[Python-Dev] Python 3 optimizations, continued, continued again... (original) (raw)

Hello,

Could you try benchmarking with the "standard" benchmarks: http://hg.python.org/benchmarks/ and see what sort of performance gains you get? Yeah, of course. I already did. Refere to the page listed below for details. I did not look into the results yet, though.

How portable is the threaded interpreter? Well, you can implement threaded code on any machine that support indirect branch instructions. Fortunately, GCC supports the "label-as-values" feature, which makes it available on any machine that supports GCC. My optimizations themselves are portable, and I tested them on a PowerPC for my thesis, too. (AFAIR, llvm supports this feature, too.)

Do you have a public repository for the code, so we can take a look? I have created a patch (as Benjamin wanted) and put all of the resources (i.e., benchmark results and the patch itself) on my home page: http://www.ics.uci.edu/~sbruntha/pydev.html

Regards, --stefan
