Rendering and parsing costs can be significant. In Microsoft Outlook for the web, I have had e-mails where it takes a full <b>second</b>\u200b between each keystroke. No, I haven't really investigated the detailed profile of where that cost was coming from. (It's
not open-source software, so why would I care.) One place I read it had to do with updating inline images. Hundreds of kilobytes of repeated content can't help though.</div>
