"We have just learned that it's important to preload the modules
and scripts at the server startup. It turns out that it's not
enough for some modules and you have to prerun their initialization
code to get more memory pages shared. Basically you will find an
information about specific modules in their respective manpages. I
will present a few examples of widely used modules where the code
can be initialized."
"... You probably know already that under mod_perl you should
use the Apache::DBI module to get the connection persistence,
unless you open a separate connection for each user -- in this case
you should not use this module. Apache::DBI automatically loads DBI
and overrides some of its methods, so you should continue coding
like there is only a DBI module."
