[Haskell-cafe] Re: What is Haskell unsuitable for?

[braver]

At this very moment I'm struggling with fitting a huge graph of
Twitter communications into a Haskell program.  Apparently it gets
into a loop freeing memory.  As I suspected, JVM garbage collector got
more testing than Haskell at this scale; since not many people load it
up as much, it may be less tested.  The memory behavior apparently
requires tweaking -A and -H in some ways not right away obvious.  I'm
still new to Haskell, so perhaps with more profiling/tuning experience
it would have been easier, but so far Clojure is more predictable --
even though Haskell beats it on a smaller data set, I get a linear
resource consumption with Clojure while Haskell explodes.  I'd say at
this point it's not prime time for large-scale data mining on a single
box.
