* test: iperf3 3.16 introduces multiple threads, drop our own implementation ↵Stefano Brivio2024-07-251-1/+1
| | | | | | | | | | | | | | | | | | of that Starting from iperf3 version 3.16, -P / --parallel spawns multiple clients as separate threads, instead of multiple streams serviced by the same thread. So we can drop our lib/test implementation to spawn several iperf3 client and server processes and finally simplify things quite a bit. Adjust number of threads and UDP sending bandwidth to values that seem to be more or less matching previous throughput tests on my setup.

* test/lib/perf_report: Fix up table highlight for pasta's local flowsStefano Brivio2023-11-101-1/+9
| | | | | | | | | As commit 29269705239f ("test/perf: Small MTUs for spliced TCP aren't interesting") drops all columns for TCP test MTUs except for one, in throughput test for pasta's local flows, the first column we need to highlight in that table is now the second one.

* passt: Relicense to GPL 2.0, or any later versionStefano Brivio2023-04-061-1/+1
| | | | | | | | | | | | | | | | | | | In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas. Change licensing terms to the GNU General Public License Version 2, or any later version, with written permission from all current and past contributors, namely: myself, David Gibson, Laine Stump, Andrea Bolognani, Paul Holzinger, Richard W.M.

* test/lib/perf_report: Use own flag to track initialisationStefano Brivio2022-11-041-3/+6
| | | | | | | | | Instead of just disabling performance reports if running in demo mode. This allows us to use table functions outside of performance reports. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au>

* test: Move perf.js report file to $LOGDIR/webDavid Gibson2022-09-131-1/+2
| | | | | | | | | The tests generate a performance report in $BASEPATH/perf.js and hooks/pre-push copies it to the website. To avoid cluttering the working directory, instead put perf.js in $LOGDIR/web, since it's a test output artefact. Update hooks/pre-push to copy from its new location.

| | | | | | | | | | For demos, cool-retro-term(1) looked fancier, but several threads of that and ffmpeg(1) are just messing up with performance testing. The CI videos started getting really big as well, and they were difficult to read. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
