[Zope] zope stops responding

[Jaroslav Lukesh]

Hi, I does not agree with You, because my servers runs with 20..150 threads, 
because lower number of threads makes for somebody infinity waiting and Zope 
under load responding very slow (with external database access). After 
increasing threads, response under load is more quickly and more paralel 
users should access to the web.

My experience is that increasing the number of threads past 4 does
absolutely nothing to assist performance.   Multi threads will help with
the occasional long running request, but if its more than occasional
then the thread list will eventually clog up no matter how many threads
you have (and the more threads you have, the more they fight over the
processor).  The server sounds beefy, but since Zope is only going to be
using one of those four cores, that might be deceptive.
