Argh, this is a step in the wrong direction...
Thanks to Justin I got my geometry problems squared away. Software
re-installed fine, but the ethernet card on a good day with a tailwind is
getting maybe a kilobyte or so per second.
vmstat -i and vmstat don't show any unusual activity, and adjacent boxes
running BSD/OS and the same cards/hardware zip along like crazy.
It's especially noticeable when editing, as even with vi, it only draws
about half the screen at a time, then a pause, then a draw, then a pause.
I just finished ftp'ing a 600kilobyte file, and it took 400 seconds at a
grand total of 1.5Kbps.
The transfer is extremely slow in both directions, both gets and puts.
This would explain why it took something like 12 hours to install via
FTP, I thought it was wcarchive, but it doesn't look like it.
Let's see, fresh SNAP install, on a P5-90/PCI (triton), 3c509, I think
a Cirrus PCI video, and a 2940 SCSI, with 4 Conner drives on it.
I have run BSD/OS on this config, modulo a BusLogic rather than Adaptec,
and it hauls butt.
(I should also mention that modulo networking, everything from the
console screams).
