@Octachron has a smaller repro case taken from Owl, that shows a regression in 5.1 even without domains. This repro case should be added to Sandmark. @Octachron could you post...

Excellent news, thanks! @tmcgilchrist the example of Octachron is a sequential Owl program which is available at https://gitlab.inria.fr/fangelet/ocaml-gc-regression-examples https://gitlab.inria.fr/fangelet/ocaml-gc-regression-examples/-/blob/main/analyses/gw_original.ml?ref_type=heads

@tmcgilchrist did you manage to add such examples to Sandmark? (I would be curious to see a pointer with performance results for those programs, that I could revisit in the...

Great, thanks!

@tmcgilchrist Thanks! I looked at the new sandmark webpage, and here is some random feedback. (I don't know if you are the right person to send this feedback to, but...
