Yes. I agree. I think we should also consider the total time consuming of t= he test. As more cores are involved in the lock contention, more time is re= quired to complete the test.=20 > > In fact with this one we'll have 3 lock methods, I think it makes > > sense to have one united UT framework for them, so only actual > > lock/unlock would be different. +1. =20 Since the APIs of MCS lock is different with spinlock and ticket lock, so I= am wondering that what will this united UT framework look like? Will it be the same test case that integrates 3 sets of lock tests running = with different cmd line? > +1 >=20 > > Konstantin > > > > > >=20 > <snip> Thanks, Phil Yang
