btw, just recent experience on ARM64 (X-gene board):bootstrapping 7.10.1 with 7.6.x took: ~120 minutes bootstrapping 8.0.1 RC2 with 7.10.1 took: ~446 minutes both run as: ./configure; time make -j8 It would be interesting to have the time for bootstrapping 7.10.1 with 7.10.1 too, for comparison.
boostrapping 7.10.1 with 7.10.1 took: ~212 minutes -- but this is not comparable directly with numbers above since for whatever reason haddock and doc is not build although I've used previous ./configure; time make -j8.
Anyway, parallel make itself is not good to use here since the build process may also contain some noise of paralellel make fixes and such.
I think more reliable benchmark may be simple build (single-threaded) of ghc-cabal here. I'll see what I can do about that.
