I disagreed. I don't usually notice rendering performance problem. I only noticd Javascript performance. But that's because I have 1,000 tabs open, and each tab is running 100 Javascripts due to modern websites desired to be dynamic and 'animating' all the fucking time. The way to solve this is NOT to make Javascript faster. The way to solve this is also NOT to force websites to run few numher of Javascripts at the same time. The way to solve this is to virtualized all the tabs. In other word, tabs that are not visible should be unloaded (allow the user to right click a tab and "Keep This Tab Loaded"). This saves on CPU usage and RAM usages. In summary, rendinger performaces is in the milliseconds, compare to running 10,000 Javascripts, which is in the minutes.
