Richard The performance tests seem to be causing more confusion than I'd of liked. A baseline is established from previous performance test runs. There is a wiki page that may help: https://gitlab.haskell.org/ghc/ghc/wikis/building/running-tests/performance-.... Let me know if that's not sufficiently helpful.

Hi all,
I'm very confused by how to do performance testing.
I have a patch that seems to cause a performance regression. So I built the patch locally (`validate` flavor, with `make`) and then reproduced the regression. Good. Then, I make a small change, rebuild, commit, and then test. But now it seems that the baseline has changed. (This took some time to discover after seemingly non-deterministic results!)
So: how can I make several different commits, with different experiments, switch between them at will, all without changing my baseline? I do *not* have the magic "metric decrease" bit in my commit message. Or, at least, I didn't put it there.
Thanks! Richard _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
