[ceph-users] Performance, and how much wiggle room there is with tunables

 In my cluster, rados bench shows about 1GB/s bandwidth.  I've done some
tuning:

[osd]
osd op threads = 8
osd disk threads = 4
osd recovery max active = 7


I was hoping to get much better bandwidth.  My network can handle it, and
my disks are pretty fast as well.  Are there any major tunables I can play
with to increase what will be reported by "rados bench"?  Am I pretty much
stuck around the bandwidth it reported?

 Thank you
