>Hi There

>This is a pretty interesting topic. I have been running a Rasp Pi 3 based relay since August this year. By now, I am up to about 1,300 incomming and outgoing connections, and a max of >about 21mbps. This is about 50% of the max. upload speed. Consensus weight is between 3,000 and 6,000. The CPU is running at 20% max. However, my local ISP disconnects me after 24 >to 36 hours. From my point of view this is the only disadvantage.

My experience is bad, the relay is not taking off at all, I have consensus weight of 19 and am sending less than 20 MB every 6 hours despite having bandwidth measured by Tor of between 70 and 120 KB/s. The total up bandwidth I have in ISP connection is 1.5 mbps and this is probably the issue. I also run this on Pi 3. I did, however, get a stable flag after 5 days, and have had it since then. My IP is dynamic and did not change in these 5 days or in the 4 days that passed since I got the Stable flag. My relay nickname is ZG0.

Based on your experience I think your are doing fabulously well for a home relay, and that what really counts is the ISP bandwidth, and the Stable flag does not have much to do with how much traffic you get. Moreover, your 20% cpu util confirms my opinion that Pi is the perfect, most cost efficient way to run a relay and that running it on a larger computer is a waste of resources and money (up to the point Raspi chokes which we are yet to discover J)

Moreover, clearly Pi’s cpu power will never be the bottleneck, only its memory size. You have a total of 1GB of memory on your Pi 3, what’s your memory utilization?  about 513 MB 

What’s the total traffic the Pi sends every 6 hours (reported in the Tor log file /var/log/tor/notices.log and, for the previous time window, in /var/log/tor/notices.log.1)? 

About 19 GB in the last 6 hour period, with a total sent 2671.53 GB and received 2625.31 GB. 

What’s your relay’s nickname? Balbea16
