I often experience high CPU load on Xorg process. Most of the time the behavior cannot be reproduced. However, with RHEL 6.5, I have noticed quite often the Firefox with various splash displays trigger heavy CPU load. Once the FF tab is closed or the FF is closed then the Xorg settles to normal cpu utilization. Lately I have been experiencing heavy CPU loads with RHEL 6.7 kernel. Sometimes Xorg high CPU load is experienced with some home grown applications. I am using nVidia driver, which was provided by nVidia. In my environment using Vesa driver doesn't produce the desired rendering. Further since I have multi-displays, using generic nouveau driver is not an option. Any resolution or a workaround is appreciated.
