There is no magic option to make device snappier, other than fast lane. You can choose the performance governor for both CPU and gpu, which will run all cores at max freq always, but you won't see much of a difference in speed, but will lose power. Not worth it. Go for default with fast lane
The performance governor is one of the worst. Having the phone run at max speed doesn't equal max performance. So from what I read here, I cannot do anything else. I could play with the values of the blu_spark governor but that's a pain in the behind.
Thanks a lot everyone for your replies.
