@Maciej: it doesn't make a lot of sense. Looking at this graph: http://speed.pypy.org/comparison/?exe=2%2B35,4%2B35,1%2B172,3%2B172&ben=11,14,15&env=1&hor=false&bas=none&chart=normal+bars
slowspitfire is much faster than the other two. Is that because it performs more iterations? Also, how come pypy-c-jit is faster than cpython or psyco precisely in cstringio, where performance should be dependent on cstringIO and thus be more similar across interpreters? 2010/12/13 Leonardo Santagada <[email protected]>: > why not have only 2 versions, both with the same size table and name > one spitfire_cstringio and the other spitfire_strjoin?
