Hello monks

I've got a foreach loop like this:

OUTER: foreach my $line (<GZIP>) {

                                INNER: for ( my $i = 0; $i < scalar @{
+$categories{$k}->{traces}}; $i++ ) {

                                        if ( $line =~ /^($categories{$
+k}->{traces}[$i]->{regex})/ ) {

                                                my @lista = split /;/,
+ $line;
                                                $A += $lista[${$catego
+ries{$k}->{traces}[$i]->{calc}}[0]];
                                                $B += $lista[${$catego
+ries{$k}->{traces}[$i]->{calc}}[1]];
                                                $C += $lista[${$catego
+ries{$k}->{traces}[$i]->{calc}}[2]];
                                                next OUTER;

                                        }

                                }

                        }

                        close(GZIP);

Since the GZIP filehandle has millions of lines, I'm trying to understand if I can find an efficient way to parallelize the foreach loop, so that I can have, say, 5 $line processed together.

I haven't found a solution through the internet or docs, but probably it was me not searching for the correct thing.

Any suggestion will be appreciated. Thanks!
