Does your rMBP/MBP run hot while playing flash

[Melons]

Here is a stream you can try today http://www.twitch.tv/cosmowright

It gives me 214% usage after fullscreen exit in Chrome. It takes you 1 minut to test it with activity monitor up and uploading a screenshot to imgur.

It wont help anything sadly. And why would i install Click2Flash when i want to watch flash? If people could just do what i ask for, which takes 1 minute, so i know if i should get my rmbp checked at.

Then why did you come here looking for suggestions? Most importantly, Click2Flash will stop all the ads. It's very easy to install and use, you simply click the flash content you want to see.

If you actually read my latest posts i ask for people to try out what i did, so i know if i got a faulty machine, because it ran weirdly hot when i ran w7 with bootcamp aswell. If you didnt see in the screenshots i run adblock, which is more then enough.

This is a base rMBP 2.3/8/256, running ML 10.8.2 and Chrome 24.0.1312.52:

About 180% CPU%. You can also see my temps in the menu bar, 75 degrees C.

Also that CPU% you're seeing isn't necessarily 1 core working at that percentage. Per CNET:

"% CPU

This is the percentage of the overall processing power in the system being used by the process, and is relative to one CPU core, so many times in multiprocessor systems you will see a process take up 150% of the CPU, which indicates in a 2-core system that 75% of the total CPU power is being used by that process. This will only happen for processes that are multi-processor aware, and others will maximize at 100% but the system will divide their work among the various processors.

When a process is programmed inefficiently, or has bugs in the code logic, the amount of CPU used can skyrocket and hog computing resources from other applications."

So if I'm reading this correctly, a process that shows 200% CPU utilization is in fact using ~50% of a quad-core's total processing power, and not overloading a single core.

In any event the heat the rMBP generates is new to me coming from the PC world. I have to keep reminding myself that 70-80 degrees C is within standard for the CPU, but there's no way I can watch a feed like this and keep this thing on my lap (I know, I know it's not a laptop it's a notebook).

It seems to be a common problem then, sadly. Yeah i know its not % of one core, since it doesnt make sense for something to use more then 100%, its divided between the cores. Too bad flash is so big these days, and html5 doesnt work with the protocol streams/etc use for the ads.

using the link you gave further up, my RMBP uses about 33% CPU when watching it but that goes down to 15% but never higher than 33%.

(I also have World of Warcraft running at the same time on another monitor, but flash (through safari) is running on the retina screen.).

And it was set to 1080p aswell? I wonder what is making such a huge difference in cpu usage.

Fans are idling at their normal 2000 rpm speed. Temps in the low 60s. I took 1000 samples in top for the affected process whilst running the clip in full screen mode. I get an average CPU usage of about 110%. It's basically what I expected from flash.

That is what I am getting more or less. On a 2.6 rMBP with 16Gb and 768 SSD. No excessive heat generated at all, the case stays at room-temp and can easily be held at my lap.

yep 1080p and like I said the laptop was running WoW and another monitor as well. Temp was around 75C but that was probably more WoW doing that.

Going to reinstall bootcamp with w7 tomorrow and see if the heat is the same as last time i tried it. Then im just going to get it checked at. Reaching 100c when watching 1 1080p stream isnt normal.

Tested this 1080p feed on a 2.6Ghz 15" rMBP in Chromium:

http://www.twitch.tv/erik33045

Background tab: 3-18%
Foreground thread:~45%
Fullscreen: ~100%

My fans stay calm after a few minutes, too boring to view for longer... Quicktime running a 1080p video sometimes gets up such CPU use (does it depend on codec?), are you sure this is a flash only problem?

In chrome i get

Background: 45-55%
Foreground: 89-98%
Fullscreen: 180-190%

So almost 2x on each one compared to you. Good to have some comparisons if i want to turn it in for repairs.

FS Twitch video (80C and 124.5%)

FS YouTube 1080p (75C and 55.4%)

FS YouTube 1080p (72C and 9.5%)

Cant say I'm surprised. Flash has always been a dog in OS X for as long as i can remember.

Plus a 32nm Quad Core CPU, a 40nm Performance GPU in a 0.95 inch thick Aluminium case means things will get toasty. Ditto for a 22nm CPU/28nm GPU in a 0.71 inch thick chassis.

No solution to this issue I guess.

New rMBP 2.6 i5 8GB ram 512 SSD. background twitch uses little cpu, not noticeable. Watching twitch in the small window 20%, fs 40-50%. Heats up in no time.
