Chrome is arguably the fastest performing browser available today, but that goodness comes at a cost It's Time To Break Up With Google Chrome It's Time To Break Up With Google Chrome As a big fan of Google Chrome for a long time, I finally decided it was time for us to break up. It came down to overall performance, customization, and extensions. Read More . In order to be that fast, it has to use more CPU than other browsers are willing to use — and more CPU usage means more battery drainage.

That’s just one of the many reasons not to use Chrome on a MacBook 10 Reasons You Shouldn’t Use Chrome on a MacBook 10 Reasons You Shouldn’t Use Chrome on a MacBook Chrome is, for many people, the first thing installed on a new Macbook. It makes sense: in its early days Chrome gained a reputation for being lightweight and fast. Read More . Its heavy dependence on CPU means that it can impact the performance of other applications and cause your fans to be louder as they try to expel the extra heat. But what can you do?

1. Keep fewer tabs open. In Chrome, every additional tab is another process on your system, which means that each open tab increases the burden on your CPU. Tabs that are heavy on JavaScript and/or Flash elements are particularly bad.


2. Remove unnecessary extensions. If your Chrome is experiencing unusually high CPU usage, the usual culprit is an extension gone amok. One of your extensions might be poorly coded, or it might just have a bug, but in either case, you should remove them one by one to see if it helps.

Note that an extension could use CPU even when disabled, so we recommend actually removing them to make sure.


3. Disable hardware acceleration. The hardware acceleration setting allows Chrome to share heavy processing loads between your CPU and your GPU, but it doesn’t always work well. In fact, sometimes it causes Chrome to use more CPU. Try disabling it and seeing if that helps.

High CPU usage could be the last straw that finally drives you away from Chrome Don't Give Up on Chrome Until You've Done This First Don't Give Up on Chrome Until You've Done This First If you're contemplating ditching Chrome and switching to Internet Explorer or Firefox, I can relate. Some solutions did help improve Chrome a little, but there was only one thing that fixed the problem. Read More . If these tips don’t help, it might be time for you to consider switching browsers.

    Hardware acceleration (as far as I am aware) offloads display work from the CPU to the GPU thereby reducing the CPU load. I believe the reason that this isn't the default is due to the possibility of compatibility problems with one's specific display card. If there are no problems when selected, hardware acceleration should be easier on the CPU.

      Yeah, in theory that's how it's supposed to work, but according to the linked article there are times when enabling it could cause greater CPU usage. Best bet is to try both on and off and see if it helps. Thanks 12stringman.

        You're right about trying both Joel. On my system (old quad cpu) there doesn't seem to be a noticeable difference in response or speed with or without the hardware acceleration, much to my dismay. Good topic.

    Safari is faster then Crome.

      On Macs, you're right, Chrome isn't really the best choice. Safari is faster, but is still limited in a lot of ways, such as the lack of some popular extensions.

    I'm using "The Great Suspender" extension for a while, and I can say it actually helped a lot because I always have 15-20 or even more tabs open.

      Nice! That one looks great. Always wanted that kind of functionality in Chrome. :)

    Who says it's the "fastest"? In what way is it the "fastest"?

    Opera's still faster, IMHO and doesn't have to have little tweaks done to keep it from hogging cpu it doesn't in the first place, as any decent browser shouldn't be doing in the first place.

    Konqueror and Opera each use less than half of what my Pale Moon/Firefox/Seamonkey use in cpu cycles *and* RAM - average each Opera and Konqueror ~150MB.

    Pale Moon/Firefox/Seamonkey average each ~450MB RAM.

    Thing is, none of them feel any 'faster' in any way over the other. Well, no, that's feels like Opera does seem to startup about half a second faster than Konqueror, and both of those startup about a second or two faster than the other three. So, is that the "fast" that is being discussed in the Chrome article? A whole second or two at startup? If so, damn, I'm glad my life doesn't hinge around a whole two seconds waiting for something like it seems it does too many others.

    This is on my linux, with an AMD FX-6300 using all 6 cpu's in the background 24/7 cycling my seti@home units.

    What I would like to find is some way of preventing Chrome from hogging the bandwidth.

    There is a fairly new extension called "The Great Suspender" for Chrome that actually puts tabs to sleep when you're not using them. You get to choose how long to wait until it does that, and the tab instantly comes up again when you click on it. I have found this extension has reduced all the Chrome CPU usage to a bare minimum, and it has worked flawlessly. I don't even work for the company, either!

      Yes...I recently installed on my PC and added 4gigs of ram for a total of 8. The great suspender is also a big help. I love it. I don't work for the company either, but probably could have saved some $$ on ram if I had tried this first.

    cmon guys, it's 2016 now. what PCs pr laptops are you using? I have lots of projects and have to keep many tabs in different browsers and still have about 20-50% of free RAM (out of 8GB). every month on different resources I see such articles which only repeat the same: close tabs and remove extensions. WHY? I need them. upgrade your PC or at least use Tab Suspender for Chrome

      Totally agree with you on this one.

      Not every machine needs to be a beast. Try taking a gaming laptop on an airplane flight and see how long it lasts you! Sometimes a weak laptop is perfectly fine for the job. No use spending $1000 on a laptop if all you're going to do is browse the Web and write emails.

    Another thing that might help to reduce the heavy load is to install an ad blocker extension.

    If you normally have many tabs open chances are that some of those tabs are loading or running add content that contribute to increase the workload of your CPU.

    Finally if you listen to online music through a web page try to extract the direct link to that particular radio station or music stream and reload it with VLC or whatever music player you have set as your default one. This will help to reduce the massive CPU processing queue and to redistribute useful resources to other applications.
