What version of GHC are you using? There have been some significant improvements like https://phabricator.haskell.org/rGHCb8fec6950ad99cbf11cd22698b8d5ab35afb828f, that only just made it into GHC 8.4.
I did in fact notice a very nice speedup in 8.4, this explains it. Finally I know who to thank for it! Thank you very much for that fix, it really makes a difference. Are there more goodies in the 8.0.2 facebook branch, or have they all made it into 8.4? As loaded modules seem to consume a lot of memory, I've considered trying GHC.Compact on them, but haven't looked into what that would entail. Have you considered something like that?
