MapTask$MapOutputBuffer.compare( ) method

With JVM inlining enabled, profiles of Terasort run show more than 3% time spent in MapTask$MapOutputBuffer.compare( ) method in each of the Map JVMs. In this particular configuration there are 8 Map JVMs. So a big chunk of time is spent in this particular method. With JVM inlining disabled
