      IO_uring seem te be quite promising with ceph

      This implements low-level IO engine, which utilizes brand-new io_uring IO interface: https://lwn.net/Articles/776428/ The following basic config was used for fio_ceph_objectstore: rw=randwrite ...

      Code:
       bluestore_iouring=false
      
         4k  IOPS=25.5k, BW=99.8MiB/s, Lat=0.374ms
         8k  IOPS=21.5k, BW=168MiB/s,  Lat=0.441ms
        16k  IOPS=17.2k, BW=268MiB/s,  Lat=0.544ms
        32k  IOPS=12.3k, BW=383MiB/s,  Lat=0.753ms
        64k  IOPS=8358,  BW=522MiB/s,  Lat=1.083ms
       128k  IOPS=4724,  BW=591MiB/s,  Lat=1.906ms
      
      bluestore_iouring=true
      
         4k  IOPS=29.2k, BW=114MiB/s,  Lat=0.331ms
         8k  IOPS=30.7k, BW=240MiB/s,  Lat=0.319ms
        16k  IOPS=27.4k, BW=428MiB/s,  Lat=0.368ms
        32k  IOPS=22.7k, BW=709MiB/s,  Lat=0.475ms
        64k  IOPS=15.6k, BW=978MiB/s,  Lat=0.754ms
       128k  IOPS=9572,  BW=1197MiB/s, Lat=1.223ms
      
      Overall IOPS increase is the following:
      
         4k  +14%
         8k  +42%
        16k  +59%
        32k  +89%
        64k  +85%
       128k  +102%

          I'll wait for at least 5.1.4 before upgrading to it. I've been burnt enough in the past to run new "stable" releases.

            yeah, I also wait for the first .1 security and bug-fix release before I even do the #t2sde package, ... https://t2sde.org/packages/linux

                  Maybe it's 4:20 all day long for Linus since that occasion.
