[llvm-dev] [help] How to speed up compilation?

[Sunghyun Park via llvm-dev]

I'll try those guys! Thanks for advices, all!

Btw, I have a question.
Personally, it feels like compilation become much slower than previous
versions after adopting 'cmake'.
Is this natural when we adopt cmake or are there other big changes on build
structure?
I'm not that familiar with huge system like llvm yet, so I want to catch up
how professionals design their system.
