J, TNX for the recommendation. Just used a spare one. Temperature dropped to 41 C. Didn't like the noise, because it's running permanentely. However, you are right :-)

Well I do suggest that you get a set of Pi heat sinks on ebay for $0.70 (including postage from China, adhesive and sinks for all 3 chips on the Pi). And if you are as extravagant as I you will even shell out an additional $1.20 for a Pi case.

OK then let me summarize. 1. You are running a Pi from Cologne, at 21 mbps (measured) peak, 900 kbps (measured) average utilization by Tor, with 1300 connections.2. Your Pi is under-utilized, probably limited by your ISP’s peering with those to which DirAuths are connected. 20% CPU utilization, 50% memory utilization. 3. Given that part of the memory is used by Linux kernel, and that the PI Ethernet interface is nominally 100 mbps, the Pi is probably able to sustain up to 3000 connections. Bottom line: the $35 Pi is a killer and running a Tor node with up to 3000 connections on another computer is probably a big waste of money. Comments welcome.

I meant aluminum heat sink, not a fan Heat sinks do not make noise, they are flat pieces of metal with rib structure for improved heat radiation. You glue them on the chips that tend to become hot as they crunch your Tor relay traffic. But hey, whatever turns you on :)

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.

For a home based relay, is that good, bad, or just average? Is there a chance for me to get a stable, or even guard flag? What are your experiances? Mike
