Better yet, zfs send is decompressing, and then you're probably piping to gzip or lzop or something, and piping to ssh, so it got re-compressed and encrypted. Then at the receiving end, it gets decrypted, decompressed, and recompressed. ;-) While there are lots of reasons behind this, I think you'll find usually it doesn't matter. Only if you have really fast disks, or underpowered processor, or super-duper massive compression (like gzip, or worse... gzip-9) then it matters. Default compression is very fast and lightweight. _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
