Chrome huge CPU spike bug is still present

I am using the latest version of Windows 10, Chrome and NS deluxe. Please go to this site: http://www.neowin.net/ and scroll down and monitor the CPU usage. I had reported a similar bug few months back and guess what? Looks like they are having hard times fixing their own code or their quality assurance department was sleeping and testing this update. The same issue persists with other sites too.

Are you saying the problem is with that specific web site, or with Chrome, or with Norton?

Norton toolbar is the culprit, that's what I meant. If I disable Norton toolbar and go through that site then CPU usage will be normal.

This is  probably the wrong place, so please redirect if/as appropriate.

Some weeks ago I suffered similar problems with W7/Firefox and it transpired that the cause was a Norton security update, requiring a patch, which seemed to solve the problem.  I can't find that announcement, which is what I came on to the forum to look for in the first place, because two days ago I started to experience what looks like the same problem - the pc slowing down and CPU usage showing at 100%, for no apparent reason.  At such times, the Resource Monitor shows a lot of svchost.* activity, which may be a coincidence, of course.

Any ideas, anyone?

Thanks,

Ian

Here's the CPU usage by Chrome when Norton toolbar is enabled. I should have uploaded this before

Re: Chrome huge CPU spike bug is still present

When I used Windows 7 after a fresh install I had faced similar issue. Go to Add/remove programs and check if this patch is installed: Windows6.1-KB3102810-x64 if it's not installed then you can install it from here: https://www.microsoft.com/en-us/download/details.aspx?id=49540 That patch fixed that high CPU usage by svchosts memory leak issue. Let me know if it works

Re: Chrome huge CPU spike bug is still present

Again, may be the wrong place/different issue, but for the record, I have Norton Toolbar disabled (and it'll stay that way until ID Safe is available thereon!).

Edit: this post was made before I saw the post above, for which thanks.  I'll check out the suggestion.

Thanks,

Hello lan

Re: Chrome huge CPU spike bug is still present

Hi again floplot,

Thanks for that.  I hadn't seen the announcement, but I'll check it out.  I note that I should be running FF48.0.1 to use IDS, but I'm on 47.0.1 and told it's up to date,s I'll have to check that out, too.

Meanwhile, back on the current issue, I installed the named KB file in the middle of a high CPU use event and it seemed to cure the problem, bringing CPU use right back down.  I'll monitor for a few days before saying it's fixed, though.

Thanks again,

Ian

Re: Chrome huge CPU spike bug is still present

Just restart your computer after installing that patch. That patch will fix that memory leak issue aka high CPU usage by svchost.

Re: Chrome huge CPU spike bug is still present

Thanks, shellcoder,

That's exactly what I did, though could it have been a coincidence that the computer reverted to normal service after the installation?  I attach a couple of screen caps, one showing the results of a search for KBetc before and another after.  Apart from the presence of the update files, I can't see any difference.  I also enclose screen caps of "normal" and excessive CPU activity, all for information.  I'm afraid these don't enlighten me at all, but may provide clues to people who know what they're looking at!

If you search, you will see that Mozilla has some issues with the 48 release and stopped distribution. I have one system with 48 and the other is still on 47.

Re: Chrome huge CPU spike bug is still present

Hi again,

I didn't mention it, but the problems outlined above were happening on my laptop, as I was away from base.  I'm now back at home and on my PC, which has suddenly started behaving like the laptop, ie high % CPU activity.  It hung when I tried to copy files from a USB device and I had to hold the start button down to get the machine to switch off after the screen showed logging off, then shutting down, but it didn't. 

It's since restarted and shut down OK but is still showing high CPU usage.  It was OK when I left a week ago and the only difference is a week's worth of Norton updates, one of which required a restart. I did check that the KB3102810 update was present and it was, so any ideas, anybody?

Thanks,

Ian

Re: Chrome huge CPU spike bug is still present

Well, that patch solved that issue on Windows 7 Pro laptop. It's still working fine. Looks like only Google can solve this problem. I would recommend upgrading to Windows 10. It's a lot faster and better than 7. I have Windows 10 Pro installed on this laptop and 7 on the other. I would never go back to 7 though I prefer the UI of 7

Re: Chrome huge CPU spike bug is still present

I'm pleased for you, shellcoder, and am happy that my own laptop still seems to be OK.  I can afford to take risks/experiment with my laptop but I can't afford any mistakes on my PC, so your suggestion of upgrading to W10 was not welcome.  Haven't you seen this thread?

http://answers.microsoft.com/en-us/windows/forum/windows_7-update/follow...

Strangely (or perhaps not so strange), the fix for this problem, which I'd had to deal with, also involved KB3102810!  I'll talk to the people over there and see if they've anything to contribute.

Re: Chrome huge CPU spike bug is still present

Here's the same issue with Facebook too: If you go to Facebook and search for a person and click 'See More' then keep scrolling down and down. Norton CPU Hog toolbar will cause CPU spike again. It's been so many months we have been facing this issue. One thing that really wonders me is, did they hire some crappy programmers who can't even fix bugs in their code even after months?

Re: Chrome huge CPU spike bug is still present

Hi all,

I've been running this issue on the MS forum as well, having spotted a common thread - the KB3102810 update, which features in a solution for a W7 update problem.

The advice I'm getting there is to ditch my comprehensive suite approach and go for a simple AV solution, which I'm going to try on my PC as it's still giving me problems.

You should look closely, it's more than 40% on my Core i7 6700HQ.

What I saw in the image above is Chrome entries for 11.1% and 6.8%. Far from 40%. The 42% is the total CPU usage. You need to sort the column by CPU usage to see what is using the other 25%.
