This is not a good way to test network throughput. I'm not sure how scp
protocol works, even if you disable compression and encryption, it may
be doing other work like computing checksums, etc. Also it is reading
and writing data to disk, so depending on the speed of your disk there
will be overheads.

I would recommend you use specific tools like iperf, which generate
data on the fly.
