Duh, well yes that's a start ... But how would I make sure I do this for all threads? Running this once would load/cache the objects only in the thread in ran in. That's the hard part I think :) J.F. -----Original Message----- From: Jean Jordaan [mailto:jean@upfrontsystems.co.za] Sent: May 28, 2004 8:18 AM To: Jean-Francois.Doyon@CCRS.NRCan.gc.ca Cc: zope@zope.org Subject: Re: [Zope] Help!

While I've got your ear ... Is it possible to prefetch objects in the threads' object cache? So that instead of loading objects on demand, I could force the loading at start-up?

Iterate over them. Eg. for p in context.Catalog(meta_type="whatever"): p.getObject() They should now all be in memory.
