Those numbers are averaged from 5-10 runs. So there is some slow down for some reason. It's not great and it's just 3%. But I hoped that 8.4 has more optimizations and will lead to better performance and not worse.

I don't see how 62 seconds rather than 60 is anything close to going off the rails. Did I read something wrong? This sounds more like a minor wibble.

Thanks for doing these tests! I have opened #14870 to make sure we don't
lose track of this. It would be interesting to bisect this to see where
we went off the rails.

This is a very interesting example which the Cabal file says is in the
public domain. In principle it would be a nice case to include in nofib,
although I suspect it has few too many dependencies.

Cheers,
