Jim,
What platform is this on? and is it a uni or multi-processor system.
I did a bit of studying a long time ago into performance of Solaris
with python:

not sure how relevant it is now, but if you are running on an old
solaris box there might be some hints there.

On a production Zope (2.7.6) running behind apache and connected to an
Oracle database, I'm finding that once a user requests a page which
runs a particularly slow sql (say up to 5 minutes), any other subsequent
requests seem to take the hit as well, and return very slowly.
I have 8 zserver threads and a ZODB pool size of 10. I'm fairly certain
I'm not maxing these out. So is this blocking effect just expected
behavior for zope? One point of note is that the requests passed from
apache all bear the remote ip of 127.0.0.1. Could zserver be throttling
the incoming requests due to their identical REMOTE_IP (or some other
apache configuration detail)? Is there anything else I should investigate?
