Hi Josh, We are using firefly 0.80.9 and see both cinder create/delete numbers slow down compared 0.80.7. I don't see any specific tuning requirements and our cluster is run pretty much on default configuration. Do you recommend any tuning or can you please suggest some log signatures we need to be looking at?
