I am trying to tune the RHEL6.4 Kernel to handle server style load for of my application. With RHEL 6 scheduler has been changed to CFS and with RHEL 5 my application works fine. I would like change the preemptive option of the kernel to none. I don't know if changing this value in /boot/config-2.6.32-358.el6.x86_64 will work or not.In addition I want to set the value to set in the kernel.sched_features for disabling preempt using the sysctl command.
How to set CONFIG_PREEMPT_NONE in RHEL 6.4 (linux)
