Hi, Is there a runtime performance difference between a haskell program running under GHCI vs in its compiled form? Especially for a long running program - as in, ignoring the initial setup time. If I understand right, in both case tree reduction is what is happening and performance should be similar.
GHCi doesn't perform any optimizations, so whenever you're running interpreted bytecode there's a significant performance hit. However, if you compile the code, you can run the compiled/optimized version from GHCi as well. -- Live well, ~wren
