Hi Travis,
In my experience, after converting OSDs from hdd FileStore with ssd journals to hdd BlueStore with RocksDB and it's WAL on ssd, FileStore is significantly faster.

Pure ssd OSDs would however be much faster using BlueStore...

Since bluestore was declared stable in Luminous, is there any remaining
scenario to use filestore in new deployments? Or is it safe to assume that
bluestore is always better to use in Luminous? All documentation I can
find points to bluestore being superior in all cases.
Thanks,
Travis
