I tried some of the specific RHEL suggested kernel tunables, and they don't work. For example, to use the "deadline" I/O elevator, you are supposed to be able to do this (assuming /dev/sda) # echo “deadline” > /sys/class/block/sda/queue/scheduler However, the kernel just reports: elevator: type “deadline” not found Is it possible the RHEL kernel is better optimized for server operations than the fedora kernel, which I would think is more geared towards a desktop? Perhaps there's a document that shows the features of the RHEL kernel specifically?
