Saturating the server
I used the nice hammerhead tool (http://hammerhead.sourceforge.net) to
stress test the beta.wikipedia.com server. The tool lets you simulate
several simultaneous users repeatedly requesting pages from (or
posting to) the server.

I have my users request RecentChanges (33% of the time) and issue
searches (66% of the time). Here's the average response time of the
server:

1 user: 2 sec
5 users: 4 sec
10 users: 8 sec
20 users: 11 sec
100 users: 42 sec

These are only the times it took the server to respond; the actual
total time to complete a request is not as useful in my case because
of my limited bandwidth.
