You can also have a look a SpeedPack to speed up TAL. See : http://psyco.sourceforge.net/ to download and install psyco And then see : http://sourceforge.net/project/showfiles.php?group_id=55262&package_id=10732 6 To only use TAL optimization, you change : PATCH_CMF = True To : PATCH_CMF = False in config.py This works fine on Zope 2.7.3 Pascal -----Message d'origine----- De : zope-bounces+pperegrina=lastminute.com@zope.org [mailto:zope-bounces+pperegrina=lastminute.com@zope.org]De la part de Chris Withers Envoyé : jeudi 20 janvier 2005 10:44 À : Robert Hill Cc : zope@zope.org Objet : Re: [Zope] TALInterpreter Performance Robert Hill wrote:

Hey all,

I just installed Zope Profiler to check out the performance of my pages and I noticed that I have a few bottlenecks on TALInterpreter calls that I'd like to clean up. The issue is that the per call time seems a bit high on some of these. Granted, I've got a lot more TAL statements in my page templates than I would like (eventually I will pull these out into scripts), but are these numbers unusually high?

It all depends how complex you page templates are. You need to find the slow/complicated bits and make them faster, if you're experiencing slow page load. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
