Yes. When typing normally there is no slowness because you’re swapping one string for another.

But when pressing enter, pasting a bigger snippet, or deleting lines the slowdown is less noticeable. When you type a word, the deltas are tiny and it is easy to process for your brain. While the changes in multiple lines happen less often, so waiting a couple of frames doesn’t bother you much.

This is at millions of lines. With small files it is indeed too fast.
