  "message": "RDS/IW+IB: Set recv ring low water mark to 1/2 full.\n\nCurrently the recv ring low water mark is 1/4 the depth.  Performance\nmeasurements show that this limits iWARP throughput by flow controlling\nthe rds-stress senders.  Setting it to 1/2 seems to max the T3\nperformance.  I tried even higher levels but that didn\u0027t help and it\nstarted to increase the rds thread cpu utilization.\n\nSigned-off-by: Steve Wise \u003cswise@opengridcomputing.com\u003e\nSigned-off-by: Andy Grover \u003candy.grover@oracle.com\u003e\nSigned-off-by: David S.
