Hmm, 10 hits per second doesnt really seem that fast to me - especially
given that here were no real bandwidth limitations in the test. That works
out to about a million hits a day.

With the concurrency level thing. Are you saying that in the first test, you
made 1000 requests, with 100 active at any given time, but then you made a
second test in which you made 1000 requests all at once, and the results
were that the server managed 10 hits per second on the more complicated
page, i.e. it took about 100 seconds for the server to process both tests.

What is ZEO? Z Enterprise Objects? I find no reference to ZEO anywhere on
the zope site, nor on the digicool site.
