ndnop5 is now running with iat-mode=2. I will keep an eye on CPU usage as I understand this is expensive.

Thanks for making this change. I opened a ticket to make the matching change in Tor Browser in https://bugs.torproject.org/20837#comment:1.

I wouldn't expect iat-mode=2 to use a lot of CPU. It's expensive in the sense that it "wastes" bandwidth by adding extra padding and delays.
