This is an outdated link to something discussed on Tom's Hardware that went a little into Flash performance across a few (now dated) browsers so the numbers are just a historic reference now and not to be considered updated/current data. So historically speaking, Chrome appears, at least back then, that Flash CPU usage is on par with some of the lowest to include Safari and Firefox/IE8 have had higher instances of CPU usage.

During that time, the one thing I can pretty much state is that Firefox appears to have the highest CPU usage among the rest.

I would like to point out look at the FPS. FF had the highest FPS followed close by IE. Both of which blow the rest out of the water by a healthy margin.
 
Browser market share is highly debated. It's hard to measure, and depending on the sources will vary wildly. Macrumors probably has very high Safari usage, while other sites don't even see it as a blip on the radar. Some sources (NetMarketShare) peg IE at 50%+ still, while others ([ur=http://gs.statcounter.com/]StatCounter[/url]) say it dropped to less than that of Chrome recently (32.xx % to 31.xx%). This PC World article talks about this :

Which is right ? Which is wrong ? Why are we discussing this and what is the relation to this thread's topic ?

Higher FPS results in higher CPU usage. Who knew... ;)
 
In my feeble mind I don't know why there's a variance between Flash performance between different browsers, in fact the comment regarding the differing FPS does present a valid point, and KnightWRX's comment is spot on regarding the relationship between higher frame rates and increases in CPU usage.

Are there different target settings between each plugin/extension for each browser? For example does FF aim for a particular FPS (or Flash performance level) which is set higher by default than Safari or Chrome? I don't mind higher CPU usage if it provides better results.
 
Having Google Chrome open gobbles up battery power because of the way it enables GPU acceleration, causing the dedicated graphics to fire up.

Ironically, this update to Chrome is probably a good one for all users with a MacBook Pro because it will likely increase battery life.

You know you could force Chrome to use the integrated graphics through gfxcardstatus.

Issue was fixed in Chrome 16 :

Issue 88788: Chrome always triggers discrete gpu

So just run the latest Chrome (version 20) and Chrome will be using the integrated graphics already. Basically, people whining about battery usage and discrete GPU are just repeating stuff they heard like a year ago, not actually running Chrome and seeing the behavior. ;)
 
This is ridiculous i had to force quit Chrome now when i open it i can't even click anything without the rainbow ball popping up. Im not even using a new Macbook Air/Pro i have a refurbished Early 2011 Macbook pro

Reformat the disk and reinstall the OS and let us know if there's still a problem.

(Don't know if it will help, but one often hears that advice for Windows users.... ;) )
 
or a typical Mac solution is to repair disk permissions.

I've tried repair disk and re-installed mac os x and Google chrome still won't work. I only want to leave a clean install as a last resort.

----------

Actually its working ok for now, i just had to be a little patient. I'll see how it goes...
 
Exactly, but doing so seems to be the "typical" Mac fix-all solution to all of life's problems. :D
 
Yep, it is very clear. Problem is in OSX. Applications can crash as often as they want. However when application crashes whole OS that clearly indicates problem with OS. It is simply not acceptable that application is able to crash OS.


Please give me an example of poorly coded application, which crashes Windows. Not Windows 98, but Windows 7.

Lotus Notes.

----------

I read it as "Google issued a statement saying 'Hahaha all you Apple fanboys got PUNK'D! Enjoy your new CrashBook Airs!' "

You act as if Chrome is the only option.

----------

Exactly, but doing so seems to be the "typical" Mac fix-all solution to all of life's problems. :D

Unlike reinstalling the entire OS for Windows?

Which doesn't quite do what people think it does. Repairing disk permissions in Unix hardly fixes anything other than "Permission Denied" when opening files/launching applications.

Access denied IS a big thing.

Sure, but it's pretty binary in the nature of problems it causes (either you have access or you don't). "Beachballs!" aren't Access Denied nor are most problems faced by the people getting told to "repair permissions".

Lotus Notes.

Fixed in January 2010 - why even mention it?

I'm not finding anything online about Lotus Notes crashing the NT system, just that Lotus Notes 8.5 seemed to be rather crash happy on Windows 7. So why even mention it when it isn't even what is being discussed here (misbehaving application bringing down the entire system) ?
 
Problem for older Macs?

I'm running a 15" MacBook Pro that's coming up to two years old, (OSX 10.6.8) and I've been having what sounds like the same problem. About five times in the last few days, I've been using Chrome when my system completely locks up. I can move the cursor but not interact with anything and have to do a hard shutdown with the power button. I know this Chrome issue is a problem that's chiefly been affecting newer Macs but could it also be causing the problems wth my system?

In some ways it would be reasuring if it was as I've been starting to get worried that the freezes are indicative of a major problem with my whole computer. Really appreciate it if anyone could shed some light on this.
 
Chrome Canary crashed my MBPr

Just had my first kernel panic while running Chrome Canary. I guess that's what I get for running the nightly build. I also noticed that my battery life while running Canary is much worse than when running only Safari. Weird.
 
Does anyone know if Apple will be releasing a software fix for this kernel bug or if we have to wait until Mountain Lion?

I think they have to acknowledge it's a bug first. (Although I read that Apple released a fix for the MacBook Pro 2012 that had a possibly similar issue with the GPU driver and the Intel Graphics 4000)

My impression is that most users are attributing crashes and freezes to Chrome and hence waiting for Google to fix it - the fact that Google are saying they are working on a fix only would endorse the view that it is an isolated problem.

Just Chrome really?!

Personally I am with you - I have just been adding up my kernel panics since I got my MacBook Air - 19 panics in 17 days. I cannot be definite but I reckon first 3 or 4 were with Chrome - I uninstalled it after that.

One later one was with Chrome Canary - after I heard Chrome Canary might be a fix.

One was while running Lightroom 4 (no broswers running) and my latest was with Safari running (no Firefox running at the time).

One Solution: Create and use and new user profile

At the moment I am testing a possible solution given to me at the Genius Bar which was to create a whole new profile and run with that. To date I have only had one Kernel Panic under the new profile. I am waiting to see how stable this solution is. If it happens again the solution is a full clean install - although I will book my Air in for a full scan at the Genius Bar first.

Sadly it is not like the old days when I would say the great things about Macs are that they just work out of the box. :eek:

On the plus side the support from the Genius Bar has been good. :)

Fingers crossed. (Must say it is a little odd that now I am using a Mac nervously hoping I don't get a kernel panic...would have been a little more confident in the past).

Maybe the issue will be confirmed, recognised and solved with Mountain Lion. (I might wait a few days before switching to it though - just to see if any bugs come up during the first release. :))

UPDATE: Have had two Kernel Panics since posting this - both using the new profile and with Safari. Have booked time at the Genius Bar and requested a full hardware scan.


UPDATE 2: Took my MacBook Air into the Genius Bar - the Apple Genius guy looked at the Console and the logs for about 5 minutes and said - let's replace this...and so now I have a new MacBook Air. Fingers crossed. :)
The logs indicated an issue with the SMC - after he saw this he made the call.

I asked about issues with the GPU (I had read MBP had this problem and he said he had only encountered this once with a 2010 MBP).

I know I was having HUGE frustrations with my new MacBook Pro, 3 crashes on the first day out of the box. I got rid of Chrome and the thing has been running like a champ ever since. I may Chrome again when the new Mountain Lion OS is on my Pro.
 
While Google has disabled some of Chrome's GPU acceleration on an emergency basis as it seeks to deploy a permanent solution, the company has also filed a bug report with Apple as such issues should not be able to cause an entire system to freeze or crash.
Very robust apple OS.
 
I know I'm kind of late to the party, but it's not just newer Mac notebooks. I'm having the same issues on a 4 year old iMac. I stopped using Chrome and the freezing stopped.
 
Ever since I installed chrome on my MBA, my battery life has increased by exactly 15%. The reason I know this, is the work I do involves timed sessions. I continue to be amazed at the excellent work Google does. Although I do realize it's fashionable for Apple users to hate & bash on Google, I would be lying if I didn't report how well it works on all my Macs & ThinkPads.

In addition I'm particularly happy & impressed with the constant stream of bug free upgrades they push out. Self installing as most of you know, it happens automatically in the background. So smooth & fast, you don't even notice it.

As much as I'd like to promote Safari, the truth of my experience reveals nothing is as superb as Chrome. The huge number of free, useful extensions have overshadowed my past favorite, Firefox.

Chrome has become such a pleasure to use, has sped up my workflow so dramatically, it's a must have for me.
