> still getting irritated by Firefox taking forever to render a 10M email source code in plain text when it could do something smart and render/view only the viewport that's showing. How do you know what's supposed to be in the viewport, especially if the font isn't monospaced? You have to 'render' the entire thing at least once - at least to the point of measuring the dimensions of text (not a cheap thing) and figuring out where you have to force linebreaks. And whenever the user resizes their window horizontally or does various other things, you have to do it again. Your typical browser is already pretty good at this - not to the point some dedicated text viewers/editors are, but pretty good.

It's a monospaced font. Though even if it should have to render everything at least once, it should be in the blink of an eye --- at this point I'm almost convinced that getting a laptop with 10th gen i7 class CPU, 32G RAM and a RTX2060 graphics card to absolve myself of desktop performance issues was a mistake as it forces my to run Windows for flawless Optimus interop and does not get rid of desktop performance issues either. Maybe font rendering is not optimized enough or not accelerated at all, but a few million letters the most of them not even visible should be nothing on this machine drawing 100W and more but not performing much better at this specific task than my Haswell laptop from 2014.
