I don't have detail perf number for sync io latency now.
But a few days ago I did single OSD single io depth benchmark. In
short, Firefly Dumpling Hammer per op latency.
It's great to see Mark's benchmark result! As for pcie ssd, I think
ceph can't make full use of it currently for one OSD. We

Hi Alex,
Thanks! I didn't tweak the sharding settings at all, so they are just
at the default values:
OPTION(osd_op_num_threads_per_shard, OPT_INT, 2)
OPTION(osd_op_num_shards, OPT_INT, 5)
I don't have really good insight yet

Hi Stephen,
It's a benchmark automation tool we wrote that builds a ceph cluster and
then runs benchmarks against it. It's still pretty rough (no real error
checking, no documentation, etc). We have some partners that are
interested in using it too and I'd like to make it useful for the
Awesome! Thanks Much!
