Tried again, this time getting some stats with MCACHE_STATS 1, to check if my patch is defeating the cache: Without my patch: $ time ./python performance/benchmarks/bm_chaos.py --worker -l1 -w0 -n1 --filename chaos.ppm --width=512 --height=512 --iterations 50000 chaos: Median: 2.51 sec -- Method cache hits = 16581735 (99%) -- Method cache true misses = 4092 (0%) -- Method cache collisions = 28542 (0%) -- Method cache size = 96 KB With my patch: $ time ./python performance/benchmarks/bm_chaos.py --worker -l1 -w0 -n1 --filename chaos.ppm --width=512 --height=512 --iterations 50000 chaos: Median: 2.53 sec -- Method cache hits = 16582260 (99%) -- Method cache true misses = 4096 (0%) -- Method cache collisions = 28012 (0%) -- Method cache size = 96 KB ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28866> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
