Topic: multilinear timeouts

Rob Lewis (Mar 11 2021 at 11:37):

I just opened #6639, which speeds up a proof that's causing timeouts in CI. But I'm not sure if the slowness here is related to recent changes or if it's always been there. Any ideas?

I've run into the same issue in a different PR: https://github.com/leanprover-community/mathlib/pull/6045/files#diff-030c8b121453cb0be59dad5f7db3fe154f7bd17ad5ec67167535b9cb68400559

I think the definition is just on the edge of the timeout, and any change is liable to push it over.

Looking at @Jannis Limperg 's benchmark tool output, this commit added 20 seconds (25%) to normed_space/multilinear.lean

Which isn't proportional to the lines added, but the file was still slow before

Looks like https://leanprover.zulipchat.com/#narrow/stream/144837-PR-reviews/topic/.235672.20breaks.20timeout/near/223001979 is also having an effect, so I disabled some subsingleton instances in this file for further speedup.
