Does it influence load times ? (compressing programs at least) Disk
space is cheap, and I don't like waiting :)

Hi Folks:
On OS X, 10.6, I have been playing around with hfsCompression. I
can decrease the size of /sw/share/coot significantly:
% cd /sw/share/
% du -h -d 0 coot
180M coot
% sudo mv coot coot.1
% sudo ditto --hfsCompress coot.1 coot
% du -h -d 0 coot
31M coot
This can also be done with the libraries and binaries, and even the
whole of /sw.
It squeezed phenix down to 319 MB from 1.1 GB. CCP4's new footprint
is 562 MB, instead of 1.5 GB.
hfscompressing Xray data results in a factor of two space-saving.
The files still look the same from the point of view of the
operating system. You can in fact only "see" the compression using
commands like du or df.
