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.

      I saw that it uses about 1,3 GB of memory. This means another 700MB remain. Because of this, I don’t think the cause is the memory. Also, I forgot to mention that I am also running qbittorrent for downloading, gluetun for VPN, and jellyfin and jellyseerr.
