos Speed


If TCPOptimizer can not adjust your RWIN , try enter the value for DefaultReceiveWindow in Cablenut (http://www.softpedia.com/get/Tweak/Network-Tweak/CableNut.shtml)

Windows Scaling
Check Windows Scaling when RWIN > 65535

Constant Values:
Custom settings - check
Modify All Network Adapters - check
TTL - 64
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
Timestamps - uncheck
MaxConnectionsPerServer - 10
MaxConnectionsPer1_0Server - 20
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768

Host Resolution Priority

LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1

or (more prefer)

LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8


REMEMBER

+ Relocate your router and modem in proper place :
Relocate them to some place that are a few feet away from ALL other electrical devices, including apart from each other.Also, make sure you do not coil up any excess length of signal or power cables.

+ Scan for Spyware/malware:

We recommend



+ Disable unnecessary items :






+ Disable unnecessary services :



+ Using OpenDNS :


+ Fake IP and Save Bandwidth with Toonel :
Toonel is an experiment in a technique for conserving network bandwidth. If you are paying a fee based on the amount of data you transfer (e.g. 3G/GPRS/DSL/CDMA) and have monthly download limit, or if you have narrowband connection (e.g. dialup modem) then you are most likely to appreciate the service toonel.net offers (http://toonel.net).

Note : It requires Java Environment (http://java.com/en/download/index.jsp)

Set the following proxy for Browser: 127.0.0.1 Port 8080




+ FireFox Speed Hacks :

Speed Hacks

1. Pipelining: By default pipelining is disabled in Firefox. Usually when we visit a site the browser will make only one request to the server but while Pipelining is enabled it makes more than one request.It works like a download accelerator. You will notice a great change in speed while accessing sites in slow server.

In the filter bar type network.http.pipelining. You will be shown the result that matches your search. The first one will be network.http.pipelining itself with a boolean variable. Check the value, if its false double click and make it true

Next you will find an network.http.pipelining.maxrequests just below the previous line. Its an integer value with 4 as default. Change the value to 10, 20 or even 30. Test different values and see which one is optimum for your connection

2. Rendering Delay: Now create a new integer by right clicking anywhere and selecting Integer from New. Give the name as nglayout.initialpaint.delay and the integer value as 0. This specifies the amount of time the browser waits before rendering the page with information it got. You will find the page loading part by part but this is a useful hack as texts will be displayed first.
NOTE: If you get a lot of “Page not found” error after applying this, then try to increase the value from 0 to say 2 or 3.

Summary:

* Set network.http.pipelining to true
* Set network.http.proxy.pipelining to true
* Set network.http.pipelining.maxrequests to 20 or whatever value you like
* Create a new integer called nglayout.initialpaint.delay and give its value as 0

Optimize

Ever noticed of instances when Firefox’s CPU usage shoots up to 90% and the Memory usage shoots up to anywhere between 200 MB and 700 MB(this happens if you dare to open 200+ tabs like this gal tried )? Read on for some tips to improve the situation.

1. Excellent tips from Zolved (go to the site for detailed instructions)

Check your Extensions and Themes.
Check the Plug-ins.
Clear Download History.
Restart Firefox Periodically.
Assign Memory Cache on Firefox.
Release Memory when Firefox is minimized

2. Disable prefetch: Firefox has a nasty habit (sometimes this is useful) when you search in Google. It automatically loads the sites you are likely to visit like the first result. Disabling these can be a good idea for people with low-speed internet connection or low RAM. You can also disable this if you are bandwidth miser :P. To do this type in network.prefetch-next in the filter box and double click the value to turn it to false.

Summary

* Disable unwanted Extensions
* Disable unwanted Plug-ins.
* Clear Download History.
* Restart Firefox Periodically and don’t hibernate/sleep your computer while Firefox is running
* Set browser.cache.memory.enable to true, create a new integer named browser.cache.memory.capacity and give its value equal to 16 times your RAM capacity in MB (16 X your RAM size which is usually 256 or 512).
* Create a new boolean value named config.trim_on_minimize and set it to true
* Disable prefetch by toggling network.prefetch-next to false

[Rollingstone]

can i use the 65535 in lan request buffer size using the program tcp optimizer?

This value can be changed from 512 to 65535 bytes, more Buffer size -> more memory.

See this http://support.microsoft.com/default.aspx?scid=kb;en-us;Q320829
