No, maybe I wasn't clear. I didn't get 1000 hits/sec, what I said was that I measured the time a page needs to be loaded after the program had made 1000 hits to Zope (so that it would be a bit a loaded). Also I don't know if this is caused by TIME_WAIT because when I do a netstat I don't see a lot of connections on TIME_WAIT Actually I think it has to do with the threads library (see my other mail on that) > > There could be other reasons, of course, but this will overshadow the > others.
