Better to use the Benchmark module for this. It looks like you only run
each one once. A few hundred iterations would give more stable results.

I'd wager a pint on this. We could make it a lightning talk at next

Hi,
When I was using TT, my program was able to serve 1.7 requests per second.
(tested with ab program - Apache Bench).
After using HTML::Template, the same program, but modified to be able to use
HTML::Template, was able to serve over 3 requests per second.
After using HTML::Template::Compiled

I have tried to learn more about caching in TT, but I could find only that I
could create cache, and nothing more. No tweaking

You should learn about caching. Tweaking the template caching settings

Just to reiterate - the difference in templating time is very likely
negligible when you factor in your application logic.
ie:
on my tests a HTML::Template file interpolated in .00x, while a
HTML::Template::JIT interpolated in .000y
but my application logic takes .025 to work
.25x

Populating the loop happens before running HTM

I'd second that..1500 seems too high for human consumption.
Anyway, for such large datasets you can try going XML/XSLT
way. XSLT transforms are VERY fast (use LibXSLT) - downside
being XSL is a super verbose and
.
Running it by a cache (cache=>1) seems to make the NEXT interation faster
though. But the first one is always slow.
