MacBook Pro :: CPU Usage So High When Watching Video On Windows 7
May 2, 2012
I just installed windows 7 onto my mac with bootcamp. And I noticed that I have high CPU usage everytime when I watch a video from youtube or nba. My cpu usage would jump from 30% to 98% momentarily. What is the cause of this?
I've searched all over the internet but have yet to come across an answer. I love my Mac, but why is it that when I play a video in a web browser on my MacBook, (be it Flash, QuickTime, etc.) my CPU usage is anywhere from 60-80%, yet when I play the same video on a laptop running Windows, the CPU usage is always in the single digits?
I realize that video takes a toll on the CPU with integrated video cards, but it doesn't seem to have the same effect on Windows based laptops with integrated video cards. Is the CPU usage possibly just calculated differently, or is the Mac architecture somehow just really inefficient at this?
I just noticed that my CPU usage in windows 7 running in boot camp on my i5 iMac i newer lower than 30%... One core is almost at max, one is at a third of max, and the two last cores are idle. I've cleaned out in the "processes" tab in Task Manager, so that only the vital functions are running. Does it really take up so much juice to run Windows in boot camp?
My MBA (Ver A 1.6) just started getting the "sluggish" symptoms. Started noticing that my CPU gets stuck at 90~100% after about 30 min of use, since about a week ago. I keep restarting the computer and after about 30 min, my MBA becomes very sluggish and iStat shows both CPU bars all the way to about 100%.
When this happens, the activity monitor shows the kernel_task at 125~130. This is too high, right? If it is, what's causing this? I can't imagine that any of the programs that I regularly use will cause this.
I've noticed that my macbook pro has been using a lot of RAM. I haven't really witnessed a slowdown on my computer b/c of any sort of shortage of RAM but I was just curious if this was typical (since this is my first mac). I have 4 GB of RAM and I often find myself with around 1-1.5 GB of free + inactive RAM. I had a linux system with 3 GB RAM before and it used between 1-1.8 GB of RAM and it seems like this system is using around 2.5-3 GB (active + wired). However, various OS X laptops in the past have functioned really well in the past with 2 GB and even 1 GB of RAM right? Is OS X just putting more processes in my RAM to speed up my system because more RAM is available OR does snow leopard just have high memory consumption?
I believe there might be something wrong with my MacBook Pro-It's a late 2008 one, mid configuration. Intel C2D 2.4 Ghz, 2 graphics card, 2GB RAM, ... (Using SL)
I usually find myself using up most of the RAM, with 96MB of RAM left right now, and sometimes when using Photoshop, up to 15MB. My CPU usage is quite high, with Chrome using 17% + other Chrome processes.
I'm only opening up 13 active tabs with 12 pinned and disabled tabs; Is the CPU usage too high?
The HD crashed about 2 years ago, and since the replacement (TOSHIBA MK6034GSX 60GB) the CPU will go very hot 80+C and the fan going to 6200rpm if visiting some internet pages. Normally a problem if (when) the kids are playing free online games or visiting youtube or similar. Made a screenshot, notice CPU usage around 112%, smartfan showing 70C and 6200rpm. I have taken the mac physically apart and cleaned the cooling duct and applyed new thermal paste. Didn't help. It drives me crazy, I hate noisy computers.
I will be running MS Excel, preview, firefox, and activity monitor. All of a sudden my Activity monitor says that there is about % User of 50% and the fan will start running. I cannot find what program is making it run this high. I quit every program and it gets stuck on this until I restart the computer. I have done this about 3 times and it always comes back. None of the programs are registering high CPU usage. My last computer had an overheating problem where the fan was always on and that was part of the reason I switched to Macs - really hoping that issues doesn't follow me from Windows to Mac.
I bought one of these: [URL] and decided to do an experiment, now on standby (Laptop cover closed) it consumes 1.432 per night (8 hours). Laptop on standby, Cover Open but Display in Sleep mode for 8 hours costs 4.731 per day. So that means per month on standby at night, my Macbook costs 44.392. This can't be right? Because if it is, I might have to turn it off at night from now on.
I just bought my first mac (2010 13 inch base model) and i was looking in Activity Monitor when i noticed that my free system memory is around 15-20mb. Is this normal? The only things i have running is chrome, itunes, and steam. Would these programs eat up memory? if this is a stupid question please forgive me!!!!
My computer has been running incredibly slow lately. I think it has to do with the disk usage as every time it has to access the disk, it slows to a crawl. I've had a huge amount of beach balling, especially when loading a new App or a new page in Safari.
Here is a picture of the disk usage. Does this look normal? Does anyone know what the problem could be?
I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.
Just wondering if this is normal? Almost 30gb of VM in use? I'm encoding one of my DVDs and Handbrake is only using about 90mb of real memory while a bunch of background apps are using about 600-800mb of VM memory. Yesterday I encoded a DVD in like 20 minutes. I did a restart to refresh my memory but it's taken like over 2 hours of encoding and it's not done yet.
Whenever I start iChat on my new mini, it instantly spikes up the CPU usage and just sits there high. Activity Monitor says it's around 97%. I'm not doing anything in it; just starting the app gets it up there, and the only way to get it to go down again is to close the app. It doesn't seem to make a difference whether I'm online or off.
A few days ago I found that launchd was constantly using around 14% of my CPU (via iStat), which drastically lowered my battery life and caused my CPU to reach 75 degrees Celsius and higher. Initially I thought that SL just needed to do something, so I ignored it. But it has persisted for a few days now, so I decided to do something about it.
I checked the Console and nothing appeared to be repeating itself, so what I did was use MainMenu to perform a batch of system maintenance tasks, and then left my Mac on overnight to see what Console would report. Besides hourly instances of "kernel" running "iCalHelper" and "SubmitDiagInfo", there was nothing else.
However, launchd lowered its CPU usage to about 3%, but it is still constant and my CPU is still at a constant 40-50%. Activity Monitor says the following processes are (constantly) taking only 1-4% of the CPU: coreservicesd launchd mds WindowServer disnoted activitymonitord ...and others The CPU is reported as 35% User and 20% System. But I am not running anything besides Activity Monitor.
I've had my unibody Macbook since October. Recently I installed a few game apps including Sims 3. The problem is that when I try to play a game, it shows that my CPU usage is around the 100 range, the temperature is around 150 degrees, and the fan is around an average of 4000 rpm. It gets annoying cause you can hear the fan making a loud noise, I'm not sure if its my laptop or some other problem.
After standby mode my iMac 2011 with 10.7.3 seems to run corrupt with the kernel and activitymonitord tasks. CPU usage on one core runs to 100% only by scrolling fast in a window (finder, firefox, activity window). It happend without any system adjustment nor on any update or new software. Had the same issue months ago. Helped to went back to 10.7.2 and upraded again to 7.3 via combo update. System is after standby not usable, have to start system new as work around. Found same issue with other users on the web, but no solution.
Info: iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
I have white macbook c2duo 2GHz.After last iTunes update it still consumes about 60% of CPU whe running. If I say running i mean that it's not playing any music. Library Sharing is off. I was trying to find out something but i had no luck. Only I can say is that the same thing is occuring on my friend "Old" Macbook Pro (intel c2duo) but not on any iMac or Unibody Macbook i have seen.
Well I got rid of the quicksilvers since they died. Power supplys gave out and took the motherboards, So I sold what was left on EBAY.
My G4 Ethernet was sold to a co-worked and he is quite happy.
And I got this off ebay today:
Dual 1.8GHz PowerPC G5Procs 2GB RAM (2 x 1GB PC3200U DDR SDRAM) Pioneer DVD-RW DVR-117D Samsung HD160JJ/P 160GB SATA HDD (not apple labeled, not original to this system) (1) Power Cord pci106b,9 PCI Ethernet Controller
Well I didnt' read the fine print and BAZINGA! I noticed that it comes without a video card.
So For video editing, watching hulu and youtube and netflix What do you guys recommend.
I do have a PCI GEforce at home with 512 megs for PC and I was wondering if I could flash it and if so, does anyone know of a good walkthrough?
I bought one of the new-gen iMacs last month--my first Mac! My computer will often start making a low-droning noise, and it sounds like a fan. I have iStat, and usually during this time it will say that my Optical Drive and CPU Fan are both running at around 4000rpm. This happens when there is very little CPU usage too. It's happening right now, and I only have firefox running.
Currently, I have a 13" late 2011 MacBook Pro with 4gb of RAM. Right now, I only have 15mb of RAM free, and for some reason the rest is being used by an unknown process. I'll include a screenshot below
I see they are using the same CPU and GPU, so I'll assume they are going to stutter watching video like the other MBA's do. I'd be curious what someone more technically inclined has to say after looking at the specs and hardware, or if the flash memory hard drive might help with that.
I just got my air a few days ago, as a 2nd computer, a portable to go with my desktop. however I am finding that it is actually a bit too slow for my needs (i got the 1.6/80gb), even as a secondary computer.
I kinda wanted to use the air as my appletv device - to watch all the things I've downloaded on my desktop on my HDTV, which is in another room.
Loading up youtube and flash heavy sites seems to make the fan speed up to full blast. Watching divx movies also makes it spin up to max.
Some video files (notably RMVB real player files) play very jerkily and result in dropped frames, but usually the audio is alright.
All in all, quite disappointing as its a nice little machine otherwise. Just the dropped video frames and fan spinning up to max to watch files is kinda hard to live with. Anyone else finding this with their air?
