I mean numa/core was 97% faster. That transforms into 
balancenuma-v4 being 50.5% slower.

Your numbers from yesterday showed an even bigger proportion:

AUTONUMA BENCH
                                          3.7.0                 3.7.0                 3.7.0                 3.7.0                 
3.7.0                 3.7.0
                                rc6-stats-v4r12   rc6-schednuma-v16r2 rc6-autonuma-v28fastr3	  rc6-moron-v4r38    rc6-twostage-v4r38  rc6-thpmigrate-v4r38
Elapsed NUMA01                1668.03 (  0.00%)      486.04 ( 70.86%) 	   794.10 ( 52.39%)	 601.19 ( 63.96%)     1575.52 (  5.55%)     1066.67 ( 36.05%)

In your test numa/core was 240% times faster than mainline, 63% 
faster than autonuma and 119% faster than 
balancenuma-"rc6-thpmigrate-v4r38".

Thanks,

	Ingo
