They are the comparable, the impact of sshfs is minimal. I used the same SSH
options to conduct the test over a 10GbE link, and checked the speed of the
transfer using the NIC counters. I can't reproduce the tests right now, but on
top of my head, the numbers were:
- pure scp: about 130MB/s
- cp /sshfsmount/path/to/file /tmp/file: about 130MB/s
- rsync host0:/path/to/file /tmp/file: about 130MB/s
- rsync /sshfsmount/path/to/file /tmp/file: about 80MB/s
