Re: ModPerl::RegistryLoader

Hi Jiri,

i am not sure what you are trying to do with ModPerl::RegistryLoader,
but what me helped to improve performance was :

1. Preload almost every library on startup:
PerlPostConfigRequire /xyz/startup.pl (

---------
use Apache2::RequestRec();
use Apache2::RequestIO();
use Apache2::RequestUtil();
use Apache2::ServerRec();
use Apache2::ServerUtil();
use Apache2::Connection();
use Apache2::Log();
use Apache2::Request();
use APR::Table();
#... and so on
----------
2. reused db connection over requests

3. using mmap cache for Data that comes from db

4. last but not least use HTTP cache Protocol with mod_cache

All together hundred of projects with hundreds of simultaneous requests 
are possible on only one server.
regards Keywan
