I'd like to third that. The main improvement for GF is that the build
is 5 times faster, 3 minutes with 6.8.1 instead of 15 minutes with
6.6.1, using -O2 with both. The compiled program runs 13% faster with
6.8.1.

I just finished a running Bluespec's regression suite on a version of
our tools compiled with ghc 6.8.1. The results were impressive on two
fronts:
1. All of our tests (almost 14,000) had the same behavior as with
ghc 6.6.1
2. Our Haskell code was roughly 33% faster (relative to ghc
6.6.1). It
seems that pointer-tagging made a big difference for our code base
(since, if I'm reading the release notes correctly, constructor
specialization isn't in yet).
We just wanted to take a moment to say that we were pleasantly
surprised by ghc 6.8.1 (so much so that we're going to try and use it
for released builds sooner than we would have otherwise planned) and
to thank everyone involved for the effort they put into it.
Thank you,
