Re: [Haskell-cafe] Performance difference between ghc and ghci

Roel van Dijk schrieb:

In general code compiled with GHC will be a lot faster than code interpreted by GHCI. You can also call compiled code from within GHCI, in which case you would hardly see a performance difference.

$ ghci -fobject-code compiles modules before loading into the interpreter environment. However expressions entered into GHCi will not be compiled with optimization.
