[Catalyst] server memory usage

[John M. Dlugosz]

Looking at the server's processes, I see three of script/myapp_fastcgi.pl, which I suppose 
co-inside with the Apache configuration option where I said to start 3 fastcgi processes 
to handle this app.

WebMin tells me "size", which can't be the actual load of server RAM needed since it 
doesn't add up with the total usage.

Some basics here... is Apache/fastcgi/Catalyst smart enough to load the app and get it 
running to the point where it is ready to start handling requests, and THEN fork it?  The 
Perl runtime and all the loaded modules can certainly be shared!  Do I need more advanced 
configuration or app tuning to maximize this ability?

How can I tell, through WebMin or command-line tools via ssh, how much memory is really 
being used by my apps?

Thanks for any pointers!
