The conclusion is the thread count depends too much on what's being performed in the tasks.

2 threads can be enough for tasks taking full CPU time but, 10 000 threads can be a good count if there are a lot of task waiting for some answer (see http://www.bortzmeyer.org/combien-de-fils.html)

Thus the first best solution is to let the user set this thread count, according to his use.
Another option would be to continuously adapt this thread count according to the CPU usage.
