Christoph's variable kernel page size support patch reminds me this 10 month old patch: http://marc.theaimsgroup.com/?l=linux-ia64&m=114074826111970&w=2 I strongly believe it is stable enough for 2.6.19. Reposted here for mainline consideration. ---- Patch set that remove pinned DTR per-cpu TLB requirement. 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 - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
