Humour me and post your results from running this simplified version of your code with arg 4(assuming you have 4 cores?) & 50: #!/usr/bin/env perl
use strict;
use warnings;
use Math::BigInt;
use Parallel::ForkManager;
use Time::HiRes qw ( time );
use feature qw(say);
my $processes = shift;
my $pm = Parallel::ForkManager->new( $processes );
say qq(processes: $processes);
my $start=time;
for my $number ( 1 .. 50 ) {
$pm->start( $number ) and next;
my $factorial = Math::BigInt->bfac( 2000 ) for 1 .. 10;
$pm->finish( 0 );
}
$pm->wait_all_children;
say qq(fork: ), time - $start;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
