Apart from what's already been mentioned about checking your configuration, keep in mind the osd bench is entirely a local test — if it says 100MB/s, that means your OSD disk can do 100MB/s, and increasing the network connectivity isn't going to change that. :) -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
