And I was just about to upgrade. :) How is this even possible with this change[0] where 50-100% iops lost?

The result seems Luminous is much better, which is unexpected. My setup: 3 servers, each has 3 HDD OSDs, 1 SSD as DB, two separated 1G network for cluster and public. Pool test has 32 pg and pop numbers, replicated size is 3. Using "rados -p bench 80 write” to measure write performance. The result: Luminous: Average IOPS 36 Nautilus: Average IOPS 28 Is the difference considered valid for Nautilus?
