[Catalyst] DProf

[Octavian Rasnita]

Hi,

I have tried to see which of the modules of my Catalyst application take so 
much time, because at certain moments the processor is occupied 99.9%, then 
goes down to 12%, then again at 99.9% and so on.

I've used the module Apache::DProf in httpd.conf, and the results are below, 
but I don't know what can I do to solve the problem and to make the 
application consume less processor time.

The processor of the machine is an Intel Core 2 Duo at 2.4 GHz, and the 
computer has 8 GB of RAM, and the application isn't very big. It has just 
130 templates and 21 controller modules that have aproximately 400 KB.

It worked fine until I added Catalyst::Plugin::I18N and I've translated the 
interface into 3 languages, but I don't know if this is the cause, or how 
could I solve it in other way if I still want to have the interface in more 
languages.

Isn't Catalyst able to handle big applications? Or what could I be doing 
wrong?

Thank you. Here is the DProf result:
