For what it's worth, an unbuilt Solaris workspace (containing only source files and SCCS files) stored on ZFS has a reported compression ratio of about 1.87. A large filesystem on which I keep primarily compilers (including several versions of the full Sun Studio install) has a ratio of 1.57.
It's not extraordinary compression, but it's pretty fast.... This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
