My tab CPU reliably goes to 100% on specific websites |
||||||||||||||||||||||||
Issue descriptionChrome Version: 67.0.3396.62 (Official Build) (64-bit) OS: Mac OS X 10.13.4 What steps will reproduce the problem? (1) Visit https://engdoc.corp.google.com/eng/doc/devguide/cpp/styleguide.shtml?cl=head (2) Open the Task manager (or wait for the fan to spin up) (3) What is the expected result? Looks like a static web page, should quack like a static web page. What happens instead? Cpu goes to just under 100% and stays there. Please use labels and text to provide additional information. The obvious thought here is that this is a bug on that specific web site. But this has happened to me with other websites (specifically https://worldofsolitaire.com/, and less reproducibly subframe https://googlesyndication.com) and it started happening everywhere at the same time, leaving me to think that there's a reasonable chance it's chrome, not the underlying web sites. Also, when I got it from a Google website, I figured it was worthwhile filing a bug even if it did turn out to be a problem with the site and not chrome. (Sorry, Erik, since I'm not sure of the component, I'm ccing in someone who might be able to help :-} :-|.)

Somewhat worrisome variant: I had task manager running, not showing any spiking tabs, but the fan on my laptop was still going strong. So I brought up activity manager, and it showed a Google Chrome Helper at 99% CPU. That made me nervous (I was afraid it was malware hiding from the task manager in some fashion) so I just nuked the process from activity manager.

I second that bug on OSX solely (Windows is fine). Many of our customers are reporting 100% CPU usage on pages that use websockets.

Huh, interesting. I'm 90% sure that I checked on my Windows machine, and still saw 100% CPU. The fan didn't speed up because the machine already had beefier cooling, though. Websockets, huh?
