what are the Performance differences between User-space
threads and Kernel-supported threads.

Answer Posted / guest

In terms of context switch time, user-space threads are the
fastest, with two-level threads coming next (all other
things being equal). However, if you have a multiprocessor,
user-level threads can only be run on a single CPU, while
both two-level and pure kernel-supported threads can be run
on multiple CPUs simultaneously.
