Author: Emmanuel Gravel Date: Subject: Funny network performance problem
I recently purchased a dual-speed full-duplex switch (TrendWare brand,
got it relatively cheap). Decided to check the speed by transfering
large files (more than 100MB). Linux to Windows, I get 2.4-2.8 MB/s.
Windows to Linux, I get 0.8 MB/s at best. I've tried transfering only
from one to the other, then full duplex transfers, and I get the same
numbers.
Now, to start with, 2.8MB/s is better than what I'd get at 10Mb/s but
it's not quite as fast as I expected it to be. But the other side of the
equation is pretty bad. Both cables between the computers and the switch
are the same, they're fully molded, factory quality, I got them when I
purchased my first (10Mb/s) hub. Network cards are Kingston KNE100TX on
the Windows system, and Intel EtherExpress 100's for the Linux system
(two, the Linux system is my firewall). Obviously all transfers of those
sizes are done on the internal IP's only, and using an FTP client on
Windows (push/pull).
Does anyone know how I could trace the issue and resolve it?
