Hello, I just started running my little 5 mbits mid relay on Pi3 on raspbian and all seems to be dandy, it picked traffic nicely, hovering around 700-800 total connections, its not unusual to see it pushing full advertised bandwidth during peak hours (with ~20-25% load on 1 core, multithread pls come already), tldr so far nice. Except with 3days uptime and 20 gigs of data relayed ifconfig shows 11 (eleven) packets dropped on eth0.
Personal opinion here:
11 packets dropped on 20GB of data sounds pretty small, and these packets might not even be from Tor. Literally any network service could have dropped those packets (ntp, ssh, updates, etc.) I wouldn't worry about it unless it starts to dramatically increase.
I agree. 11 packets dropped is literally nothing. I just pulled up some stats from one of my webservers:
packets:5436637 errors:0 dropped:4287 overruns:0 carrier:0
Server is performing fine, and the packet loss percentage calculated from those numbers is 0.07%. Yours would be even smaller. Don't worry about it.
