As for the mysql issue, I suspect the bottleneck is purely a MySQL thing if Zope doesn't behave that way all the time. Note that even though you may be running Zope in threaded mode, the MySQL client library for python (which we did not write and do not support) is not thread safe, so you should NOT run Zope 2.0 with more than one thread if you want to use MySQL. Someone may want to patch the MySQLDA so that the whole thing is wrapped in a lock, or serializes requests before the client library is entered. Either way, given that no one is paying us to do it, we probably won't.
Which database adapters are thread safe? I don't see this information anywhere on the web site, it'd be nice to know. :)
Chris is still evaluating this question. We'll let you know as soon as we know. On a similar note, there will be a handful of DAs that we support, all others will be continue to be unsupported, and probably unthreadsafe unless someone patched them up. (What inspires us to support a DA you ask? Answer: $$$) -Michel
