One second of delay before the first window-full is displayed? This is like infinity. And you didn't account for the time to take buffer-string of the entire buffer (which involves allocating a large chunk of memory), then encode it in UTF-8 (which needs to allocate another chunk of memory), and pass that to tree-sitter. If that's what the current interface does.
