I don't even have a problem with 7.4.1:
$ for ghc in $GHCS; do echo $ghc; time ./hskahan-$ghc > /dev/null; done;
$ time ./ckahan > /dev/null
We have an unpleasant regression in comparison to 7.2.* and the 7.4.* were
slower than 7.6.1 is, but it's all okay here (not that it wouldn't be nice to
have it faster still).
Are you on a 32-bit system?
