I noticed that when I do compilation, installing some module, haskell
compiler uses only one processor (blue chart 1/4)? 1 of 4 on my laptop.
I've heard that Haskell Compiler is smart, so it could safe my time using all I have.
Is there a way to make it faster? Some configuration maybe.
There is a pic - processor graph is blue. Yellow - network. Red - hard-drive.
At that moment when screenshot was made it could use all processor time since it does not use either hard-drive or network.
You're looking for the -j
flag in GHC versions 7.8.1 and higher.
