Would it be possible to use an IntMap instead of your OrdMap? Perhaps zip
your users with [0..] and key off the integer?
As a side note, I threw this package onto Hackage a while ago and may suit
your needs if you decide to move to something like IntMap:
http://hackage.haskell.org/package/EnumMap
It does have a performance hit over an IntMap, but I'm not entirely sure how
large it is.

I've supplied a profile report there. Since I load the graphs in memory and then walk them a lot, the time seems expected. It allocates a lot, though. The main graph type is
type Graph = M.Map User AdjList type AdjList = M.Map Day Reps type User = B.ByteString type Day = Int type Reps = M.Map User Int
and I walk it with M.foldWithKey. Folks said it's not strict enough, hence I tried to seq the step function, but to no avail so far. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
