If you're running your scripts in Apache2::Registry, your scripts are
compiled on first go, and remain in memory subsequently.

When your script changes, the change should be detected, and
recompilation is automatic. IMHO this is a real time saver as
development goes.

do() is bad for speed optimisation as it's treated as a system call.
What you want instead is to modify your header.pl into a package, and
have your scripts call functions in the package. Minimise exec() calls
as well (ideally you should not use it at all).

Currently, each of the CGI scripts I have "sources" the same set of files (one for the header, another for the footer, etc). Per the above questions, I don't how the mod_perl processes work to keep everything in sync but I can only imagine that having each of my CGI scripts source the same files from disk has to be grossly inefficient.

In doing so, one possible constraint is that I'm also executing the same external scripts from several SHTML files. The CGI scripts call the filesystem based subroutines after initially sourcing them with 'do ./header.pl' whereas the SHTML files pass in a "go" argument to 'header.pl' to actually fire up the subroutine. This allows me to execute them immediately using SHTML 'exec' calls and 'on demand' from the CGI scripts.
