[MTOS-dev] Memory Utilization Brainstorm

yes, sure! :)

I guess, that the complaints about memory utilization come from FastCGI 
users, right? Because, with this the memory is used even when there is no 
request at the moment.

AFAIK FastCGI starts each script as single application, and every script 
uses a lot of memory.
For this, it may be better to have only one script which dispatches to 
the wanted module.

Another solution is to use mod_perl (prefork!) and PerlHandlers and use 
each Perl module at startup -- then everything is shared. Such 
installation is usually used with a small frontend server for the static 
files and a fat backend for the dynamic. The is a more complicated setup 
and not for beginners, but mod_perl es very fast and flexible; if the SQL 
would be better, it could be used with superior performance for dynamic 
HTML generation in MT.


And a last brainstorming from me for now: 64 bit Perl uses much more 
memory then 32 bit; on 32 bit system it should be compiled without 64 bit 
support. And often the usage of Perl Malloc (USEMYMALLOC at compile time) 
results in lower memory consumption.
And Perl 5.10 should help too!
