I tried many tweaks i know (thanks mnosteele52 tweaks and tips) but still cant get enough speed through my 7000/800 cable internet connection with Vif internet.
P3-733
512 Mb ram
XP home SP2
Linksys EtherFast Cable/Dsl 4-Port switch Router, Model no BEFSR41
Linksys 10/100 EtherFast PCI Adapter, model no LNE100TX
Motorola Cable Modem, model no SB5101
Test64 Speed Test results are not stable, start slowly from 400 ko/s, increase up to 700 ko/s but dont stay there, decrease to 300-500 ko/s, increase again, decrease..... and often ended in 400 ko/s
Speed test on http://www.stickdog.com : 4382/731
NiC card is set to 100TX Full Duplex. Other settings available are 100 BaseTx, 100BaseTxFull_Duplex, 10BaseT, 10BaseTFullDuplex, AutoSense. I use ISP DNS servers, it's faster this way for me.
BTW, i use mnosteele52 DNS cache fix for W2K/XP.

The NDT server has a 8192.0 KByte buffer which limits the throughput to 668.35 Mbps
Your PC/Workstation has a 876.0 KByte buffer which limits the throughput to 71.47 Mbps
The network based flow control limits the throughput to 14.42 Mbps
Client Data reports link is 'T1', Client Acks report link is 'T1'

Any suggestions to increase my speed ???
thanks
slow 7000/800 cable
do a few speed tests from here at speedguide and some at speedtest.net and even speakeasy.net and take a average..do a few in the morning and some at night.
Also this bothers me
also lower your RWIN some.. go to 256960 and make sure you run that slider at the top of Optimizer to the right some more beyond what your supposed to get.

your computer may be bottlenecking your connection.P3-733

About my RWIN, read this thread
Test result recommend.....
Reccomended RWINs: 64240, 128480, 256960, 513920
Tcp/ip analyser dont show it but I already use 128480. TcpOptimizer suggest 513920, i will try it and see.
I was with 4 Mbps adsl before, speed was ok with this P3-733. You are the first bother about my P3-733, 512 ram, you may be right, i dont know. Waiting for other opinion
thanks

Cause for slower upload speed may either be the presence of spyware or problem with the cable modem.piranha wrote:With 513920 last night, my dowload speed increase up to 6400 but my upload speed decrease to 3xx to 5xx kbps
This morning, it is ok with 128480, still not 90% of 7000.... Think i experienced cable slowdown at peaktime. Will test again
Anybody can comments my Argonne NDT server test !??
Scan for spyware and check modem log on power levels and SNR.

My cable modem is supposed to be ok according to search I made.
Sorry, english is not my first language, dont understand....
check modem log on power levels and SNR.
.... more details please. Explain how to do that
thanks
