In the past thread termination (in SeeFusion) seems to take about 5 minutes to recover from.   I guess I could do a stack trace if someone told me what and how to do it.   Robert P.

What was more important?????????   4 hours between 1-2 minute lock ups, or 2 hours between 40 minute lock ups?   I think I did the only logical thing I could do considering my pathetic lack of knowledge. I am sure that one day I will comment to myself how IGNORANT I was at this time.   Robert P.

Threads are like available channels that can execute code in tandom.  You have a queue of requests and the threads are the ones that handle all of the requests.   If you have 100 requests and 10 threads handle them, that is faster than 100 requests and 2 threads handling them.  The only thing that has to observed is how much memory is best suited for the threads.  Each threads takes up resources as individual and asynchronous processes.   I typically increase my threads over time and watch the performance of a box.  I try to keep the CPU to around 30% if possible.  60-70% works just fine if you have over 1000 queues per minute.
