I've tested it on FC3, its great!
They are now in the process of getting rid of "Big Kernel Lock". BKL freezes the kernel to prevent critical data from being accessed at the same time as well as code that needs to be executed without interruption. BKL happens hundreds of times a second and with smarter code BKL can be prevented. With CONFIG_PREEMPT_BKL it will simply lower latency by reducing and preempting these BKL's. It will definitely help on the server and desktop side. |
