Re: RBD performance - tuning hints / major slowdown effect(s)

Sorry Dieter,

Not trying to say "you are wrong" or anything like that - just trying to add to the problem solving body of knowledge that from what *I* have tried out the 'sync' issue does not look to be the bad guy here - altho more analysis is always welcome (usual story - my findings should be confirm-able by others doing similar tests)!

regards

Mark

Mark, Inktank,

OK, it is very likely that 'sync_file_range' is not the major slowdown 'culprit'.

But, which areas (design, current implementation, protocol, interconnect, tuning parameter, ...)
would you rate as 'major slowdown effect(s)' ?
