Not if your machine is cpu-bound. You need enough threads to keep your cpu busy, but any more than that means each one gets a smaller share of the cpu, and a smaller share of the memory.

The bloat is caused by a large squishdot site (20.000 comments) That will really benefit from 2.6 and a bigger cache, as seb suggested. Fewer threads means you can have a bigger per-thread cache, for the same total memory usage. -- Toby Dickenson http://www.geminidataloggers.com/people/tdickenson _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
