Hi ceph experts,
I deployed Nautilus (v14.2.4) and Luminous (v12.2.11) on the same hardware, and made a rough performance comparison. 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
