Expensiveness in embperl subs

[Neeme Vool <ne...@codewiser.com>]

Hi!

Which is more expensive (memory and processing time)

I want to use some functions on two pages, but one, say A is very rarely
executed, B is very heavily. Is it better to have embperl subs in B and use
them in A throught Execute with import=>1 or put subs into C and import to
both?
Or write instead real perl module and return only processing result for
[+Mymodule::sub( args )+] ?

There is no (real) difference in memory usage

For 1.3 having subs in B will be faster, for 2.0 ist doesn't matter (as long
as the Execute import =>1 is in a [! !] block). You can get the same result
with 1.3 as having the subs in B (and as in 2.0) when you set the
optKeepSourceInMemory for C (but reloading when C changes may not work
correctly)

Basicly, haveing many [+ +] blocks is a little smaller then doing everything
with one [+ +] block, but having literal HTML is faster then a [+ +] block,
so basicly it depends on how your output isstructured. From the executing
time it doesn't make a difference if you call a Embperl sub or a Perl sub.
