While I'm looking into the possibilities provided by the
other posters, these tips don't require more advanced
knowledge than I have ;-).
Thank you for warning me about the anonymous array overhead.
Will change that immediately.
Furthermore, I'm on little endian, so the string comparison
should work just fine. However, I don't want to sort on
the remainder of the string as it is now. Will run a test
first, and post the results here.
Thanks a lot,

Update: Must have made some difference in memory
usage, but it's still way too much. Made a rough calculation
of the memory usage with system monitor (gnome) and this
my $f = 2;
print "Increasing memory print each step by a factor $f\n\n";
print "\tCreating array of $size items...Press enter to continue....
my $b = <STDIN>;
print "...done. Press enter to continue.";
$b = <STDIN>;
$b=~ /[qxQX]/ and exit;
$size *= $f;
It's about 44 megabytes for every million items in an array.
No way my 12 M records are going to fit in physical memory. I'm back
to Radixsort and alike.
