Well, for the most part my question regarded the slowness (or lack of)
gzip DEcompression as compared to lz* algorithms. If there are files
and data like the OS (LZ/GZ) image and program binaries, which are
written once but read many times, I don't really care how expensive
it is to write less data (and for an OI installation the difference
between lzjb and gzip-9 compression of /usr can be around or over
100Mb's) - as long as I keep less data on-disk and have less IOs to
read in the OS during boot and work. Especially so, if - and this is
the part I am not certain about - it is roughly as cheap to READ the
gzip-9 datasets as it is to read lzjb (in terms of CPU decompression).
