[comp.unix.wizards] very slow tcp/ip under sco unix on a ps/2 ...

TRANLE@intellicorp.com (Minh Tran-Le) (04/14/91)

I am running SCO unix on a PS/2 with a 3COM ethernet board and I
have found that the TCP/IP is very slow.  FTP transfer file at around
2K/s.

Does anybody has that problem and know how to configure the 3COM board
or the unix kernel to get better performance ?

Thanks,
Minh Tran-Le.

There is a "known problem" with 3C503's on at least some of the faster
386 boxes, according to SCO. There is supposed to be a new driver that
will fix the problem available sometime in May. I don't know that this
applies to your PS/2 system, but it may.

I get FTP transfer rates into our 386 system of about .2K/s (yes I did
mean to say .2K/s) talking to Sun4's. Suprisingly the transfer rates
from Sun3's is reasonable (~35K/s).

If it is the same problem we've been having, there apparently isn't
anything that can be done other that wait for the new driver.
