Do you mean publisher threads, controlled with the Zope.py -T switch?
Increasing the number is right if you have some methods that are not
CPU-bound; maybe they load state from a db on another machine, or they
need perform alot of disk for each request.
If your methods are CPU-bound then increasing the number above the
default 4 will not help.
Also, each publisher thread gets its own copy of the objects cache. If
your site is memory-intensive then increasing the number of threads
can be conterproductive. Reducing the number of threads and increasing
the size of each thread's cache may be better.
