[pypy-dev] (unexpectedly) bad performance of stackless and greenlet on PyPy

[Denis Bilenko]

Hi!

I've micro-benchmarked stackless and greenlet module in PyPy and was
quite surprised with the results. According to this benchmark
stackless.channel is 100x times slower on PyPy (vs Stackless) and
greenlet is 20x times slower on PyPy (vs CPython).

Is this a bug in benchmark (or PyPy) or is it the expected current
state of stackless features on PyPy?

Cheers,
Denis.
