They do not have the kernel built preemptively, this you can check by
looking at the config file they ship, I was not able to get rid of the stutter
in the video without enabling this on my other boxes and building a kernel.-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

That made me curious as to whether CentOS has an equivalent - or a way to build something similar. Les, I can help you with CentOS 6 kernels but I haven't been successful at installing a custom kernel on CentOS 7, for some reason after I update grub2 then try to boot, I get a pointer alignment error and can't even get the grub boot screen up. But I have been successful with CentOS 6 and can provide assistance if needed.[...] 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.) -Mike#2
