Re: Diazo performance problem

With similar problem I've compiled xlst using diazocompiler 
(http://docs.diazo.org/en/latest/compiler.html) and made some tests 
using diazorun. In my case the problem was a complicated xpath condition 
and too huge xlst file.

Are you running zope in console or run mode, not foreground, right? In 
foreground the diazo to xlst compilation are not cached....
