--- Comment #5 from likan_999.student at sina dot com 2012-07-24 00:17:10 UTC --- @Paolo Carlini: can you talk more about how to experiment with max_load_factor? As long as I use the same max_load_factor for 4.6 and 4.7, I can still see the performance difference (3x slower is the best result): max_load_factor gcc-4.6.2 gcc-4.7.1 0.2 1.600s 7.650s 0.5 1.125s 4.251s 1.0 1.004s 3.378s 2.0 0.914s 20.471s 5.0 0.917s 29.132s
