I am a new Perl developer and just found out about the great benefits of
mod_perl.
I had a Perl cgi script that ran fine. It consisted of 1 main.pl file
and multiple subroutines that each had their own file in a directory
called libs (it is in the same directory as main.pl). When I got
mod_perl
://perl.apache.org/docs/1.0/guide/ for
your own good ;)

Great feedback, many thanks. But as always, one problem becomes another !
I've compiled + installed Apache-DB
I've compiled + installed DProf-19990108
I've added this to my httpd.conf:

I've added this to my modperl.conf (called by httpd.conf):

Thankyou, but I have read the documentation.
Nothing gets written to a rootdir/dprof directory, not even an empty file
when the scripts are run.
You aren't doing it wrong. Next step is to run the script and usually it
helps to read the docs :)

sorry, you should have told this :0)
Could be write permissions?
Can you profile a normal perl script?
You aren't doing it

When you call the script, do you get segfaults in the error log?
Make sure that you do the DProf stuff, including Apache::DB-init(),
before you load any of your

I've been profiling my MySQL driven Mod_Perl website by adding debug
messages throughout the code which relays what time has elapsed since the
script was invoked (using Time::HiRes)
Now the script is pretty whizzy, serving up complete pages in circa 0.010
seconds.
I got to wondering how those
Have you tried using Apache::DProf? Using this is a lot easier than
trying to add tons of debug messages. If you haven't used it or the
regular DProf, it does what your doing automatically. It generates a
file of data that you run 'dprofpp' on and you can get a list of the top
10 or so most

No, for benchmarking nearly-empty subroutines run times. Since the error

machine and if your sub didn't fit into one CPU timeslice, but the other
did, the relative difference can

and subroutines from package on one tree, get called by programs in the
other tree.
The mod_perl documentation suggests that by using the Apache::PerlVINC
module it is possible to load
the appropriate module based upon the name of the virtual host used.

Hi!
I should migrate Perl-CGIs to mod_perl for performance reasons.
We use many subroutines in our CGIs, which read and write
global (my-defined) variables. Our plain subroutines are not nested,
but they are when the mod_perl wrapper is put around them at execution time.
In this special case
for such subroutines?
A good programming practice is to never let
a sub {} depend nor use any variables which are not explicitly
passed to it. If severel subs should have some kind of globally
used structures to work with, explicitly pass it by reference
to each sub. If you follow that basic rule, you
I'm seconding Ime's suggestion, and adding one piece, you don't have
to use anonymous subroutines for everything..., that would be.., well,
a big pain. Named subroutines where EVERYTHING it uses is passed in
via references. Also it's return values are sent back via reference
as well
