And also the time it took from one block of 50 to other block of 50 and it was the same time as the longer one. Of course. How could it be otherwise? If you draw 10 parallel lines of different lengths: `--------------- ------ ---------------- ---- - ----------- -------- ------ -------------- -----` [download] Is there any way to make the overall width less than the longest line? Same thing. As an aside, but entirely relevant; running 50 tasks concurrently on 4 cpus will take longer than running those same 50 tasks; but only 4 at any given time.

Sorry, I'm new to this. I don't understand why 50 tasks concurrently will take longer than running packs of 4.	[reply]

Change your code to: `my $pm = Parallel::ForkManager->new(4); my $i = 0; while(i<50){ $pm->start and next; processStream($stream); $i++; $pm->finish; # do the exit in the child process } $pm->wait_all_children();` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

No packs. Just run 4 tasks, if one ends, start another one. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply]
