Bottom line is: FOSS has to do it's glyp rendering on CPU and either transfer the whole rendered text for each content change (more resource efficient) or has to upload humongous font atlases – good look if you want to render logographic script. So that's inducing a bottleneck.
The lesson here is: The graphics related resource constraints of 40 years ago never went away. They just bode their time, and now are rearing their ugly heads again.

So in conclusion: Of course a graphics system developed with the constraints in mind (because it wouldn't have worked otherwise) will perform a lot better on modern systems, than graphics systems designed toward the needs of 15 years ago.
