Bootcamp CPU usage drops to 0%
Hey, so I have recently installed bootcamp windows 7 64 bit edition on my late 2012 mac mini with an intel i7 quad core 2.3 Ghz processor. I allocated 90 GB to the partition, and currently have about 50 GB free. I am having this problem where everything runs flawlessly, but at random intervals my computers cpu usage drops to 0% usage. My physical memory seems fine, as it runs at about about only 50-70%. At first I thought it was my CPU temperature causing this, as it was running at about 100 degress Celsius when putting a heavy load on my machine. However, after getting an application to control my fans, with my cpu at about 20-30 degrees lower I still have this issue. I am looking for any possible solutions, or at least causes of this problem. This type of issue does not happen on my mac OSX at all.
Thank you
Yes I understand that, however certain applciations freeze up when this happens. CPU typicalls runs at 20 % when browsing the web and higher when using some applications but randomly drops to 0, and these applications lock up. Is there any way to fix this?

Windows 7 Bootcamp CPU Usage issue
I just newly installed Windows 7 bootcamp on my MacBook Pro (2010). The installtion ran smoothly. But there seems to be a problem for me. The bootup time from being on to off or vice versa is 7 seconds flat.
And when I play games, my CPU usage would shoot up into the 80%-100%s making my screen freeze every 2 minutes, and typing anything onto a screen would take 2 seconds for my computer to compute.
Note: This was not the first time i install windows 7. The first time I did it, everything ran so smooth and fast. the bootup time would be at 2 seconds flat. no freezes when I play games or open anything up. How could I fix this?Hi,
I have an update so I thought I would share in case any other users are experiencing a similar problem.
I made an appointment with the Genius Bar at the Apple Store.
I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
I couldn't be happier. -
High CPU Usage / Dropped Packets - Switch Blade WS-CBS3120X-S
Hi all,
I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
Could you guys help us?. Any idea what is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).
Find attached the whole diagnosis outputs.
Thanks for your assistance guys.
Cheers,
Juan Pablo

When I am in e-mail, I sometimes get the spinning color wheel, which lock up everything. when it doesn't go away, I see on the activity monitor, that CPU usage is very high (99%), for a process calles " Safari web content'. When I click on the proccess and quite, the CPUusage goes way down. Problem is that I have to then log back in to e-mail. What can I do to eliminate this proble. thanks
How much FREE RAM do you have when this occurs. It's easy to tell, when it beach balls open Activity Monitor (Applications - Utilities - Activity Monitor) click the System Memory tab and note how much FREE RAM is listed. If it's 500MB or less it's time for a RAM upgrade.

Hello Apple family,
I'm having an issue with my Macbook that is rather surprising. Couple days ago I formatted it since it was almost 3 years since the last one and it was running a Lion install on top of a Snow Leopard install and it was in need of a good summer cleaning. I also had noticed that some of the more heavy tasks I was probably making on it were a bit slow, as in casual gaming and watching videos. So I started a fresh install, here is basically everything I installed:
I also installed via Homebrew: git and postgresql (and their dependecies).
Other little things I've installed or changes I've made:
Installed OSX FUSE
Installed Apple Command Line Tools
Installed Zend Framework
Disabled Dashboard
When I finally reached running a game, I got the exact same issue I was having before the format, and let me describe that. At first I start running the task and it behaves very well, all computer is fluid no matter what.
The problem occurs after a more or less 30 seconds: the cpu usage drops. I don't see any other process taking its place or fighting for the same resources, the only process noticed that rises a bit more is kernel_task (it jumps from 5-6% to 10-12%), but I guess its normal since we are talking about more intensive tasks for the kernel. Here is a some screenshots of the problem playing Heroes of Newerth (I'm using atMonitor and the Apple Activity Monitor).
Normal behavior, high CPU usage
CPU usage drops
CPU usage comes back to normal
I also had this same problem in other games (Swords and Soldiers e.g.) and also watching flash videos (ESPN.com).
Lets focus on this screenshot in particular. At the moment of the screen shot you can see the process is behaving normally: processor is at 77%, GPU is at 46% and FPS are at 27. But if you take a look at the panel on the right side, you can see the history before that:
CPU dropped to 10-15% and before that was on the values that were expected.
Same thing for GPU: at the moment is at 46%, but before that was at 5% and at the start was at 46% as expected.
FPS also oscillate from 27FPS when the system is running good, to 5FPS when the system is running "low". I guess its a consequence of the other 2 behaving abnormally.
Also worth notice, the RAM is never near full (as you can see from the screenshot above it stays around 50%); and the log (any of them) are not displaying any message when the system "drops".
Some procedures I already took:
Reset PRAM, SMC
Apple Hardware Test: It hang up 2 times, both at the same spot: logic board
Repaired disk and disk permissions (from the boot DVD)
Reseted Spotlight index (it was my first suspicion that was wrong after all)
I'm really hopeless here. I've googled thousands of stuff, but they are all the opposite of my issue - usually complaining about high CPU usage. Hope someone can point me into some direction. I hope the post has all the information needed, if you need anything else just ask.
Thank you all.
PS: Sorry about any english mistakes.A couple of things I think you should check:
1) Regarding using 200 users and having a queue of thousands of requests... When you say that you have 200 users, this means that you will have maximum 200 threads simultaneously on the client side, right?
2) What is the read timeout on the client side? That could explain the number of threads in use in weblogic. Threads might be left running, and if the client stops waiting for the response and initiates a new connection, it could lead to the scenario you are describing.
3) As you said that the web application starts consuming less CPU when the issue happens and at the same time the queue increases, it seems to me that you might have a contention on the webservices. Are you also monitoring the webservices? Do they run in a different server? Is it deployed on the same physical server but in different weblogic server, or it's deployed in the same weblogic server?
4) Did you run performance test in the webservices on their own to make sure that they scale?
5) In this situation, I would run a separate performance test against the webservices. Then I would stub the webservices and run a performance test in the web application. By stubbing the webservices, I'm able to create any kind of behaviour I want. E.g: Simulate slow response times, respond under a consistent response time, etc.
6) Is there a read timeout between the web application and the web service?
Regards,
Fabio Douek

I am running LabView 7.1 with DSC loaded. My project controls two reaction vessels through compact fieldpoint I/O modules. There are PID loops, data logging, trending and general value displays. The I/O is a mixture of analog and discrete. With trending enabled, my CPU usage jumps to 100%. This happens immediately, not slowly building over time. When this happens, the other portions of the program suffer, i.e. slower updates to PIDs and subsequently out-of-control loops, along with extremely slow updates to the screens. Disabling the trending results in the cpu usage dropping to around 3% and normal PID control and screen updates. The computer is plenty fast with enough RAM. Trending is vital to the technicians ability to manage the reaction. Has anyone seen this issue? I am using the read traces vi to populate the trends.
Sorry, I cannot test because of missing subVIs, but I would NOT place waits inside these FOR loops! They run for a limited number if iterations and do nothing special except some property nodes. Since your code is heavily sequentialized (sic ) all you do with these waits is prevent the program from doing anything useful.
What might help would be do defer panel updates during the sequence of FOR loops containing property nodes. (see e.g. http://forums.ni.com/ni/board/message?board.id=170&message.id=164135#M164135)
You have a lot of duplicate code that could be consolidated. Overall, the code is very hard to navigate because of the deep stacks of sequence structures.

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
ChrisHello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris -
Call Park service causing high CPU usage
Hi,
I've got a Lync 2013 pool with 4 servers running. Everything is working fine except I notice that when I enable the call park service, the CPU usage goes from hovering at around 4% to jumping all over the place (anything from 11% to 30%). I've
not seen this behaviour on any other Lync platform I have deployed.
All machines are virtuals, running 2 Sockets with 8 cores each. Each server has 25GB of RAM. Any perfmon report I run only confirm that the Call Park Service is using a lot of CPU resource (compared with other services)
Any help greatly appreciated.
Thanks
MikePlease check if the CPU usage drops down when you stop the call park service.
Please check the Call Park Configurations are correct by articles at

IPhoto cpu usage high, process isboxd
Hi All
Hoping you could shed some light on an issue i'm having with iPhoto. I've recently noticed that on launch it has been running a process called isboxd, and this is using a high amount of cpu power, and also pushes my core temp up to 80 degrees C. Once i quit iPhoto this process stops and cpu usage drops back to its normal 1%. I've tried quitting the process whilst iPhoto is running and it immediately restarts itself. I have also rebuilt my iPhoto library too and this hasn't sorted the issue either.
My iPhoto library is 56GB
I've only just started noticing this process happening, hopefully someone can shed some light onto what the process is doing, and if i can stop it.Then try to test in a different user account. You might want to enable the guest account for testing. If you are seeing the same proble in a different account, that would show that your iPhoto preferences may be corrupted.
Delete the iPhoto preference file: com.apple.iPhoto.plist from your ~/Library/Preferences folder.
In Lion and Mt. Lion also the cached file in
~/Library/Containers/com.apple.iPhoto/Data/Library/Caches/com.apple.iPhoto
The library is hidden in Mt. Lion: To remove the files:
Click somewhere on the empty Desktop to bring the Finder forward.
Select "Go" in the Finder's main menu bar and hold down the alt/option ⥠key, until you see the "Library" in the drop-down menu. Double click it to open a Finder window, so you can browse the files inside.
Scroll down to the "Preferences" folder and open it.
Remove com.apple.iPhoto.plist
Note: this will reset all iPhoto preference settings to the default values, you may want to take a note of them, before you do that. -
Dock constantly at about 10% CPU usage?
Hi everybody,
I'm new to the mac, so please excuse me if this is a stupid question!
When I take a look at the activity monitor, the Dock is always at 9.5-10% CPU usage, even when it's hidden. Is this normal? I can't imagine it's meant to be this way, 10% is quite a lot for a simple menu, in my opinion...
Thank you for your help!Okay, I have found the cause of the problem, and I don't get it.
The longer my chrome browser has been open, the higher is the CPU usage of the dock. After a couple of hours it'll be at 2-3%, after a day or two it'll be around 10%. When I just quit chrome the Dock's CPU usage drops to 0%, whenI start it again (with all the same tabs open saved and reopened), the Dock's CPU usage will remain at 0 for a while and then start creeping upwards again.

NMIndexStoreSvr.exe causes high CPU usage
Within 2 - 24 hours after I restart my computer I'll notice that the CPU fan is very loud. When I open Windows Task Manager the CPU is at 95-100% usage. When I look at processes I see that the file "NMIndexStoreSvr.exe" is the biggest culprit. When I end that process, my CPU usage drops to 5% almost immediately.
Ending this process does not seem to affect Itunes. Has anyone else run across this. Is there a fix or a way to keep that file from running when I start up Windows?
Any help will be greatly appreciated.Hi Adrian1988,

High CPU usage: Animation with background
I experience a high CPU usage when animating a shape over a background. If I disable the background or the animation, the CPU usage drops to almost zero. It seems like the combination of background shapes and an animated shape is very costly.
Is there a way to improve this performance? Can I indicate that the animated shape is always on top? Adding the smooth and cache tags did not improve the performance.
Thanks in advance.

High CPU usage HP2000 Notebook PC
About 3 weeks ago I purchased your HP2000 Notebook PC, model #E0M17UA#ABA. Almost immediately I started getting "High CPU Usage" messages and everything is painfully slow. It does not matter whether I am reading the news, watching a videa or sorting my email, I get the high CPU message. The system is 10 times slower that the HP that I bought last year for my husband and I find if I don't have alot of time to perform a task I just use his. Over the years we have used HP Products almost exclusively because of their reliability and when I had to replace my last laptop there were several in the same price range but it was the HP name that made the decision. Is this fixable? I travel frequently for work and I need a reliable system that I can actually use.
It is very hard to find the true specifications on this system. The actual processor speed is not listed in most of the literature like this:
spec sheet
With a bit more digging it turns out it is a 1.3 ghz processor with 1 meg of L2 cache and dual cores. Basically, it is a very weak computer processor that is not much more powerful than many tablet and cell phone processors these days. It was made to blow out the door vey inexpensively at Wal-Mart. I just had one of these in my hands yesterday and the owner was having the same problems. Increasing the RAM to 8 gigs helped a bit but the thing that made is useable was to remove all the HP add-on packages, remove the McAfee antivirus and install Avast antivirus and lean up the startup sequence so that not so many processes are constantly running in the background. CPU usage dropped from a constant 100% to the 20s and 30s percent during web browsing and made the unit useable at least. It is never going to be a powerhouse, but if you configure it to run lean and mean it is workable for web browsing, office work and even watching DVDs and online video.

USB Devices Not Detected and High CPU Usage
Hello, I'm using arch on a Dell 1720 laptop.
I have some weird issues involving detection of USB devices.
When the laptop is on battery and I plug in a USB mouse the power flickers on and flickers off again; nothing in the logs/dmesg.
If I then connect the AC adapter the reconnect the mouse, the same happens, except the CPU usage hits 87%+ on one core.
Running
sudo rmmod ehci_hcd
solves the problem; the CPU usage drops and the mouse gets detected.
Subsequent attempts to hotplug USB devices does nothing, no high CPU and no Power.
Rebooting the computer is the only way to use USB devices at the moment.
usb-autosuspend is disabled in laptop-mode.
uname -a:
Linux MatSalleh 2.6.39-ck #1 SMP PREEMPT Sun Jun 5 18:30:30 EDT 2011 x86_64 Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz GenuineIntel GNU/Linux
The same happens with the stock kernel too
My kernel line in grub:
kernel /vmlinuz26-ck root=/dev/sda3 elevator=bfq ro resume=/dev/sda2
Any ideas?
Thanks,

I highly doubt it's that, it was working fine on ubuntu just days before...

This one helps me to solve this problem
My USB devices don't even get detected, so that script won't work.
Last night I hibernated my computer after not using any USB devices, on resume, my CPU usage was 100%, removing the ehci_hcd module fixed it.
Any more ideas?
I'm tempted to build a vanilla kernel...
