OK. So now i'm concerned too. I have almost an identical setup for Zope (RedHat 6.2, Dual 867Mhz PIIs with 1GB ram) - majority of the content in ZODB. I am running two zope instances, albiet without ZEO, and my performance is timid to say the least - I've always suspected it's image heavy pages and excessive use of javascript (don't ask). But the call profiler reports 1/2 second generation times for pages on average, the pages take 4-5 seconds to load in the browser over a T1. Can anyone point me to how to setup apache to cache zope pages? I am using proxy passing (mod_rewrite) currently, but I suspect it's not caching. -jim ----- Original Message ----- From: "Magnus Heino" <magnus.heino@pleon.sigma.se> To: <Zope@zope.org> Sent: Monday, October 28, 2002 10:25 AM Subject: Re: [Zope] performance issues
What's needed is a way to *prevent* python from using more than one processor, so you can run one (or more) instances of Zope per processor and bind them to that processor. This depends on the OS. IIRC Solaris can do this, but Linux out-of-the-box cannot.
Linux actually does have a processor dispatch mask. To the best of my knowledge it is only used for interrupt handers that need to be CPU bound. Linux provides no facility to set this mask, although I have seen patches that will allow you to set it via /proc.
Redhat Advanced Server seems to have support for this...? http://www.redhat.com/software/advancedserver/technical/ -- /Magnus _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
