persianpower Posted January 16, 2005 Report Share Posted January 16, 2005 Hey,I have XP PROwith TELUS VELOCITY ADSL (always connected)Download cap = 150kb/sUpload cap = 64kb/sI usually hover around 40-100Kb/sec (usually closer to 40)Ive gone through all of the recommandations (i.e, uninstalled zone alarm, ran spy/virus checks, analyzer test, checked network and ie settings, added registry tweaks, unplugged modem, went inside lan properties, applied PPPOPE fix (spelling), etc etc etc...But still i experience a lag when surfing. Is anyone able to help me tweak my Cablenut settings to the max? Thanks MY CURRENT SETTINGS (analyzer results to follow)DefaultReceiveWindow =192000DefaultSendWindow = 65536DisableAddressSharing = 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 = 64240MaxFreeTcbs = 8000 MaxHashTableSize = 16384 MaxNormLookupMemory = 5000000 SackOpts = 1 SynAttackProtect = 1 Tcp1323Opts = 1TcpLogLevel = 1 TcpMaxDupAcks = 3 TcpMaxHalfOpen = 100 TcpMaxHalfOpenRetried = 80 TcpRecvSegmentSize = 1460 TcpSendSegmentSize = 1460 TcpTimedWaitDelay = 30 TcpUseRFC1122UrgentPointer = 0 TcpWindowSize =64240MaxConnectionsPer1_0Server = 20 MaxConnectionsPerServer = 10 DefaultTTL = 64 DisableUserTOSSetting = 0 TcpMaxDataRetransmissions = 6 DefaultTOSValue = 92HERE ARE TCP/IP ANALYZER resultsTCP options string = 020405b40103030201010402 MTU = 1500 MSS = 1460 Default Receive Window (RWIN) = 192000 RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)Unscaled Receive Window = 48000 For optimum performance, consider changing RWIN to 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)256960 (MSS x 44 * scale factor of 4)128480 (MSS x 44 * scale factor of 2) 64240 (MSS x 44) bandwidth * delay product (Note this is not a speed test):Your RcvWindow limits you to: 7680 kbps (960 KBytes/s) @ 200msYour RcvWindow limits you to: 3072 kbps (384 KBytes/s) @ 500ms MTU Discovery (RFC1191) = ON Time to live left = 53 hopsTTL value is ok.
