The .= operator is one of Perl's slowest. It generally has to allocate a
completely new SV (internal data structure for scalars), copy over the original
string, then append the new content. And you're appending *twice*, for each
iteration. At least express <<"#" . $anewvalue>> as "#$anewvalue".
If memory is not an issue, the following would be significantly faster:
my $count = 0;
@pmem::arr = ();
for(0..1125000)
{
push(@pmem::arr, "#$anewvalue"); #$anewvalue is random;
$count++;
print $count,"\n";
}
$pmem::arr = join('', @pmem::arr);
I have no idea what would be causing the "stuttering", however.
