[OT] finding memory hungry bits of my code

Run 'ab' against your app to check that is indeed the case.
More info at http://modperlbook.org/html/14-2-6-Memory-Leakage.html

Use Apache status monitoring configuration for more detailed data:

Be aware that some of the memory usage shown per child is actually shared.
Make sure you're not loading any unnecessary modules into Apache.

Preload your Perl modules and DBIx::Class models in the Apache parent.  
The memory will become unshared over time so set MaxRequestsPerChild  
to force a reload.

You may also be able to save memory by running through FastCGI rather  
than Apache.
