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.

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

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

Switch completion provider to =capf=, even though it should be the default, but just to make sure it. =company-lsp=
is what =lsp-mode= switched away from.
