[Zope] Surprising load test results?

[Pascal Peregrina]

Ok, so far, list feedback is:
+ WSGI test looks wrong
+ 100 concurrent threads looks a little heavy
+ results are not the same as Tres' ones

So, as soon as possible, we will try to make some more tests and will let
you know when the wiki page is updated.

Thanks a lot for the feedback so far.
