Another things to note about 8.2 build times is that a bulk of the time is probably being spent during the linking phase. This is because GHC 8.2 has switched over to split-sections by default, but unfortunately, old versions of the BFD linker take a long time to link code that uses split-sections (see the discussion at [1]). There is ongoing work (which should hopefully land before the final 8.2 release) to use gold instead of BFD as the default linker when available, which will reduce linking times dramatically.
