Do not hesitate to send what you have without waiting for the last details from Shardul's series to be fixed. You can simply mention the base series in your cover letter as explained here: https://github.com/multipath-tcp/mptcp_net-next/wiki/CI e.g. Based-on: <20261028-mptcp_penalise_send_v2-v5-0-32fb379ce117@mpiricsoftware.com> (Sashiko also supports b4's dependencies tags, but not Patchew -- it is fine to add both.)

But I'm going to try to push what I have today: it > might be better to work on improving the same thing. It took me a bit more time to fix the last details, but it should be usable now: https://github.com/multipath-tcp/mptcp-upstream-virtme-docker/blob/latest/PERF.md#tracking-regressions-locally There are many use-cases (based on previous work). The idea is that the regressions are found automatically by looking at the distribution over multiple runs. So it works best if you execute the tests a lot of time on a base branch, then check on top of your modifications (always under the same conditions). The whole suite might take a lot of time (1 to 2h), but it is possible to execute only some parts. Do not hesitate to suggest modifications or send PRs ;) Or tell me if that doesn't work for what you are doing. Cheers, Matt -- Sponsored by the NGI0 Core fund.
