I selected a few of the supported benchmarks by MMTests in order to keep to a reasonable time frame. The aim was to see the impact of normal (no RT) workloads with different preempt configurations on mainline and RT patched kernel. I tried to not to change other configuration flags except the preempt one. There are some small difference due to dependencies but the rest looks ok to me. http://www.monom.org/rt/mmtests/ Suggestion, improvements, comments? cheers, daniel
