Hi all, > Speaking of which, what about some performance numbers?
OK, benchmarks done: http://ozlabs.org/~jk/projects/db/data/postgres.bcTruelen/ Summary: small increase in performance (~1-2% on my machine), at about 1.5 standard deviations from the mean. Profiles show a decent drop in hits within bcTruelen. However: Sysbench seems to be quite heavy with the fixed-width char types, so may end up calling bcTruelen more than most workloads. Would be nice to get some x86 numbers too, but I don't have a suitable machine here. So: The increase in performance is positive on this workload, albeit fairly minor. Downside is increased code complexity. Will re-send the patch once I work out how to get git to create a context diff...
