Description
|
Currently PCF fonts in the core X11 font packages are shipped
in .Z compressed format. This saves only a little bit of space
(about 8 mb) and results in slower font access due to the need
to decompress on the fly and issues with the FreeType font
system, which has bugs in .Z compression. They should be
shipped uncompressed to speed up access and improve FreeType
font handling.
Size comparisions:
[1] Packages as installed, PCF fonts compressed .Z
[2] Packages as installed, PCF fonts not compressed
[3] Packages compressed with bzip2, PCF fonts compressed .Z
[4] Packages compressed with bzip2, PCF fonts not compressed

(So this actually saves a bit of space on the install media, where the packages
have bzip2 applied to the already compressed fonts, and bzip2 can compress the
raw files much better than it can try to squeeze more compression out of the
already compressed files.)
