[Haskell-cafe] Compilation time

[Christopher Allen]

Did you run it multiple times and get that output? Also you usually want
stack build.

My work projects use Stack and it'll *only* build my current project when I
run stack build (and be fairly fast) unless I changed the source, a cabal
file, or a stack.yaml.

If you did run it multiple times and got that output, is something touching
those directories between builds?
