The above performance data is on Piketon. I test on Calpella(mobile), the
degradation is about ~16%.
I retest the 7b1a5024df96070b and make a summary:
Piketon Calpella
git-9eabe28: 15500000 7760000
git-16fb786: 9650000(37%↓) 6470000(16.6%↓)
git-7b1a502: 13700000(11.6%↓) 6820000(12%↓)
Calpella: Core(TM) i5 CPU M 520 @ 2.40GHz
Piketon : Core(TM) i5 CPU 650 @ 3.20GHz
