I used this parameters:
netperf -l 60 -H kano -t TCP_STREAM -i 10,2 -I 99,5 -- -m 128 -s 128K
-S 128K
so without nodelay.
With nodelay I've gotten:
batch-128: 128.91 mbit/sec
mainline-128: 140.57 mbit/sec
which is about 5 times less than withouth nodelay (~760 mbit/s)
Although nodelay results look more realistic.
