 Joakim> Thanks, question: How does this compare with your lzo uncompress?

Lzo is still slightly faster, but it only about ~5% (60ms). This is at
400MHz with very slow flash. With slower cpu/faster flash the difference
would probably be bigger (it certainly was when I compared with zlib
before your optimization).

I can rerun that test, but first I need to figure out why 2009.11-rc1 is
more than 1 second slower than 2009.08.
