Differences in bandwidth on different PC's in LAN

[kevinnn]

Once again, I have a question and would like OC's opinion/input.

I have a home network with 2 PC's. PC1 is on win2k and PC2 is on winxppro. when i test PC2's bandwidth at

http://www.bandwidthplace.com/speedtest/index.php

i get 2.3 megabits per second. however, when i test on PC1's i get 1.3 megabits per second.

could there be a difference because of operating systems? or is the testplace inaccurate?

What does your network setup look like?
Have you ran a tweak test (http://www.dslreports.com/tweaks) on both boxes?

my network is just a 2port hub.

cable modem > router > computer 1: windows 2000

computer 2: windows xp pro

computer 2 has a better bandwidth. and what does that tweak test do?

The tweak test checks your system for certain parameters, mainly in you TCP stack that affect transfer or recieve speed. It does this by sending you a small bit of data and watching how long it took, how many retries, how small of chunks it needed to put it in, etc.

Based on that, you can use the Dr.TCP tool at that site to modify your settings to what it recommends. For speeds like you are describing, you probably have your settings way out of whack, or a damaged cable, or it's just a slow computer.

If the setup you said was that both computers were plugged into the router, then your network should be fairly equal on both boxes.
