That's an interesting alternative to rsync, scp, and ftp, but doesn't help with zfs send/recv which is where the none cipher really shines. Without the none cipher, SSH becomes the bottleneck limiting transfers to around 400 Mbps on a gigabit LAN. With the none cipher, the network becomes the bottleneck limiting transfers to around 920 Mbps on the same gigabit LAN. This is between two 8-core AMD Opteron 6200 systems using igb(4) NICs. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
