Slowness on the wikis from pliny right now is probably
due to either
Apache problems or database locking issues. I'm open to suggestions.
Could we see the output of netstat, particularly the number of closing
connections. If there are very many, look into Lingerd:
http://www.iagora.com/about/software/lingerd/
From their website:
"Lingerd is a daemon
(service) designed to take over the job of
properly closing network connections from an http server like Apache.
Because of some technical complications in the way TCP/IP and HTTP
work, each Apache process currently wastes a lot of time "lingering" on
client connections, after the page has been generated and sent. Lingerd
takes over this job, leaving the Apache process immediately free to
handle a new connection. As a result, Lingerd makes it possible to
serve the same load using considerably fewer Apache processes. This
translates into a reduced load on the server."
Here's some interesting reading on tuning Apache:

Hope it helps,
