@shrike were you looking at wakeups last year? 500 wakeups per second seems high, although I'm not sure where exactly that number came from.

500 wps is a lot but it depends on what you're doing in the browser. It would help to get a chrome://tracing trace file from the browser when it appears to be running slow.

Which type of tracing I should generate, 'Web developer' one?

I usually go for manual and then select all of the options.

@kenorb: Hey, would you mind replying as per comment#4 ?

Appreciate your help.

Thank you!

I think I won't be able to provide more tracing data about the performance, since I've installed bunch of extensions across my over 20-30 people profiles (which I'm using to group my tabs) to limit all the CPU background processing, which is The Great Suspender (I had already Adblock Plus to block some certain ads), so the tabs are automatically "killed" when unused for over 1h. So I think it helped with my performance issues. And I think my issue was related to large amount of tabs being open and Chrome which was processing all the JS code constantly and adverts across all the unused tabs. Before I've installed the extension, Chrome was killing my machine, in other words the problem was like in the attachments.

I think without any implementation of feature which blocks the background processing (JS, gif and other animations) for unused/minimalized tabs (like The Great Suspender does), there is nothing which can help here. I think it's just a design issue and how I used to work with large amount of tabs.

So I think this issue can be closed.
