Just to conclude I did try the attached benchmark and I get the following on a x86_64 @ 2.40 GHz: 0: 61331143.40263957 allocations / second 1: 63644162.93924019 allocations / second 2: 177628727.5388474 allocations / second 3: 179850939.5413082 allocations / second 1 / 0: 103.7713621632905% boost 2 / 1: 101.2510431354494% boost So the fast_pool_allocator is already pretty fast and I can only get a 1% speed boost by allocating big memory blocks. So it doesn't look like there is any way to make the fast_pool_allocator any faster.
Correction: I get a 11% speed boost with the -O3 flag: 0: 60387275.67636769 allocations / second 1: 63133704.55951615 allocations / second 2: 169169529.8609596 allocations / second 3: 188535531.4062488 allocations / second 1 / 0: 104.5480258090584% boost 2 / 1: 111.447688931456% boost So I am not sure if this is worth the trouble. _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
