We use a variant of Lempel-Ziv called lzjb (the jb is for Jeff Bonwick). The algorithm was designed for very small code/memory footprint and to be very fast (single CPU can compress data at 150MB/s). When running a compression algorithm in panic context, you have a lot of constraints. --Bill _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
