in reply to Use Coro for reading EventLog on many pc's?

Coro offers a cooperative multitasking solution, and your calls to process_pc aren't cooperating (so to speak). Get rid of the call to cede (which would be useless in a functioning Coro version anyway) and switch use Coro; to use threads;.

Note that both Coro's and threads's async functions return an object (not some id).

    Thank you much. That helped speed things up.

    Now to re-read the docs for threads to figure out how to limit the number of threads I have so I don't saturate my network connection. I initially was looking at Thread:Queue but I wasn't understanding it properly. Maybe with this bit of helpful knowledge I can grok the docs.


      Thread::Queue is indeed the way to go.

      my $q = Thread::Queue->new(); my @threads; for (1..MAX_WORKERS) { push @threads, async { while (my $job = $q->dequeue()) { do_job($job); } }; } # Give work to the workers. for my $job (...) { $q->enqueue($job); } # Signal the workers to exit. $q->enqueue(undef) for 1..MAX_WORKERS; # Wait for the workers to finish. $_->join() for @threads;
