[redirecting to ghc-users] I assume you mean the GHC profiler. It's normal when profiling any programs, Haskell or not, for timing numbers to vary. Memory allocation counts, however, should be stable across different runs. > Also a related q: why doesnt't the time spent in putStr show up? > You would have to rebuild your GHC libraries with the -auto-all flag in order to get cost centres attached to library functions (but this may defeat some optimizations).
