I have also found that the catalog becomes very sluggish after a 'find and catalog' to catalog the 10,500 items. It takes 10 mins for the catalog to return with the 'catalog' tab listing the cataloged items. It takes a further 10 mins before the python process drops its usuage of the processor from 90-95% down to 0-10%. From this point on, the catalog takes 40-45 seconds to return found items using the site search form. Restarting Zope brings the catalog back to the 1.5-5 seconds I had achieved previously.
Using Zope 2.5.x ? This sounds like a typical symptom caused by excessive memory pressure on the ZODB object cache. You are probably seeing zope memory usage increase too?
2.6.x has a redesigned cache that shouldnt exhibit these problem.
Hmmm ... thanks to Toby for posting this. We are running a CMF site under Zope-2.5 and it's a slooooooooooow site :/ I just thought that it was the portal_catalog queries that caused this - which your posting indicated - and accepted that for the moment. I will try and switch the stuff to Zope-2.6 and see if it makes any improvements. Our use of memory on our Zope instance homes are BIG ! I hope to bring it down ... Greetings, Gitte Wange
