Using the Chrome Task Manager under "chrome menu" -> "More Tools" -> "Task Manager" I have found out that Macrumors.com is using >100% CPU. Even the Forum page that I am on right now typing this very post uses >100% CPU. I'm on a Mac OS X 10.13.5 and using Chrome Version 67.0.3396.62 (Official Build) (64-bit) which is the latest version.

I have more than 10 different Tabs open right now and none of them uses more than 1% CPU.

FWIW, I'm not seeing any MacRumors CPU issues in Chrome. I'm on KDE Neon Linux right now. Selection_009.png

If it was an extension wouldn't it be the extension that has 100% CPU. In the Task manager you can see that I only have 2 extensions: Adblock and 1Password with <1% cpu usage.

To make sure I deactivated all extensions and sure enough, the problem still exists:

It's like that any time you launch the page? Even if you exit out of the browser and start fresh (or perhaps even restart your computer)?

Since I'm at work, pitching in from the Dark Side with a Windows 10 screen capture:

yes, every time i launch the page. I tried: restarting browser, restarting mac, deleting all cache and site data, deleting all cached images. Nothing changed. Still 100% cpu usage.

It's ads. It's absolutely ridiculous.

Here's my activity monitor without AdBlock Plus, Chrome (and friends) uses like 237% of my quad core CPU (which has a total of 400% CPU available). With AdBlock Plus enabled, Chrome uses like 15% CPU. Both screenshots were taken on this page. Some ad is performing massive amounts of SetTimeout calls, looking at the Chrome performance monitor.

[doublepost=1527911517][/doublepost]Here's half a second of Javascript activity from this page. There has to be 200 script calls in there. Note that I have ONE highlighted in the middle.

Here's links to 3 of the files that seem to get called massive amounts of times.

It's interesting, while I haven't ran into this with MacRumors specifically (as I actually use Safari for the forums), since the last Chrome and/or macOS update from the last couple of days, there are pages that I visit and have open in tabs regularly that suddenly jump to 100% CPU usage in Chrome for no particular reason. Perhaps there's something more general behind it (like some issue with the latest Chrome and/or macOS update).

Chrome devs did a naughty:

MacRumors tabs are running at 100-110 according to Chrome task manager. The next nearest tab is 4.

If I have the website open my fan starts to pick up, and continues ramping until I close the tabs.

Is anybody else having this issue? This started 2 days ago. I hope this site isn't mining coin using my computer.

Probably more related to the latest update of Chrome than MacRumors in particular, as being discussed at Macrumors.com is using >100% CPU in Chrome
