You don't tell on what system you try to build.

Parallel builds with processors with serveral cores scales nearly linear
even on normal disk , e.g. for the linux kernel or a wine build on linux. 
So pure processing power is all you need first.

Does your build setup use several cores?

Probably not worth ...
