dotnet thread pool, tips from Pravin

http://www.howdoicode.net/2013/04/net-thread-pool.html has some good tips

Pool threads are always background. Un-Configurable.

Consider creating your own thread if Synchronization needed — If we rely on synchronization to start, wait and stop the work done by the thread, then it is very likely that the task duration will increase and could lead to starvation very soon. If we have to use WaitHandles, locks or other synchronization techniques – then creating our own threads would be a better option.

Consider creating your own thread if Longer duration of work — Thread pool is to be used only when the work is of short duration. The faster the thread completes its work and goes back to the pool, the better performance. If threads are assigned to work for something very long, after some time starvation could occur. New threads are not created in the pool after a limit is reached, and if all threads are busy – the work may not be performed at all.
