Iperf gives about 7Gb/s between a radosgw host and one of my OSD hosts (8
disks, 8 OSD daemons, one of 3 OSD hosts).  When I benchmark radosgw with
cosbench I see high TCP retransmission rates (from sar -n ETCP 1).  I don't
see this with iperf.  Why would Ceph, but not iperf, cause high TCP
retransmission rates?

 Thank you
