Maybe a bit of topic, just curious what speeds did you get previously?
Depending on how you test your native drive of 5400rpm, the performance
could be similar. 4k random read of my 7200rpm/5400 rpm results in
~60iops at 260kB/s.
I also wonder why filestore could be that much faster, is this not
something else? Maybe some dangerous caching method was on?
Then again, filestore will use the OS fs caches normally, which bluestore will not, so unless you tune
your bluestores carefully, it will be far easier to get at least read caches to work in your favor with
filestore if you have RAM to spare on your OSD hosts.
May the most significant bit of your life be positive.
