I don't see how you could know that without reading the code.

Because the only update occurring is the changing of text in an input. Yet due to how React works it’s diffing a much larger tree.

Are you sure there isn’t a slow server request happening before the UI update? I would be very surprised that you’re regularly encountering web sites with noticeably slow React reconciliation. It’s difficult to make that slow.

The diffing is very fast. It would take a ridiculously large tree to start running up against the limits of v8.
