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.

    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.

          File and partition get just as many writes. In fact files are better because you can create a second file on a different location and move the swap more easily to try to keep the writes spread across the card.

          So does a swap partition. I just meant that’s an option as an alternative to it. But now that I think about it, not enough RAM wouldn’t cause performance issues anyway, it would just cause random applications to stop working.
