Hey all,
I just released the tool profiteur [1]. You can use it to visualise GHC `.prof` files in a tree map -- I think this makes looking at huge `.prof` files a lot less unwieldy. More information can be found in this blogpost [2].

Hi, Great! The way profiling output analysis is now is a huge pain in the ass. I'm very glad to see that something new is up. I did want to try it but I can't get it to run: on ghc-20140225, aeson fails to compile so that doesn't work. I did manage to compile it with 7.6.3 but after trying to run it on a profiling output I had lying around, it failed with: /home/shana/programming/yi/yi/yi.prof: Failed reading: takeWith You can find the file in question at [1] (~1.4MB). I'm most eager to try this out so it'd be great if you could have a look. Are there plans to support on-line rendering? I find it very useful to be able to see the profiling output as the program is running. Previously I ended up having to periodically (~5 sec) generate the postscript file and then have the postscript viewer watch it for changes. It was very cumbersome but it sometimes worked. It'd be great if your software could do something like this! Are flags other than -p supported? I know that it's possible to get different profiling output, such as on size of allocated structures &c. [1]: http://fuuzetsu.co.uk/misc/yi.prof -- Mateusz K.
