The bandwidth of the network is much higher than that. The bandwidth I mentioned came from "rados bench" output, under the "Bandwidth (MB/sec)" row. I see from comparing mine to others online that mine is pretty good (relatively). But I'd like to get much more than that.
Does "rados bench" show a near maximum of what a cluster can do? Or is it possible that I can tune it to get more bandwidth?
