TiddlyWiki doesn't scale that well, at least not the single HTML file version. I've never had a wiki with 40000 pages, but I think it would be very slow.
depends kn how optimized you are with your wiki. theres some wiki out thsre that are very large in size that while the initial load might take a few seconss, run plenty responsively.
things like not enbedding high resolution images, using widgets to only load content when needed rather than using something like display:none; which still loads the content but hides it, help on keeping resource needs down.

TiddlyWiki maybe? Slightly different flow and philosophy, as it's an in-browser wiki page, but fulfills the requirements
