Nope. I know LZJB is not LZO, but I'm starting from a point of saying that LZO is specifically designed to be super-fast, low-memory for decompression. (As claimed all over the LZO webpage, as well as wikipedia, and supported by my own personal experience using lzop). So for comparison to LZJB, see here: http://denisy.dyndns.org/lzo_vs_lzjb/ LZJB is, at least according to these guys, even faster than LZO. So I'm confident concluding that lzjb (default) decompression is significantly faster than zlib (gzip) decompression. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
