I have just tested an out-of box apache 1.3.9 with a page of ~18kb
and an out-of-box zope 2.0.1 server with 1.2 kb zope opening page
on an IBM NetFinity 5500 M20, dual Pentium III/500MHz with the 
following results:

Changing the number of threads did not change a thing and top showed only 
3-4 threads actually getting work. The cpu usage was ~= 1.0.

Are the numbers terribly wrong ?
