Hi,
We're having an "interesting" problem with a significant slowdown in
processing of some HTML::Template templates.
We are using:
- using H::T 2.8 and 2.9
- an house framework that feeds params from a CGI object to H::T
- CGI 2.81 and 3.15
- Perl 5.8.0 and 5.8.4
If the following conditions hold:
- template X is <TMPL_INCL>uded
- the parameter "region" is set (for <TMPL_LOOP NAME="REGION">)
then processing time for the template is approx 1 second longer.
However
- if either the TMPL_INCL or the TMPL_LOOPs are commented, processing
time is reduced
- the TMPL_INCL does *not* refer to the TMPL_LOOP, and neither does the
one template it in turn includes.
The DProf runs include the following (with some entries for BEGIN on
inhouse modules removed) :
--------------- without including TMPL_LOOP

10.4 0.300 0.256 28736 0.0000 0.0000 HTML::Template::param
e.g. the odd things include
- "HTML::Template::BEGIN" is called a large number of times. I don't
see that many BEGIN { } or 'use' blocks in the H::T code, nor do I
understand why they would be called because of a TMPL_INCL
- HTML::Template::LOOP::output takes proportionally much longer.
I'm sorry that this isn't a minimal test case - I'm working with our
HTML editor to try to identify what it is! But if anyone has any
suggestions on where to start trying to debug this, I'd be interested,
and grateful, to see what you suggest.
Regards,
Hakim (osfameron)
