I think linkedin is built with emberjs not react last i checked…

The problem with performance in wep apps is often not the omg too much render. But is actually processing and memory use. Chromium loves to eat as much ram as possible and the state management world of web apps loves immutability. What happens when you create new state anytime something changes and v8 then needs to recompile an optimized structure for that state coupled with thrashing the gc? You already know.

I hate the immutable trend in wep apps. I get it but the performance is dogshite. Most web apps i have worked on spend about 10% of their cpu time…garbage collecting and the rest doing complicated deep state comparisons every time you hover on a button.

Rant over.
