Plone 4 out of the box is already one of the fastest content management systems around. And it’s still getting faster. Malthe Borch has cut a major new release of Chameleon that gives Plone another big speed bump with almost zero effort.
Chameleon is a lightning fast drop-in replacement for the Zope Page Template system that Plone (and other Python applications) use. By simply adding Chameleon to your Plone 4 buildout, you can immediately speed up your site by 20% or more, with zero code changes.
The homepage of a stock Plone 4.1rc3 instance yields 13.23 pages/sec on my laptop test environment. With Chameleon added to the buildout, it jumps to 15.94 pages/sec. That’s a 15% increase. Not too shabby! In the real world, where your page templates are doing considerably more work, you should see an even bigger boost.
Malthe’s been brewing this up for a while now, and it’s great to see it cross over into “ready for everyday production use.” Give it a try! Malthe’s taking bug reports if you run into any hiccups.
