Hmm... I can do the same under ntfs (at least the version that win2k and
winxp use). And savings are in the same order. Yup, I can live with
filesystem level compression.
I do have an observation, ignore real times as they only reflect how soon I
remembered to quit the pager. This is using cygwin.
Manual page with system level compression. Fed by man into gtroff(1) and
less(1):
address@hidden ~
$ time man fortune
real 0m5.155s
user 0m0.560s
sys 0m0.470s
Now that the same manual page from the cat directories, no system level
compression, gzipped. Fed by man(1) through gzcat(1) and less(1):
address@hidden ~
$ time man fortune
real 0m3.137s
user 0m0.410s
sys 0m0.570s
Notice that user and system times have changed but the total values are
basically the same. This gives me a very skeptical outlook on the matter.
