Someone recently posted on the x2go list that he had a problem with jerky videos playing remotely on Ubuntu, but solved it by installing a low latency kernel that was available as an alternative. 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 successfulat 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.)
