#+title: Performance
#+filetags: emacs-load
Increase the amount of data Emacs reads from a process in one go, default is 4KB, but some LSP servers produce responses up to 24MB.

#+begin_src emacs-lisp
  (when (boundp 'read-process-output-max)
    (setq ; process-adaptive-read-buffering nil
          read-process-output-max (* 24 1024 1024)))
#+end_src

Increase GC threshold to avoid random freezes on garbage collection.

#+NAME: gc-cons-threshold
#+BEGIN_SRC emacs-lisp :tangle no
  (setq gc-cons-threshold (* 1024 1024 256))
#+END_SRC

Set the minimum delay between LSP refreshes, should help with performance when typing really fast.

#+NAME: lsp-idle-delay
#+BEGIN_SRC emacs-lisp :tangle no
  (setq lsp-idle-delay 0.250)
#+END_SRC

Skip fontification on input, mostly helps with scrolling when Emacs cannot keep up withe fontification.

#+begin_src emacs-lisp
  (setq redisplay-skip-fontification-on-input t)
#+end_src
