[Haskell] Performance impact of GHC profiling?

[Howard B. Golden]

Hi,

I have wondered what the approximate execution (not compilation) performance 
impact (time, space) of compiling all Haskell programs with -prof and -fprof-
auto compared to regular compilations. For this purpose, I assume that I would 
run the executables WITHOUT +RTS -p or any other profiling option. In other 
words, I would make -prof and -fprof-auto the compilation defaults, but only 
use profiling runtime occasionally.

Does anyone have any data or benchmarks about this? Thanks.

Regards,

Howard
