Unless you're in GIMP working on JPEGs, or doing some kind of MPEG video editing--or ripping audio (MP3 / AAC / FLAC) stuff. All of which are probably some of the largest files in most people's homedirs nowadays. 1 GB of e-mail is a lot (probably my entire personal mail collection for a decade) and will compress well; 1 GB of audio files is nothing, and won't compress at all. Perhaps compressing /usr could be handy, but why bother enabling compression if the majority (by volume) of user data won't do anything but burn CPU? So the correct answer on whether compression should be enabled by default is "it depends". (IMHO :) ) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
