Did you use some additional patches in your Jewel build? In my own testing I'm seeing only marginal improvements in plain Jewel vs. Hammer. To have a fair comparison, you should also use the same QD for both Hammer and Jewel. Finally, the avg latency for 4k ops isn't that significant, could you also add numbers for max latency or 99.xx percentile? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
