I was a longtime Emacs user (and vim before that) and recently a project I was working on was far too laggy for me to actually work productively on in Emacs. It was largely due to me using various LSPs within Emacs -- the frontend was in TypeScript and the backend in Go, and inevitably things would grind to a halt on a 5 year old i7 MBP with 16GB of RAM.

Switched over to VSCode with as many extensions as I could find to get me close to my Emacs setup (including edamagit) and it, to my surprise, was actually very productive. I've been using VSCode now for 6 months and 15 year old me in the 90s is very mad at current me for selling out.

I have the exact same story. Multiple LSPs in emacs was too hard to manage and seeing as some of it was typescript, much worse than the VSCode experience. Edamagit has made a very good start at emulating magit in VSCode. Still use emacs for magit though.

It's probably too late for you :), but I use native-comp Emacs and it's blazing fast. At least lsp-mode+gopls is. I haven't gotten the chance to use this setup with Typescript's LS, but I've used gopls+clangd without slow downs.

Also, dang I miss coding in TS instead of Go.

I have the same experience. Being on master and nativecomp probably helps, and I also think eglot is tad smoother than lsp-mode. I am using 10 year old laptop, no friction at all with tsserver, elixir-ls or gopls. However I think the server itself is the biggest difference maker, because all hell breaks lose when I try dart/flutter even in a simple project. But to be fair, my neovim setup struggles with that too (nvim-lspconfig + nvim-compe).

I use Dart/Flutter LSP (lsp-dart) in Emacs all the time very successfully. “All hell breaks loose” sounds like maybe you have a project cloned or created but not yet `flutter pub get`’d, in which case I have seen it act like practically every token is an error.

Okay, I think I am hitting some weirdness in Dart-mode itself. But it's to do with something unrelated in my config perhaps, because now I can't reproduce this with `emacs -Q`, and my dart-mode setup itself is only `(use-package dart-mode)`.

Basically even doing something mundane like C-n/C-p in a dart-mode buffer takes up a lot of memory (~800mb), which causes very high GC pressure and everything visibly stutters. Here is the `profiler-report` output just now:

But it's not helpful beyond pointing out that `line-move` when called from `next-line` for some reason is memory intensive.

you could maybe try the two lines here (set the megabyte count, the third number, to your own liking): https://emacs.stackexchange.com/questions/34342/is-there-any...

LSPs and Large JSX file highlighting seem slow to me.
