Ping lowering and download increase.

[vital]

Pentium 3 866mhz
128MB RAM
GeForce2 MX 200 64mb PCI
Windows XP Professional

Comcast Cable Connection
1.5mbps/128kbs Advertised.
RCA Cable Modem, connected to SIMZ Ethernet card.
Microsoft Wireless Router

Cable shared with:

Another PC via Wireless base,
and an Xbox via cat5 cable.

Here are the results from my test:

TCP options string = 020405b40103030201010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 48 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

--------------------------------------------------------------

I get usually around 40 ping at best, and gain 20ms whenever another device is using my connection. My max download speed is about 150-kb/s, 180 at best, my friend gets 200-300 on the EXACT SAME CONNECTION.

I have cablenuts and everything, and appreciate any help.

Hi vital, first you MUST upgrade your RAM to atleast 256MB, 128 is not enough to run XP, if you can afford it go for even more, XP is a RAM hog. That being said use the following settings:

DefaultReceiveWindow = 192512
DefaultSendWindow = 16384
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 64000
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 64240
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

VERY IMPORTANT TO DO THE FOLLOWING

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&postid=643301#post643301)). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot (http://beam.to/spybotsd), anything checked in red is spyware and safe to remove.

7. Make sure you do the faster web page tweak in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&postid=643301#post643301).

:D ;) :cool:

yup yup in the process of getting 512 (max my mobo can handle) Thanks for all the settings, I'll try them out now!

[vital]

Heh I think I notice a decrease :X

[mnosteele52]

Try the OOL FTP test in my Help & Tips link and see how your speed is.

:) :D

[vital]

Stabilized at 180...


180 x 80 = 1440... my cap is 1500... not bad, i guess. but i noticed an increase in my latency for online games :/

[mnosteele52]

That's as good as your going to get for speed and there isn't allot you can do about latency, the AFD buffers I gave you should help as much as anything.

:D :cool:

[vital]

Is there some way that my friend uncapped then? Because he has the same service and gets 300kb/s download....

[mnosteele52]

Uncapping is illegal and he may have a different package than you, if your caps are 1500 down and you are averaging 1440 on the OOL FTP test enjoy it, most people would kill for that.:) :D
