What happens if you run three threads on CPU-intensive tasks that are
only CPU-intensive: that is, take some function which does nothing but
arithmetic on local data, say, and run it in multiple threads?

(Without any more information on what you are actually doing, it is
difficult to guess what might be going wrong; without access to your
system and your code, it's difficult for any member of this list to
diagnose the problem.  The above suggestion is the first thing I would
suggest you try, but it might lead you to try other things to
determine the bounds of the problem.)

Cheers,
