Message288072
Hi,
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 |
