This is interesting: https://lwn.net/Articles/713963/

So, if you rely on 3.18.y, you should upgrade. But really, go use 4.4.y or 4.9.y, those are both much better, and far more secure.

14.04 is using 3.13 as default (Ubuntu provides extended support for it by backporting patches and so) but it worth considering moving to Linux kernel 4.4 which is officially supported by Ubuntu and is apt-get install away.

The Vagrant development box and the ServerCentral servers are on Ubuntu 14.04 and kernel 3.13 (the default).

4.4-family has quite a lot of improvements including a major patches about the NUMA scheduling which seems to affect the current preview of Round 14.

The idea is mentioned here about Vagrant image: 2496.

There is a ongoing migration to newer Ubuntu. So this becomes irrelevant.
