Jeffrey Yasskin <jyass...@gmail.com> added the comment: Here's a port of threadedceval5.patch to trunk. It passes the tests. I haven't benchmarked this exact patch, but on one Intel Core2, a similar patch got an 11%-14% speedup (on 2to3 and pybench).
I've also cleaned up Jakob Sievers' vmgen patch (representing forth-style dispatch) a bit so that it passes all the tests, and on the same machine it got a 13%-17% speedup. The vmgen patch is not quite at feature parity (it throws out support for LLTRACE and a couple other #defines), and there are fairly good arguments against committing it to python at all (it requires installing and modifying vmgen to build), but I'll post it after I've ported it to trunk. Re skip and paolo: JITting and machine-specific assembly will probably be important to speeding up Python in the long run, but they'll also take a long while to get right, so we shouldn't let them distract us from committing the dispatch optimization.
