Compiling with -O0 is really quick, but the runtime is fairly slow. I haven't tried with -O1. -O2 takes a few seconds to compile, but that plus runtime is still faster than the pypy version with jit, but not by too much (I'm recalling the tests I did with the mandelbrot program specifically). I can get some actual numbers later today.

Sure I'll write up a post. This was a lot of fun, and I think it's a great way to teach people how pypy works.

what happens if you combine the BF to C with gcc -O0 or -O1?

Anyway, I think that if you feel like writing a post explaining your
experience with using pypy and its jit for writing an interpreter, we could
publish it on our blog.  I suppose it would be useful/interesting for other
people as well.

What do the others think?
