I've been tring to track this performance problem down now for sometime 
without any luck.  I have been getting the following:

~745KB/S FTP transfers on an SGI box to a Linux server 

~210KB/S FTP transfers on a Pentium/75 w/ 3Com509b card running Novell's 
             Lan WorkPlace TCP/IP stack to the same Linux server

~750KB/S FTP transfers on the same Pentium hardware but running Linux 
             (slack:2.3 Kern: 1.2.10) to the same Linux server

Some people have told me that the reason for this is DOS's default TCP 
Window size of 2048 where Unix's is 8192.  I've tried to find where I can 
adjust this without avail.  Could somebody set me strait on this?

Here is my net.cfg file just in case:
