[Chrome] CPU Usage way too high with Chrome

Chrome Version 25.0.1364.68 (Official Build 180609) beta-m
running on Windows 7 (64-bit)

I've noticed recently that Chrome is running "hot" with a very high CPU usage. With Chrome idle it fluctuates between 15% and 50%. This shows both in Windows Task Manager as well as Chrome's internal task manager where it reports about a 20% or so CPU usage with nothing going on. The high CPU reported here occurs with only a default tab open and showing either Google.com or default new tab with recently closed pages so it's not some content on a web page causing it.

If I launch Chrome with -incognito or --disable-extensions, I see no difference and CPU utilization remains the same so it doesn't appear to be any extension involved.

Launching FF on the same computer with just FF's one default tab results in CPU utilization below 5%.

Any suggestions for resolution or further troubleshooting?

That's a Beta version.

There's an obvious reply.

Other machines at home and work running the same version of Chrome don't experience the high CPU. Some of those Chrome installs are also synced to the one that was showing a high CPU and they were fine.

Late yesterday I uninstalled Chrome and re-installed the same beta version. Once resynced and the same extensions were running, the CPU was no running up to 50%.

Not sure it is Chrome. Could be something else on your system.

Check its "flags": chrome://flags

Chrome's internal task manager shows only Chrome and it was showing 20% CPU for the Browser process. The below picture is Chrome's internal task manager and on this machine shows the Browser task using 2% vs the 20% I'd see on the other machine.

Anything specific that might have caused high CPU? I didn't change anything there from the defaults but maybe something else did?

No, there is no specific advise. Just play with some options (flags) there and see if it helps. The list includes lot of computer specific and graphic acceleration related options. Just keep records (for yourself) of what you're doing there to be able to return it back.

I have the exact same problems
25.0.1364.84 beta-m
on Windows 8 (64-bit)

CPU usage (in both the system and internal task manager) fluctuates between 15-20% on a 4 logical core machine, even if I launch chrome with only the new page screen right after a reboot. Moreover, the (internal) task manager is reporting that all the CPU usage is coming from the main browser thread.

This has happened to me before. I uninstalled and reinstalled, and the fixed the problem until it started acting up again. Obviously it's not practical to reinstall chrome every time this starts to happen. I have tried non-beta builds. I have disabled every extension and plugin. I have reset all the flags to their defaults and played around with them besides. I have cleared all browser data. I have disabled my antivirus software. None of it helps.

"chrome://profiler/" shows that "Chrome_IOThread WorkerThread-*" has the greatest run time, with "Chrome_IOThread PresentThread #* Browser" coming in second

Any advice would be appreciated
