[Catalyst] Catalyst needing LOTS of RAM

[Neo [GC]]

Hello guys,

after fiddling around with Catalyst+DBIx starup time, here comes my next 
issue:

Is there some way to tune Catalyst to use less RAM? Is there even some 
kind of explanation for the really FAT memory footprint?

Currently, our project allocates 330MB RAM right after startup (with 
myproject_server.pl or fastcgi). Over the time this is getting worse; 
some month after the projects start it used about 80MB and we think with 
some additional controllers and stuff it will need over 500MB. I know 
there is some advent calendar entry about restartig the catalyst-process 
when it reaches a memory limit (what is good - our processes tend to 
grow up to 1GB), but this doesn't help at startup.
Is this normal behaviour?

The problem is, we use multiple instances of the application. So every 
customer has his own catalyst instance with own database and - of course 
- own fastcgi-process. Currently we are running it on a machine with 
16GB of RAM and will soon get to the physical and budgetary limits.
Is Catalyst just not intended for this kind of use (and more like "one 
server, one site") or is there some black magic we just haven't found yet?


Btw: Neither reducing the count of the DBIx-models nor disabling the 
debug-mode does have an impact on memory footprint.


Thanks and regards,
