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?

The intent of this change is to increase iops on bluestore, it was implemented in 14.2.4 but it is a general bluestore issue not specific to Nautilus. /Maged
