I got even more encouraging results on another input - 5 vs 7 seconds:

Hi cafe,
Just wanted to inform you that I've been benchmarking my compute-intensive
stuff on ghc 7.0.4 vs 7.4.0, and 7.4.0 gave a large speedup - one program
that took 2.9s on a particular input is now taking 2.2s. This result is
repeatable.
So I encourage people to try out GHC 7.4.0. Some stuff
