Haskell Collect Runtime of Function

I have a Haskell function which I need to collect runtime for over a series of inputs running 0 to 1,000,000 in steps of 100. Now, I would usually set ghci to :set +s, but I'm not really keen on manually running the script thousands of times.

I was wondering if there was any way I could code a Haskell function to return the runtime of another function.

Thanks Dario

There's the entire criterion package for doing this. As opposed to ghci, it runs the code with optimizations, too.

Start with the Criterion.Main module.

Criterion isn't well-suited to collecting data for each of a million data points, but it could be used that way.

I'd certainly trust its results way more than the results of a single timing for each of million data points. But it would take a while to collect a million results.
