• 5cd2fe6d5   RDS/IW+IB: Set recv ring low water mark to 1/2 full. ... Browse Code »

  Currently the recv ring low water mark is 1/4 the depth. Performance
  measurements show that this limits iWARP throughput by flow controlling
  the rds-stress senders. Setting it to 1/2 seems to max the T3
  performance. I tried even higher levels but that didn't help and it
  started to increase the rds thread cpu utilization.
