From 27.1 Emacs could be configured to use a native library (jansson) for json parsing, it helped LSP a lot. And now there is a new native-comp feature, where you can AoT compile elisp bytecode to native code with libgccjit, which improves Emacs performance in general. Anecdotally, a few months ago I wrote some Flutter on a potato laptop, NeoVim native LSP client + nvim-compe was borderline unusable. The vim-lsc somehow fared much better - albeit still choppy - even though it's written in vimscript. Emacs + eglot is the only combination that was smooth.
