PyPy 1.8 - business as usual
PyPy to me looks like a great effort and a technological tour de force. But I wish they would talk _more_ about why and when PyPy will be _slower_ than CPython on their site . Here is why.<p>I tried to run some of my scripts on PyPy and performance was invariably worse (about 50% worse). And my first reaction was: PyPy is not delivering on its promises. Only later, on some forum I read that PyPy does not perform well on large dictionaries (and this is essentially what I do in my scripts). Have I known it in advance, my first impression of PyPy would be much better.
