React is very sluggish when updating many elements at once, for not very large values of "many". With some regularity, I've debugged React+MobX jank issues where a bigger update, such as switching from one panel to another, takes upwards of 200ms on a mid- or low-range machine.
None of this is perceptible on our beefy dev boxes, which is why I think people disregard it, and why the modern webapp experience is so miserable for the average person.
