It's frustrating to me that even experts here don't measure latency as a
first priority. The tooling has been available for years to do this. And
it's only getting better and more feature rich, e.g. bounce-back.
--bounceback[=n]
run a TCP bounceback or rps test with optional number writes in a burst
per value of n. The default is ten writes every period and the default
period is one second (Note: set size with --bounceback-request). See
NOTES on clock unsynchronized detections.
--bounceback-hold n
request the server to insert a delay of n milliseconds between its read
and write (default is no delay)
--bounceback-no-quickack
request the server not set the TCP_QUICKACK socket option (disabling TCP
ACK delays) during a bounceback test (see NOTES)
--bounceback-period[=n]
request the client schedule its send(s) every n seconds (default is one
second, use zero value for immediate or continuous back to back)
--bounceback-request n
set the bounceback request size in units bytes. Default value is 100
bytes.
--bounceback-reply n
set the bounceback reply size in units bytes. This supports asymmetric
message sizes between the request and the reply. Default value is zero,
which uses the value of --bounceback-request.
--bounceback-txdelay n
request the client to delay n seconds between the start of the working
load and the bounceback traffic (default is no delay)
