The execution time and CPU usage is almost the same.
However the C++ version requires 305 MB, the GHC version 617 MB.
I wonder how much of that is due to lifting (i.e. laziness).

Performances are the same; but I'm not sure if this removes all laziness.
I have changed
ins t (k,x) = insert k x t
to
ins t (k,x) = k `seq` x `seq` insert k x t
