how to use scala internals to compile source faster than fsc (fast scala compiler)

Question

fsc (fast scala compiler) is faster than scalac. but during TDD cycles i consume 3 seconds to compile sources over less than 1s to run my tests.. suggestion to reduce compile time near 0?

obviously, buy a faster computer is not an answer :)

i mean use some scala internals to compile source faster as possible
