I’m running HA on Docker using the official docker image (v. 2021.1.3). I’ve had the Speedtest.net integration installed for a few months and I consistently see it report about 1/3 of speed that I can from the host OS. I finally got around to doing some actual tests. I ran the speedtestdotnet.speedtest service in HA and configure to run against a specific server. That pulled in a download of 352Mbps. I then immediately ran a speedtest from the host OS (Ubuntu 20.04) using the official CLI and it came back with 929Mbps. I did this a few times with similar results.
Is this expected? I understand that Docker could have a bit of networking overhead but I’m using “host” network mode and I have other containers that will download files much closer to the expected 900Mbps range.
