[Zope] TALInterpreter Performance

[Pascal Peregrina]

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 :

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

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,
