I'm sorry for the confusion there. What I meant is that I compiled 2.7.12 on 14.04 and found that it had the same performance as 2.7.6 (from the default Ubuntu python package) on 14.04. I also loaded Xenial's kernel on the 14.04 installation and found no performance difference either.
The problem seems to be unique to 2.7.12 on 16.04.
