Description: Using Devel::DProf on some of my programs produces output such as is found at Devel::Dprof is your friend, where most of the time is shown in MODULE::BEGIN. Does anyone know what that means when there are no BEGIN blocks in the module? Or does it just represent total calls to that module's subs? Answer: Why does Devel::DProf report so much time in BEGIN?
contributed by mikfire Without seeing your code, but having spent some
time with Devel::DProf myself, I will guess that
you are use'ing a number of modules.
If I remember correctly,
use foo;
is implemented as
BEGIN {
require foo;
import foo;
}
So, even though you are not explicitly using BEGIN
blocks, you are using them implicitly through
any use statements.
I would delve into the correct manpages and verify
my memory, but I am far from any machine with perl
installed on it :( And I have no ssh to get to
a machine I could so use.

contributed by Anonymous Monk After tirelessly searching for an answer to the same question (hence the search that turned up this page as a result), I ended up just tweaking my code until I got an answer. Several of my subroutines were missing from the DProf report until I removed all "use strict" and "use vars" lines from my code.
I really have no idea why this made a difference. Sure would be nice if it were better-documented.
Anyway, not sure if this helps you out 9 months after the fact, but thought I would share.
