Hi Jeff
I think if the 3B+ actually had gigabit ethernet, it would show up in the iperf column. Compare it to the Macbook Air:
It looks like the new Raspberry Pi 4 has actual gigabit ethernet, so maybe you should update your blog post to recommend that?
Thanks for the blog post. I’d read Troy Hunt’s article about Pi-Hole a while ago, and initially I set it up running in a docker container which was a bit flaky. I bought a Pi 3B+ and set it up last night. Was my first Raspberry Pi experience and overall I am impressed with the kit! I might buy some more of them to play with.
