New Users Test.... Just would like to what people think.

[ZulzanFlux]

Hello....

This is my first time posting here and using SpeedGuides TCP/IP Analyzer. I would like to know what all this means.

I'm running WIndows 2003 Server, with a D-Link DI-704 router,
I ran both spybot and adaware before posting.

I am currently uncertain of the advertised caps down/up speed ratings for Shaw Cable. I Live in Manitoba, Canada.

If there is any way to make my connection speed any better, I'd more than appreciative.

TCP options string = 020405b40103030301010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000


I also tried this test I found on another post:
That isn't a speed test try this ftp://ftp1.optonline.net/pub/test64
donwload it about halfway and let us know the resaults.

My average download speed was 390 KB/Sec

Thanks.

whoa, you need to lower that RWIN, Shaw's caps are kinda ambiguous, but usually 3000/384 are a good estimate, download Cablenut (http://www.cablenut.com) and try these values:

DefaultReceiveWindow = 384000
DefaultSendWindow = 49152
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
Priority Boost = 0
SmallBufferSize = 12800
TransmitWorker = 32
FastSendDatagramThreshhold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceives = 0
GlobalMaxTcpWindowSize = 75920
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAttacks = 3
TcpMaxHalfOpen = 100
TcpMaxHalfOpenRetired = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 75920
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTimeToLive = 64
DefaultUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

c/o Mnosteele:

FOR FASTER WEB PAGE LOADING:

This tweak will help web pages load faster, it has no real effect on download speeds, just helps your pc look up websites faster thereby speeding up how fast the page loads and making web-surfing more enjoyable.

Navigate to this registry entry and change the following settings:

For XP & 2K
HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ Tcpip\ ServiceProvider

DnsPriority = 1
HostsPriority = 1
LocalPriority = 1
NetbtPriority = 1

To change the value right mouse click on the value and select modify and enter the values above once you have done all of them reboot to take effect and see how fast your pages load.

Make SURE you follow these important tips as well:

1. Open Internet Explorer and select Tools - Internet Options - under the General tab in the Temporary Internet files section select the Settings button.

Select "Every visit to the page" and set the amount of disk space to use: to no more than 80MB. Now select the Connections tab and select LAN Settings make sure EVERYTHING there is unchecked and select OK.

2. For IE6 ONLY - select the Privacy tab and choose Advanced check the box "Override automatic cookie handling" and for First-party Cookies - Accept, Third-party Cookies - Block and check "Always allow session cookies. Now NO MORE SPYWARE COOKIES.

3. Another thing to do about once a week if you modem is on 24/7 is to power cycle your modem, just completely disconnect power from it for atleast 15 seconds and then power it back on.

4. Set your temporary internet files to 80mb and delete them regularly.

5. DSL users may want to check out the DSL Wiring Guide for possibly increasing your DSL speed.

6. By default Windows 2K & XP cache everything in the DNS cache service, both correct and faulty DNS lookups. To increase performance by eliminating the caching of faulty DNS lookups, change the following values from whatever their original values are to zero.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servi
ces\Dnscache\Parameters]
"NegativeCacheTime"=dword:00000000
"NetFailureCacheTime"=dword:00000000
"NegativeSOACacheTime"=dword:00000000

7. Always connect your modem via ethernet (Network Interface Card) instead of USB, ethernet is faster and much more stable. Also ALWAYS make sure you have the latest drivers for your NIC from the manufacturer NOT Microsoft, alot of times the drivers from the manufacturer have advanced settings that help optimize the performance of your NIC that the native Microsoft drivers don't have.

8. Scan for spyware weekly with Ad Aware & SpyBot.

9. Make sure you have the latest drivers for your NIC from the manufacturer. If you are using a router make sure you have the latest firmware.

10. For 2K & XP - Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

After I used your suggestion for cablenut and a reboot this what I got

I was over at broadbandreports.com and was looking at the scores people using shawcable.net and was amazed that they could get speeds that where this fast 7802/454.

How in world can they achieve this?

The best I can do is 2818 / 449

[j79zlr]

shaw is wierd, I've seen speeds of between 2000-8000kbps and their site doesn't really say. The setting I gave you and what the TCP analyzer are saying aren't the same. Did you use Cablenut or use the DefaultReceiveWindow in the optimizer?

[ZulzanFlux]

I used Cablenut like you said and used every setting you put up.

originally I only used SG Optimizer.

[j79zlr]

OK, when please double check them again, your settings are different then what I gave you ;)

After entering them, make sure to hit 'Save To Registry' and then reboot. Please post back another analyzer after your done.

[j79zlr]

somehow it is not giving you the right settings. Uninstall the Optimizer first, then reenter the settings I gave you.

[mnosteele52]

ZulzanFlux take your time and put in the settings EXACTLY as j79zlr has posted them for you and then select "save to registry" and reboot then repost your settings.

Only use CableNut, pay close attention to these settings:

DefaultReceiveWindow = 384000
GlobalMaxTcpWindowSize = 75920
TcpWindowSize = 75920


:cool:

[ZulzanFlux]

After I deleted all the cablenut settings I rebooted the machine. Re-entered all of the info that j79zlr gave. I mean exactly the was he wrote it down.
If I could show you a print screen I would.


This what I got... It seems to be the same.

2003-08-14 10:47:59 EST: 2809 / 474
Your download speed : 2809033 bps, or 2809 kbps.
A 342.8 KB/sec transfer rate.
Your upload speed : 474158 bps, or 474 kbps.
Seems like broadband .. above the 1mbit barrier!

[ZulzanFlux]

If you look at my first post.... My results for below where 390 KB/Sec

That isn't a speed test try this ftp://ftp1.optonline.net/pub/test64
donwload it about halfway and let us know the resaults.

Now with the new tweaks that where given to me my download speed at 50% where around 520KB/Sec

Now that's quite the jump in performance.
