[Zope] zope performance issues

[Stefan H. Holek]

Trevor,

That's not how it works. If you think in terms of Apache processes == 
Zope threads, you are wrong :). In fact, the recommended number of 
threads depends highly on your application. If you have a 
(well-dimensioned and busy) SQL backend, using more that 4 (the 
default) worker threads *may* increase performance. If your app is CPU 
bound, *reducing* the number of worker threads may give you better 
results.

At the end of the day it is multi-processing (not multi-threading) that 
makes Zope fly (*coughs*).

Stefan
