 1 | # speedInspectorRPI
 2 | > A docker image running speedtest every 10 minutes.
 3 | 
 4 | 
 5 | Intended Use: Run in a Raspberry Pi connected via ethernet to your main router.
 6 | 
 7 | > Note: When running on Raspberry Pi, just note that the maximum speed is limited by its 100 Mbit/s LAN adapter. The Raspberry Pi 3+ models comes with a Gigabit LAN adapter which [supports a maximum throughput of 300 Mbit/s](https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus/). 
 8 | 
 9 | Log the connection speed to docker logs and run in in a Raspberry Pi or your main machine.
10 | 
11 | ### Build docker image
