Subject: [Haskell-beginners] profiling :: memory allocation
Message-ID:

Hello,
I'm trying to figure out how to reduce the allocation rate in my program.
But I'm stuck with the profile report which has the top allocator to be
shown like this:
COST CENTRE MODULE %time %alloc
>>= Internal 20.5 22.6
I do not understand what it actually means? Can anyone explain to me or is
there anything I can do so it shows some more information (instead of
showing the bind operator >>=) ?
Thanks,
Konstantin

Since it's based on Arch can you use its repos?
There's an ArchHaskell repo with a few packages.

Arch directly provides ghc-7.10.1 and cabal-install-1.22.2.0 in its
repositories. You can use those.
There used to be a haskell-platform package on the AUR, but it's been
deprecated in favor of the five packages (ghc, cabal-install, happy, alex,
haddock)
Take a look here: https://wiki.archlinux.org/index.php/Haskell
