What is the effect on packet-per-second performance?  (eg aggregate,
burst-mode netperf TCP_RR with TCP_NODELAY set or perhaps UDP_RR)

I used uperf with TCP_NODELAY and 16 threads sending from another
machine 64000-sized writes for 60 seconds.

I get 5898op/s (3.02Gb/s) without the patch against 18022ops/s
(9.23Gb/s) with the patch.

I was thinking more along the lines of an additional comparison, 
explicitly using netperf TCP_RR or something like it, not just the 
packets per second from a bulk transfer test.
