I finally got FreeBSD 4.3-RELEASE installed on my Thinkpad 380XD, but I'm
having some problems.
The 380XD is a 233MHz Pentium II, and it has 64 meg of RAM. But it seems
very sluggish. Every time I type a command to the shell, it appears to
take a *very* long time (sometimes on the order of 3 or 4 seconds) before
anything actually happens. During this time, I can hear the disk seeking
around. The sequence goes something like:
% cat /etc/motd [just for instance]
[audible disk chugging]
[file finally starts to print out about 3 or 4 seconds later]
Once a program has actually started, it seems to proceed without delays,
*unless* it later has to do any disk I/O (in which case it stalls when it
hits the disk). It almost seems like the system is retrying bad disk
reads, but no retries are being logged.
My dinky little Dell Latitude XPi (133 MHz Pentium, 24 meg RAM) seems
quite speedy in comparison - it has no such delays, and its response
'feels' much faster.
This is very puzzling - I'd welcome any clues as to where to start looking
for this problem ....
