Hi,
On a mpc8347 board it's ~12% faster at decompressing the uImage (165ms).

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.
