I have not observed such lags before on GNU/Linux, so so= me idea what I
may be doing wrong?

I know Eli uses MS-Windows fre= quently, so, any hint?

Try usin= g c-ts-mode instead (assuming this is Emacs 29 and it was
built with tre= e-sitter)=2E

And if you cannot = use tree-sitter, then try this:

(setq jit-lock-stealth-time 16) (setq jit-lock-defer-contextually t)
(setq jit-lock-stealth-load 20= )
