Repo is private. I have 2 "main" files. One for a desktop build and one for a mobile build. A lot of the project is shared between the two. The differences are in the nested pages — following the elm-spa-example, I have individual modules under a Desktop/Pages and a Mobile/Pages directory. There are more pages under Mobile/Pages because the UI is divided up more.

This is the state of affairs after doing our best to refactor things. I have reduced the module count by about 100 and that has helped (but it was pretty painful and clearly the module count will increase again as the codebase grows).

Build from scratch

time elm-make client/elm/Main.elm --output=/dev/null
Success! Compiled 297 modules.
Successfully generated /dev/null

real	2m3.696s

Build after touching most imported module (seems to be worst case for incremental)

Despite trying to capture the best and worst case like this, we also see compile times much longer than this quite regularly but I cannot spot any pattern.

Note that we actually use windows. I have compiled these stats on a linux vm just to get consistency with others. The times are, however, quite representative with what we see on windows using elm-gulp as well.

SPA at work. I'm leading the frontend on this rewrite.

tl;dr

Types	RTS Opts	Compile time	Artifacts size
Yes	-A512M -H128M -n8m	3m7s	91M
Yes	-s	6m14s	93M
No	-A512M -H128M -n8m	1m22s	13M

For the last one I removed all type declarations apart from our main function. I also had to remove a few files as I kept running into an issue with the type inference algorithm of elm-make: Unable to generalize a type variable, it is unranked.
