Hi guys, I unfortunately missed this. Yes, the fifo size provided is the number of kB and yes you should be able to do 4MB (fifo-size 4096) or even higher.
The “stuck clients” warning is just a notification, the test can still finish. To make sure you give the test enough time, add “test-timeout <timeout-in-seconds>” to the list of parameters.
