I am sorry for my delayed response.
I am sorry I was very ambiguous. In my experience,
I transfered a small data (1 M bytes) without losses.
And the results are:
1. from DragonFlyBSD to FreeBSD (HZ=1000): 1.2 Seconds
2. from FreeBSD to DragonFlyBSD (HZ=1000): 2.0 Seconds
3. from DragonFlyBSD to FreeBSD (HZ=10000): 1.1 Seconds
4. from FreeBSD to DragonFlyBSD (HZ=10000): 1.5 Seconds
(HZ represents the HZ value on the dummynet box on the path)
I made a web page of the result of my experiments at
This page also shows the graphs of the packet traces captured
