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.
