Can compile times be improved from around 10-40 minutes?

[Wizek]

On my machine jsaddle-dom takes quite a lot of time to compile.

It usually hangs after this step the most:

Configuring jsaddle-dom-0.9.2.0...
Building jsaddle-dom-0.9.2.0...
Preprocessing library jsaddle-dom-0.9.2.0...
[  1 of 599] Compiling JSDOM.Types      ( src/JSDOM/Types.hs, .stack-work/dist/x86_64-linux/Cabal-1.24.2.0/build/JSDOM/Types.o )

Then the RAM consumption just keeps rising, till around a 2-5GB peak before the modules continue building.

• Any idea what could be the culprit?
• Could it be the case that GHC is having a hard time processing a package with 599 modules?
• Or do other packages with similar module counts compile quicker?
• Is there something relatively fundamental at play here?
• Or could there be some low hanging fruit to speed this up?
• Has there been any efforts to reduce or profile build times so far?
