Question: RAM requirement for an exit relay
Hello! I would like to activate a local DNS resolver with unbound at the exit relays, but I am concerned about the RAM size with 1GB. On an example machine I have 2GB RAM and the exit relay occupies 400MB at 22.9 MiB/s according to the metrics. Does anyone have experience with such values? My smaller exit relays only have 1GB of RAM. Well, there is still the problem that simply trying it out is not possible. If I overrun the RAM and it comes to SWAP activities, then already on a local machine almost no access was possible. With a VPS this is a no-go. Kind regards! Olaf

Hi, My small exit relay 988625BFD9E9B23B35C590250407486F28FF8FFC runs on 1 GiB RAM VPS with local unbound recursive resolver. Memory usage looks like this: Memory: Real: 470M/861M act/tot Free: 110M Cache: 177M Swap: 317M/1049M In my expirience swap in general is a virtue, of course it might hinder the overall expirience on specific workloads. Also usually there is a way to access VPS if it has became unresponsive, like VNC. IMO you should simply try if you have non-network access to the VPS.

I have several 1 G RAM exits running unbound without a problem. They never seem to hit swap, either.

Hello ! Thank you very much for the large amount of replies. I have made a test and after less hours of activity I can confirm the low RAM consumption. There are no problems with 1GB. 'htop' reports 3,1% of RAM usage for 'unbound'. I will now reconfigure my fleet one by one next days. Kind regards ! Olaf Am 14.12.20 um 15:10 schrieb torix@protonmail.com:
hey, partly related to original question: I'm planning to set up a new exit. My very first relay. I'm planning to use a small SoC with 2GB ram. Something running on ARM like a raspberry pi. Is this feasible or even a good idea? Regards On 14 Dec 2020, at 15:10, torix@protonmail.com wrote: I have several 1 G RAM exits running unbound without a problem.

Hey, I run relays with less RAM and it works fine. A problem with a SoC might be that the hardware cant "help" with crypto stuff (but I am not sure, I've read that somewhere). Also, this sounds like you are planning to run an exit from home, which you shouldn't. Greetings On 15.12.2020 01:44, Amadeus Ramazotti wrote:
If you're going to run an exit relay from your home, just be aware that there is a > 0 chance that law enforcement will show up at your door with a warrant (or not) and seize your equipment. All of it, not just the Pi. Depending on where you live, they might seize you too.

Hello Amadeus! When you talk about a RasPi, I assume you mean a home location. Please read the recommendations. Never operate an Exit Relay at home! It will be expensive if the wrong people knock on the door. By the way, for an Exit Relay the bandwidth should already be 10MBit/s or better. Olaf Am 15.12.20 um 01:44 schrieb Amadeus Ramazotti:
