The easiest way is to disable the scripts, which you can do by appending ?slow-browser to the page's URL, as in: http://www.whatwg.org/specs/web-apps/current-work/?slow-browser > One good way I have found would be to cut the whole page into several > parts (one the server side, what is already done in the multi-page > version) and to launch several workers.

As others have noted, the slowness turns out to not be parsing, but to be a bunch of scripts that are doing various things such as adding the sidebar annotations, setting up the <dfn> cross-references, and generating the short table of contents. Plus, since browsers don't have thread-safe DOM implementations, we actually can't expose the DOM in workers.
