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.
