Hello,
At this point I can't afford to get a Cisco or Intel switch. I can try to
replace the cards on a couple of machines and see what kind of increase that
will give. I been in environments where the Linksys rackmount models
performed decent, not great but not this bad either. If I could improve the
performance I will get 3com or Intel cards for the machines, and upgrade the
hub when $$ permits. I have spoken with people who get decent performance
from these cards, or are they the exception?
Thanks,
brian

no wonder, combine cheap network hardware with a cheap hub....
If you want real performance grab a Intel EtherExpress Pro card,
or a 3com card (as a second choice).
Ditch the hub, hubs only give you half duplex, basically you
can't transmit and send at the same time, this can kill performance,
pick up a switch, preferably a cisco or 3com, maybe even a Bay, but
I've heard bad things about Bay.
At home on my machines all Intel NICs i can get over 10MB/sec,
it's worth the extra 30-40$ for both speed and reliability.
(I have a Hawking 8port 100mbit switch, but I wouldn't recommend
it as it sometimes doens't comeback from a power cycles unless
I cycle it many times... blech, then again it was only 219$)
In production we use Intel cards almost exclusively along with
cisco switches.
