Research direction

Trace the page-loading and diff-rendering flow to find where diff rendering waits for the whole page. First reproduce or measure the current loading sequence, then make diff highlighting work with partial HTML in parallel; done means diffs appear before the full page finishes loading and rendering is measurably faster.

Description

enhancement

One of the main reasons for slowdown of diff rendering is we wait for the whole page to load before rendering diffs. But we can do it with partial HTML load as well. This will significantly improve the speed of diffs rendering.
