You should.

Performance is literally 2X to 5X different between kernels.
Josh, there seems to be an inconsistency in your blog. You say 3.10.X is safe, but the graph you show with the poor performance seems to be from 3.13.X which as I understand it is a later kernel. Can you clarify which 3.X kernels are good to use and which are not?
