I think I fixed this problem in 919e00b3e558 two days ago. Now it
seems to always use about 100% CPU and gets performance that is a bit
better than CPython, instead of spending all its time sleeping. Yay
:-)
I did some tests to measure how well PyPy and CPython perform when
running 2 or 3 threads in various microbenchmark-like situations
(running pure Python code; acquiring and releasing the same lock;
ping-pong between two threads; calling a fast or slow C function).
Now in all measured cases PyPy should perform not too badly. Actually
in most cases it was already better than CPython for fairness: for
example, when one thread runs pure Python code and the other thread
does many calls to a very fast C function, then CPython gives about
0.002% of the time(!) to the second thread and the rest to the first
one.
Thank you very much for taking care about this.
You rock. :)
