[Dancer-users] questions about speed

today I found, that previous version of our project (hosting billing
system), written on perl, fastcgi and using CTPP as template engine
generates pages faster, then new version of this project, written with
dancer and ctpp and running with plackup/starman. The most part of the
code remains the same, but we add cache(*) and reduce the number of SQL
queries (this led to an increase of speed - we checked it).
So the question - where should I look for the problem?
The first idea - I know that HTML::CTPP2->new() takes a lot of time. It
is called in Dancer::Template::Ctpp2, which is `use base
so the question - is sub init() in this module runs only once when
starting the app, or on every query?
The second question - can this be because of plackup or starman? Where
should I look in this case?
ps: plackup -E production -s Starman --workers=4 -l bill.sock -a
One parallel query in all cases.
pps: (*) about our cache - just in-memory hash with already loaded data
from db, which returns already loaded data instead of making new query -
this can not lead to taking more time on requests. And, without this
cache, with the old code, it's just slower.
