Set response size of TCP_RR test in netperf to 0 bytes

I'm trying to figure out how to set response size of TCP_RR test in netperf to 0 bytes.



I am using the following command



netperf -t tcp_rr  -- -r 5,0


and I am inspecting packets in Wireshark, and what I see is that even though the request is 5 bytes, as specified by me, sometimes the length of the response packet by netserver is ~16K bytes. If I change it to 



netperf -t tcp_rr  -- -r 5,1


the length of the response packet is 1 byte. Is it not possible to set the response size to 0 bytes?



What I want is for server to never send me any packets with data in them. The reason for this is because I have a network setup where host 1 sends data to host 2 and I'm trying to measure how fast host 2 is ACKing the data, because host 2 is using a TCP stack I manually wrote as an exercise. I thought TCP_RR test would be best for this test scenario, but if there is a better test, I would rather use that instead of TCP_RR.



Thanks

Question : What is the origin of the phrase "under your belt"? A google search revealed some webpages (e.g. [1]) that assert its origin is related to consumption of food -- once a meal has been eaten, it's under your belt (which is a relief). However, with such websites, I have no way to determine fact from "random guy on the internet making stuff up". etymology idioms ...
