Hello Monks

I came across the MCE::Map utility and wanted to try out.

Here's what I see...

testuser@linux-mint:~$ cat just_map.pl 
use strict;
use warnings;

my @biglist = (1..10000000);
my @squared_big_list = map { $_ * $_ } @biglist;

testuser@linux-mint:~$ time perl just_map.pl 

real    0m1.743s
user    0m1.496s
sys    0m0.248s



testuser@linux-mint:~$ cat mce_map.pl 
use strict;
use warnings;
use MCE::Map;

my @biglist = (1..10000000);
my @squared_big_list = mce_map { $_ * $_ } @biglist;

testuser@linux-mint:~$ time perl mce_map.pl 

real    0m5.401s
user    0m16.008s
sys    0m4.658s
testuser@linux-mint:~$

Why is the time more with MCE::Map? I tried it with various versions of perl (5.16, 5.24, 5.32 and 5.34) and I get similar results....Either I'm reading something wrong or my understanding is messed up.

In reply to I thought MCE::Map is faster than usual map. What am I missing? by Anonymous Monk
