To use the GHC profiler, you need to compile your Haskell program with the -prof
flag and run it with the +RTS -p
option.
What does the output file look like?
The output file, usually named yourprogram.prof
, contains profiling information such as time and space usage for each function.
Can I visualize the profiling data?
Yes, you can use tools like ghc-prof
or hp2ps
to convert the profiling data into a visual format.
Are there any common pitfalls when using the profiler?
Common pitfalls include not enabling profiling during compilation or misinterpreting the output data.
