...and this have been proposed by Matthias Clasen and Owen Taylor(Redhat/GTK); 
a binary mmap format for inclusion in the icon theme spec; navigated by name 
hashes IIRC. See thread "Caching icon theme information"(2004-10-13) on the 
xdg-list. There's (some) numbers and informative discussion in that thread.

As Lubos and many other says, is optimization discussions meaningless without 
numbers, but AFAIK compressing files is done in order to speed up access; to 
win disk-access at the cost of CPU time(since their time-scales live in 
different universes). There's some Quake engines that does compressing of 
data and they had positive _measures_(IIRC, long time ago). (It says nothing, 
but it's an indication.)
