A fair comparison would be to build the libssh2 sfp_write_sliding[*] example
and run against the same server to see what maximum speed the current libssh2
can reach uploading SFTP. Comparing that to what libcurl can reach will give
us a clue about how much work we have.

Of course comparing with openssh or putty or similar is also useful.

It would make sense to upload a fairly large file and to use a server with
high latency (as high latency is more problematic for SFTP).
