I'm using Doom Emacs, which is taking a lot of Memory if my browser is opened with 10 tabs. What can I do to reduce amount of memory being used, without sacrificing the packages?


My config.el is as

  • Why do you believe that Emacs using 240.8 MB of RAM / memory is taking up too much of your system memory? That looks pretty low to me assuming your machine was built in the last 10 years, that is ... Is there something about performance when using Emacs that is causing you concern?
