There are over 3B devices using Chrome as browser. 2.5B of them are either on Laptop, Smartphone or Tablet. Average Opened Tabs is still under 5.

As much as I want them to optimise for memory usage. Taking less CPU time for rendering is extremely important for battery.

Not to mention faster site is noticeable. And that is what sells. Chrome was faster than everything else when it launched. ( May be apart from Opera )

How do you know that isn't just measuring that most people keep to 5 tabs because otherwise everything grind to a halt. That's about how many tabs my wife's old Chromebook can handle before she has to start closing old tabs.

I am assuming it grind to a halt because it is CPU bound and not Memory bound? In that case the premises of CPU optimisations are not important would be, inaccurate?

In reality it is complicated when we have extra CPU cycle to burn developers tends to put fancy new things. Which is basically what andy giveth bill taketh away.

Probably "everything stops" because tabs consume too much memory and OS starts swapping data to disk.

It's because she runs out of memory and it starts swapping, I check the task monitor or whatever it is called in chrome. Some of the AdBlock extensions are taking up ram as well.
