Ok to me. I'm getting some different results on LA664: 22031.284424 Compiler flags : -O2 -falign-labels=4 -falign-functions=8 -falign-loops=8 -falign-jumps=32 -DPERFORMANCE_RUN=1 -lrt vs the "best" one: 22075.055188 Compiler flags : -O2 -falign-labels=4 -falign-functions=32 -falign-loops=16 -falign-jumps=8 -DPERFORMANCE_RUN=1 -lrt maybe such a 0.1% difference is some random fluctuation, or hardware or kernel configuration difference anyway.
