eh, sorry for probably stating the obvious. you menationed in an earlier mail that you have good hardware. If this hardware is multi-cpu then I suggest that you use some tool (i.e. taskset on linux) to bind each zope python process to a single cpu. Threaded python applications does not work well in multi-cpu settings where there is a chance of a threaded python process being spread out over more than one CPU. I causes a, sometimes signinficant, performance loss. Just by binding the zope python processes to a single CPU (not necessarily the same, just make sure that any single python process is not spread over more than one CPU) you will notice a preformance increase. And like all the others said, Caching is you friend. Start by checking the ZODB cache numbers in the zope-conf file (too start simple). IIRC, the default is 5000 objects. Increase that to, say 50.000 or so (you mention that you have a busy site). Good luck. /dario -- -- ------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.
