Apache is set to "MaxClients 50" Zope.conf has set "zserver-threads 5" and <zodb_db main> cache-size 500 pool-size 25 ... </zodb_db>
I will note that a cache-size of 500 is ridiculously low. (Even though old versions of Zope shipped configured like this!) It needs to be at least 5000. Frankly, 50000 wouldn't be bad for a large, busy site. To optimize your cache-size param, watch the ZODB read/write graph, and keep increasing the cache-size until (a) there's no more effect on reads or (b) you run into memory trouble. Of course, the optimization will slip a little as site usage patterns change. --jcc -- "Building Websites with Plone" http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com
