Instead we use DTC to map that translation. With these two patches, we measured substantial performance gain on a database benchmark, in the vicinity of 1.6%. I've also done extensive performance measurement on two other industry standard benchmarks (cpu, java), and have found to have small gain on those workloads. Detail description in the follow on patches. - Ken
