lists:
$233 Athlon MP 2800
...x2=$466
$403 Dual MP server (rack)
$170 1GB DDR memory
...x4=$680
just an idea.

Just a few notes:
Pliny crashes roughly once a month. This must stop.
Not only are the outage periods annoying, but every
crash risks
corrupting the database. Hardware problems have been
vaguely suspected,
but we've never really had the chance to swap pieces
out until it stops
crashing.
At this point I would tend to suggest that we:
* replace pliny as the database server with a
slightly beefier machine
(eg, the Altus 130 or 140, with the max of 4 gig
ram)
* take the old hard drive _out_ of pliny and set it
aside, as it's been
suspected of being a problem
* reassign pliny as the new web server front end
* reassign larousse as the backup server; it could
hold both a
replicated database and take over web server duties
in a crash emergency
by taking over the other machine's IP address
The present larousse is overloaded (typical load
average around 8-10
during daytime US, or up to 30 if some ass decides
to spider the site
for every printable page), and a lot of pliny's CPU
is taken by its
additional web duties (pushing load to around 4).
More RAM for the database should help it.
More CPU for the web server would definitely help
it.
More RAM for the web server should help it once we
start making more use
of in-memory caching, which should decrease load on
the database (and
decrease the amount of stuff that it has to lock,
leading to faster
response times on reads while other operations are
running).
