we are using Catalyst under mod_perl2. and every httpd is costing
130-200M. `top` shows:

is it normal under Catalyst+DBIx::Class+Template? or there is something
wrong?
What's your Catalyst App costs? Thanks.
I suppose that's a 'top' output; memory columns should be: virtual,
resident, shared.
memory usage is thus between 120 and 130 MB for each httpd instance
(e.g. 1360MB resident - 6M shared).
For example, on one of my servers I have vmware server running:
4615 root 5 -10 365m 307m 296m S 0 15.2 81:57.93 vmware-vmx
3905 root 5 -10 381m 304m 291m S 2 15.0 85:41.40 vmware-vmx
resident: 307MB, 296 of which are shared among the two processes.
If all those httpd processes run the same app I think they have should
have more shared memory.
You could probably check if you preload your app in your apache config file.
Something like:
<Perl>
use lib qw(/path/to/MyApp/lib);
</Perl>
PerlModule MyApp;
etc.

Just my 2 eurocents.
