Ok ... NFS server: - FreeBSD 8.1-PRERELEASE-20100620 i386 - intel Atom 330 (1.6 GHz dual-core with HT --> 4-way SMP) - 4 GB RAM - re0: <RealTek 8168/8111 B/C/CP/D/DP/E PCIe Gigabit Ethernet> NFS client: - FreeBSD 8.1-STABLE-20100908 i386 - AMD Phenom II X6 1055T (2.8 GHz + "Turbo Core", six-core) - 4 GB RAM - re0: <RealTek 8168/8111 B/C/CP/D/DP/E PCIe Gigabit Ethernet> The machines are connected through a Netgear GS108T gigabit ethernet switch. I umounted and re-mounted the NFS path after every single dd(1) command, so the data actually comes from the server instead of from the local cache. I also made sure that the file was in the cache on the server, so the server's disk speed is irrelevant. Testing with "mount -t nfs": 183649990 bytes transferred in 2.596677 secs (70725002 bytes/sec) 183649990 bytes transferred in 2.578746 secs (71216779 bytes/sec) 183649990 bytes transferred in 2.561857 secs (71686277 bytes/sec) 183649990 bytes transferred in 2.629028 secs (69854708 bytes/sec) 183649990 bytes transferred in 2.535422 secs (72433702 bytes/sec) Testing with "mount -t newnfs": 183649990 bytes transferred in 5.361544 secs (34253192 bytes/sec) 183649990 bytes transferred in 5.401471 secs (33999996 bytes/sec) 183649990 bytes transferred in 5.052138 secs (36350946 bytes/sec) 183649990 bytes transferred in 5.311821 secs (34573829 bytes/sec) 183649990 bytes transferred in 5.537337 secs (33165760 bytes/sec) So, nfs is roughly twice as fast as newnfs, indeed.
