Here is the current results for 3.3.2 vs the mainline:
-O0 -O1 -O2 -O3
3.3.2 28.93 42.81 61.13 58.140
mainline 11.06 43.18 54.86 58.35
So we are faster at -O0 but slightly slower at optimization levels but if we trust the numbers for 3.0.4
compared to 3.3, we are still 30% slower than 3.0.4 except at -O0.
