I am using Next JS too. Were you able to limit your RAM. I have 8GB of RAM. I switched from Windows 11 (which used around 4GB of RAM in idle state) to Ubuntu 22.04 (which uses 1.8GB of RAM in idle). Running npm run dev consumes the rest of the RAM I have. Later, I looked at system monitor in Ubuntu, I see swap memory also being used around 3GB. I thought linux would help me. But that does not seem to be the case.
