I think most of the traffic comes from anonymous users browsing the
site. That traffic is most of the time served by squid unless the page
is not in the squids cache.

Any logged in people directly hit the apaches (that's why some people
complain that their wiki is slow while the others are fast, just cause
they are not logged on other wikis :p).


Tim Starling is working on a tool that dump static html pages (I have
seen the result with my local installation and it looks complete). So
eventually we could serve anonymous users an 'outdated' version of
pages, and refresh that once per day. The apaches will then only used
for logged users.

There is also ESI caching promised in squid 3 (although squid 3 might
never come out). It is able to cache only a part of a page (aka the
text) and mix it with dynamic content (customized toolbars, skin stuff).
That could boost our performances too but that's long term.

cheers,
