I have FileVault enabled on all my Macs. Not done any back to back but find situation perfectly acceptable.

My understanding is that the main effect is a small penalty during boot up while the drive is unlocked.

Don't really notice it much other than during boot. 2016 rMB is suppose to be much better than 2015 per Ars review.
