Why? The kernel provides socket buffers for all protocols. Userland
can set them and the kernel does the appropriate
Hi tech@,
Per my understanding, the tcpbench.Sflag (Socket buffer size) should
only take effect when working in TCP mode. But according to my testing,
it also works when tcpbench client is in UDP mode:
(1) Set buffer size less than DEFAULT_UDP_PKT (1500 - 28):
# tcpbench -u -S 1471 127.0.0.1
