The ROM is GOOD but not BEST or better than Iced Bean 3.0 but really not bad its only first your experiance))) Good starting!
BTW Antutu shows in airplane mode 4250 and later 4190 then 4222 POOR ! Iced Bean 3.0 is 5464 the best score for RAY !
Good Luck in development !
Did you OC before test?
Because this rom don't have no frills, and default clock is 806.
Here is my result without sd card test because my sd card is sh.it
And I think this is one of the best ICS rom I ever tested:good:
