Subject: [Rpm] iperf 2 bounceback - independent request/reply sizes
Date: Fri, 12 May 2023 08:46:19 -0700 [thread overview]
Message-ID: <e8c0c53be670bd3e27dac6bab9dbdb55@rjmcmahon.com> (raw)

Hi All,
I received a recent diff for iperf 2 to support independent request and
reply sizes for the bounceback test. It's nice to get diffs that can be
patched in!
[root@ctrl1fc35 ~]# iperf -c 192.168.1.231 --bounceback
--bounceback-reply 512K
------------------------------------------------------------
Client connecting to 192.168.1.231, TCP port 5001 with pid 305401 (1
flows)
Bounceback test (req/reply size = 100 Byte/ 512 KByte) (server hold
req=0 usecs & tcp_quickack)
Bursting request 10 times every 1.00 second(s)
TCP congestion control using reno
TOS set to 0x0 and nodelay (Nagle off)
TCP window size: 85.0 KByte (default)
