Parsing is a tiny fraction of the time that a Web browser spends, and the various native resources are on the same level of complexity. TrueType hinting instructions from the 90s are of a similar complexity to the HTML 5 parsing spec.
> Go and fire up a windows 95 box, with 133mhx of pentium III goodness. THen make a VB6 app that animates boxes/shows images.
This will easily run at the same framerate on a modern Web rendering stack.
> Or, more easily, render a web page on the original raspberry pi-b, try and play video in a browser, do some sort of animation.
Browsers on the Raspberry Pi B weren't accelerated, due to various reasons including Broadcom having (at the time) the worst GPU driver situation imaginable. You should compare against modern accelerated browsers (by "modern" meaning "within the last 20 years on mainstream OS's").
> It lags like a fucker. Use py-game (you know python with its 50% "what fucking type is this?" tax) and you can run animations at 60fps.
Web apps have been able to run animations at 60 FPS for decades. (As an aside, the performance difference between CPython and native code is far more than 50%.)
