Old hardware is certainly part of the problem. My 500mhz P3 doesn't go as fast as 1.3G P3 
or the AMD 3800 when doing network tests. Firewalls and firewall software also add to the 
overhead, along with other processes running in the background on the system. 

Another issue is Selective ACK responses and it should be set so that the system doesn't 
respond to every packet, time stamping should be turned off, too. Send and Receive window 
size (a buffer), is also a significant issue at higher speeds. OS/2 will adjust somewhat 
automatically, but it's better to have a larger buffer than a smaller one at these speeds, 
and there a calculator at DSLREPORTS based on speed and latency.

You can test what the settings are at DSLREPORTS (Broadbandreports) with the TWEAK 
Tool/Test. Use Free BSD as the OS when they ask, and it will give you some suggested 
settings and can tell what your TCPIP settings are. IT's suggested that you become 
'pingable' to use the test fully. Use the inetcfg command to fix the tcpip stack 
parameters.
