Random_Walk has asked for the wisdom of the Perl Monks concerning the following question:

I am using threads and I want the main thread to give some time to its workers. The main thread enqueues work for them and I don't want the queue to get too big. The docco says: You may do use threads qw(yield), and then just use yield() in your code. I am using it in the main thread with no errors but I am not sure it is doing anything.

At this point I am early in development and there is not much load on my system. If yield is not working in the main thread would doing a uSleep have a similar effect? Any other suggestions on an efficient way to keep the queue full but not too full?

Cheers,
R.

    Try my self-limiting queue implementation from the spoiler in Re^4: dynamic number of threads based on CPU utilization.

    Set the size to at least 4 times the number of elements as you have consumer threads and then adjust up and down until you hit the sweet spot for your application.

      Thank you. I will be using that, a much more elegant solution
