DMD compiles really fast. At the level of Go. As the reference compiler it always has the latest features. LDC compiles to fast code and only slightly lags behind the reference. It might even catch up soon. GDC compiles to fast code and supports many architectures in theory. It lags behind the most and architecture support also requires a ported runtime.
