What is most CPU efficient method to make the worker threads wait for tasks?

Check out this implementation of a BlockingQueue . If the queue is empty, it uses Monitor.Wait() to put the thread to sleep. When an item is added, it uses Monitor.Pulse() to wake up a thread that is sleeping on the empty queue.

You currently have Thread. Sleep(0) in your Work method for where there are no queue items. Change it to anything greater than 0 and your CPU use will go down.
