Aleksey Shipilev commented on HARMONY-5703:
-------------------------------------------
Baseline measurements on 8-core Clovertown:
S = Sun 1.6.0_05
H = Harmony r643000
R = H / S
threads=1 H=5144 S=243778 R=47.4
threads=4 H=19850 S=992522 R=50.0
threads=8 H=39899 S=2082282 R=52.2
threads=12 H=47800 S=2400955 R=50.2
threads=16 H=55802 S=2967455 R=53.2
Good scalability in both cases, but RI is 50x faster.
