Thread vs ThreadPool

Question

What is the difference between using a new thread and using a thread from the thread pool? What performance benefits are there and why should I consider using a thread from

Answer 1

Using a pool is a good idea, if you don't know or can't control how many thread will be created.

Just have an issue with a form using thread to update some field from a database on a positionchanged event of a list control(avoid freez). It took 5 minutes for my user to have an error from the database (too many connexion with Access) because he was changing the list position too fast...

I know there is other way to resolve the base problem (including not using access) but pooling is a good start.
