Just FYI, although zlib compresses better, it is slower as well.
According to Richard:

"This is particularly useful for jffs2 where significant boot time
speedups (~10%) and file read speed improvements (~40%) are seen when
its used with only a slight drop in file compression ratio."

AFAIK, the figures were related to Nokia N800. I guess for "desktop" CPU
this would not make such a big difference.
