You won't see any real performance improvement, but it certainly
would be an improvement to your code.
No offense, but I've never seen a 350k module that didn't need
to be broken into SEVERAL other modules for
readability/maintainability reasons.
I'm over generalizing here and not taking into account
bloated/memory hogging modules, but files/packages/modules
are cheap to use and create and should be broken up for reasons
other than performance.
I just looked over one of the largest mod_perl apps I help
maintain, there are 67 modules and only one of them is over
20k in size.
