Hello cephers we have many (millions, small objects in our RadosGW system and are getting not very good write performance, 100-200 PUTs /sec.
I have read on the mailinglist that one possible tuning option would be to increase the max. number of files per directory on OSDs with eg. filestore merge threshold = 40 filestore split multiple = 8 Now my question is, do we need to rebuild the OSDs to make this effective? Or is it a runtime setting? I'm asking because when setting this with injectargs I get the message "unchangeable" back. Thanks for any insight.
