Want to tweak my connection

[derparson]

I been reading site for 4 days now and i must say ....you guys rock!

Well anyway i attempted to tweak my connect and actually ended up with a slower connection. So i thought i would start from the beginning and perhaps get some of your expert advice :)

To begin with i use roadrunner. I also play alot of online gaming, RTCW.

1.5mbs down
384kbs up

os XP pro

TCP properties for IP =
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)


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 = 54 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Is SG's Optimizer installed, if not follow directions in help thread below:)

Welcome to speedguide derparson:)

Where are you from, in most places RR has caps of 2000/384

That is what mine are:)

[derparson]

indiana :) thanks

I downloaded SG's Optimizer installed and followed directions. Not any noticable improvements.

I was reading where i can set my ethernet card to one of these settings.

autosense
100BaseTX
100BaseTX Full_Duplex
10BaseT
10BaseT Full_Duplex

Right now mine is on autosense

10BaseT if it's not behind a router set it to that. to do that you got my computer control panel network network card click configure.
:D

Download Cablenut from my signature and try the following settings:

DefaultReceiveWindow = 256000
DefaultSendWindow = 49152
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
IgnorePushBitOnReceives = 0
GlobalMaxTcpWindowSize = 52560 or 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfOpenRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 52560 or 64240
MaxConnectionsPer1_0Server = 40
MaxConnectionsPerServer = 20
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

Also add the following entry to your registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic
es\AFD\Parameters

Add the parameter BufferMultiplier and give it a value of 400 hexidecimal which will make it 1024.
