Hello everyone, I have a Raspberry Pi 4B with 2GBs of RAM. I am trying to run all the *arr stack via docker containers(5 or 6 containers) but this causes my Raspberry Pi to lag very much. I could not use any of the stack’s web interface or SSH to the pi during the lag and to fix it I had to reset the pi.
I think it is because I have little RAM but it might also be the power supply because I sometimes get messages for undervoltage.
What do you think is happening and how could I fix it? Do I need to buy a more powerful device?
Thanks in advance.
Begin with listing what exactly you’re trying to run. I am running this myself, on hardware that’s worse than yours. You have to make choices more carefully
Do I need to buy a more powerful device?
Yes? You seem to have answered that yourself.
Run “free” and see how much memory is being consumed. And “top” as well (hitting ‘m’ will sorry by memory usage).
2gb memory is not nearly enough.
OK, I am trying to setup a swap partition right now to see if that will improve performance.
You can also just make a swap file, you won’t have to make partition that way
You don’t want a swap file on the SD card as excessive writes will kill it rather quickly.
While not untrue, it’s not entirely accurate. My entire arr stack runs on a 3b+ with just a gig of ram, with some still left over. It all depends on what, and how you run it
