Há promessas de grande ganho de velocidade [1] no carregamento dos
famigerados Zope Page Templates, chama-se Chameleon [3] e
possivelmente estará já no futuro Plone 3.2. 

Chameleon é um byte compiler para ZPT e Genshi. [2]
If you're a Python web developer and are interested in fast
templating, Chameleon might be of interest to you. Brought to you by
that crazy Austro-Danish duo Malthe Borch and Daniel Nouri, it's a
byte compiler that bakes HTML/XML templates into Python (byte) code.
Currently it has support for Zope Page Templates and Genshi. And it's
fast. Fricken fast. If I remember correctly, it doesn't achive the
same speeds as Google's Spitfire in all benchmarks, but it's in the
same league.
