Thread Load Balancing

Can anyone here give me tips on how to make threads more efficient and how to balance the load of multiple threads?

Thanks.

Also bear in mind the O/S as:

The DCE pthreads package (also known as CMA threads, or user-space threads;
or DCE pthreads) is a purely user-level threads package; there is no kernel
support in HP-UX CMA threads.

HP-UX 11.0 provides kernel support with POSIX threads and hence,
the POSIX threads are supported over these kernel threads.
HP-UX 11.0 POSIX threads provides a 1:1 mapping of user-level threads
to kernel threads. This means that for every user-level thread, there is
a corresponding kernel thread. At this time, HP-UX allows a default of
64 simultaneous threads in a user process. This limit is configurable.
