Is there anything important to consider when increasing the thread count above 7 as outlined here in 24.4.2/3: http://docs.zope.org/zope2/zope2book/MaintainingZope.html
I have tried to 10 but encounter problems with number of open file descriptions on Centos 6. Cheers Rich

Reducing the number of threads (down to 1) and having multiple app-servers is usually the way to go instead of increasing the number of threads.

Oh, and if you have some kind of health-checks polling your instances, it may make sense (I have no evidence, just a hunch) to add one more thread to keep that stuff from getting in your way (e.g. munin.zope checks, haproxy heath polling with OPTIONS request, etc).
OTOH, maybe the tiny requests like the haproxy checks don't really block for long enough to matter, even if they run every few seconds.
