this is on linux with zfs-fuse (since no other zfs implementation besides zfs-fuse has support for lzo at this time)
btw - here is some additional comparison - now with some real-world data. copying over some mysql database dir (var/lib/mysql) of size 231M gives: lzo | 0m41.152s | 2.31x lzjb | 0m42.976s | 1.83x gzip |1m21.637s | 3.26x i cannot tell if lzo and lzjb performance is really comparable, since zfs-fuse/linux may behave very differently to zfs/solaris - but in comparison with lzjb, lzo compression seems to give better results overall. btw: besides opensource lzo there is some closed source lzo professional which is even more optimzied. maybe sun should think about lzo in zfs - albeit those licensing issues. i`m sure that could be resolved somehow, maybe by spending an appropriate amount of bucks to mr. oberhumer. roland This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
