I installed the rom a few days ago and the whole reason I finally installed this rom is because stock rom got so laggy after I'd used it for a week.
So far this rom seems ot have better performance.
When I first installed the rom Play store wouldn't launch after my first reboot. So I installed playstore from
HERE and it didn't fix it but when I went to settings>Apps and disabled playstore it asked to uninstall playstore and restore the default so I did that and then re-enabled playstore and everything has been fine since then.
So far the phone hasn't been lagging like stock was but I think I might need to give it a few more days because stock was fine at first too but then was always eating ram.
