I use iperf quite a bit in a remote support capacity.

It would be great if there was the option to enable an iperf server in the router itself, rather than having to find another PC to run it on, as increasingly, small businesses don't have any on-prem servers and secondly that doesn't provide definitively whether slow Internet access is the ISP or the router (or something it's connected to).

iperf binary on Linux is only about 68K.

Good idea! :idea:
