Rather than having different builds of the kernel, RHEL has low
latency performance tuning guides. These presumably apply to CentOS
also:

Low Latency Performance Tuning Guide for Red Hat Enterprise Linux 6
https://access.redhat.com/articles/221153

Low Latency Performance Tuning for Red Hat Enterprise Linux 7
https://access.redhat.com/articles/1323793
(This one requires a RHEL subscription to access. It's a PDF like the
RHEL6 guide.)
