We have a number of delays when we switch to new layouts that were added to make the tests visually easier to follow, together with blinking status bars. Shorten the delays and avoid blinking the status bar if $FAST is set to 1 (no demo mode). Shorten delays in busy loops to 10ms, instead of 100ms, and skip the one-second fixed delay when we wait for the status of a command. Cut the duration of throughput and latency tests to one second, down from ten. Somewhat surprisingly, the results we get are rather consistent, and not significantly different from what we'd get with 10 seconds. This, together with Podman's commit 20f3e8909e3a ("test/system: pasta_test_do add explicit port check"), cuts the time needed on my setup for full test run from approximately 37 minutes to...: $ time ./run [exited] PASS: 165, FAIL: 0 Log at /home/sbrivio/passt/test/test_logs/test.log real 15m34.253s user 0m0.011s sys 0m0.011s Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Tested-by: David Gibson <david@gibson.dropbear.id.au>
