Hi,
I have a Solaris Workstation Ultra 1 170Mhz and a FreeBSD server Pentium
Pro 200Mhz, w/ 2940 SCSI and vx0 ethernet interface manually set to 100
Mbps, on a 100 Mbps LAN. Last week (maybe since upgrading 2.2.5 Stable
from december to 2.2.6 BETA, beginning of March) I have experenced bad
network performance between the two.
Here's an ftp transer of on huge file from Sun to Freebsd 2.2.6 BETA:
12621935 bytes sent in 1.3e+02 seconds (95 Kbytes/s)
Here's the same file ftp'd from the Sun machine to a 2.2.2-stable
pentium on the same LAN but running 10 mbps (we have a 100 mbps hub with
a downlink).
12621935 bytes sent in 13 seconds (9.6e+02 Kbytes/s)
Better... Really good, I'd say ;-)
Now, I try from 2.2.2 to 2.2.6 BETA:
12621935 bytes sent in 13.76 seconds (895.56 Kbytes/s)
Also quite alright.
So, what can this be? It happens on nfs, ftp, amanda, you name it, so it
seems like it's the tcp/ip or ethernet stuff somehow. This is beyond my
level.
One thing I'm supecting is that I don't use full duplex with the
ethernet card on the 2.2.6 server since this crashed the machine while
booting; I had to manually set it to half duples (simplex?). Haven't
tried resetting this, but I will as soon as I can take it down.

BTW, the huge file is m$ internet explorer for solaris, which throws me
out of my CDE session and kills all apps immediately each time I try it.
So much for commercial software ;-)
