But I think most people don't care about it enough because they either never close Emacs and/or use it in server-mode where emacsclient is pretty much instantaneous. Can I ask why you don't like doing that?
So having things take time on start up is an annoyance to me (but I live with it, I was just saying that emacs is slower than VSCode)
I’m sure vscode would chew through resources during a heavy session, have you benchmarked more than just the startup of the application?
You're right: once VSCode is in memory I think it uses more of it. But that's barely nothing when compared to rust-analyzer (which emacs LSP uses too).
However, I also have many plugins installed, so it might be just that. I wonder if it is possible to install a separate instance of Emacs, then I would be able to test the performance without all the plugins and configuration.
