Feature: Benchmarking without a reference? about rich-bench HOT 4 OPEN

no that's not currently supported.

Just so I understand, would you run all the benchmarks with no comparison function? You're only interested in min, max and mean?

I could change the code to look at the length of the tuple and not run a comparator test if there isn't a second benchmark defined. It would get tricky if some did and some didn't (with the table output)

Yes that would already suffice (perhaps trimmed mean / median).

What I had in mind is a workflow as offered by frameworks like e.g. criterion.rs in Rust. By default they just measure the test cases as defined. Internally they also offer comparison to the last execution or also explicitly saved snapshots. This can be helpful to e.g. benchmark before/after an optimization or refactoring for comparison. Or to track the longer term performance development of a project to see how things evolve over time when e.g. dependencies change (by committing these snapshot files into git).

This internal diffing isn't super important though, because a lot can already be achieved by doing manual before/after or snapshot runs. Thanks to the beautiful output in the form of a table, once could for instance simply take the output and append it to some benchmarks_log.txt committed to git, which would also nicely document the performance evolvement of a project.

ASV (airspeed velocity) might suit your requirements, it has a database, web UI and a ton of other tools. Some big data science libraries (iirc Pandas inc) use it.

Yes indeed, ASV is pretty nice! In certain use cases something more lightweight like rich-bench is a nice alternative though due to its simplicity.
