* test/perf: Always use /sbin/sysctl in tcp testStefano Brivio2022-09-221-3/+3

* test/perf: Check for /sbin/sysctl with which(1), not simply sysctlStefano Brivio2022-09-221-1/+1
| | | | | | | | | | Otherwise, we're depending on having /sbin in $PATH. For some reason I didn't completely grasp, with the new command dispatch mechanism that's not the case anymore, even if I have /sbin in $PATH in the parent shell.

* test: Rewrite test_iperf3David Gibson2022-09-071-1/+1
| | | | | | | | | | | | | | | test_iperf3() is a pretty inscrutable mess of nested background processes. It has a number of ugly sleeps needed to wait for things to complete. Rewrite it to be cleaner: * Use the construct (a & b & wait) to run 'a' and 'b' in parallel, but then wait for them both to complete before continuing * This allows us to wait for both the server and client to finish, rather than sleeping * Use jq to do all the math we need to get the final result, rather than jq followed by some complicated 'bc' mangling Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Parameterize run time for throughput performance testsDavid Gibson2022-09-071-20/+22
| | | | | | | | | | | | Currently all the throughput tests are run for 30s. This is reflected in both the actual parameters given to the iperf commands, but also in the matching sleeps in test_iperf3. Allow this to be adjusted more easily with a new parameter to test_iperf3.

* test: Combine iperf3c and iperf3s into a single DSL commandDavid Gibson2022-09-071-34/+17
| | | | | | | | | | | | | | | | | These two commands in the DSL to run an iperf client and server are always used together, and some of the parameters must match between them. The iperf3s must also be run more or less immediately after iperf3c, since iperf3c will run a client in the background after a sleep and requires a server to be running before it will work. A bunch of things can be made cleaner if we make a single DSL command that runs both sides of the test. For now make the combined command work exactly like the two commands together did, warts and all. This does lose the ability for the DSL scripts to give additional options to the iperf3 server, but we weren't using that anyway. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Explicitly list test files in test/run, remove "onlyfor" supportDavid Gibson2022-07-141-1/+0
| | | | | | | | | | | | | | | | | Currently test/run uses wildcards to run all of the tests in a directory. However, that wildcard list is filtered down by the "onlyfor" directives in the test files... usually to a single file. Therefore, just explicitly list the files we *really* want to run for this test mode. This makes it easier to see at the top level what tests will be executed, and to change that list temporarily while debugging specific failures. This means the "onlyfor" directive no longer has any purpose, and we can remove it. "onlyfor" was also the only used of the $MODE variable, so we can remove that too.

* Don't abbreviate ip(8) arguments in examples and testsDavid Gibson2022-06-151-3/+3
| | | | | | | | ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of "link show") is very handy when using it interactively, but it doesn't make for very readable scripts and examples when shown that way. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test/perf: Try sourcing maximum scaling frequency from cpufreqStefano Brivio2021-10-211-1/+4
| | | | | | | On most recent CPUs, that's a better indication of all-core turbo frequency, or non-turbo frequency, than /proc/cpuinfo. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
