"scp" is definitely not suited for testing. Besides the encryption the
file-system access and the SSH protocol will limit the throughput.

There are a variety of tools in "pkgsrc" which can be used.
Here are a few examples:

        benchmarks/netio
        benchmarks/netperf 
        benchmarks/ttcp

I've used "ttcp" in this case with the following options:

Receiver:
        ttcp -r -s -b 131072

Sender:
        ttcp -t -s -b 131072 -l 32768 -n 8192 <target host>

The benchmark requires access to port 5001/TCP on the receiver.

        Kind regards
