High CPU usage caused by graphics cards visibility problem

I bought a laptop Lenovo G505s with dual graphic AMD Radeon 7640G + 8500M. The graphics cards configuration is totally normal on my Windows 8
, but only the 7640G is visible on Ubuntu:

When I start video application like GoogleTalk, Skype or VLC, the processor eat up to 250% of CPU.

I've done a lot of research and followed many tutorial. I've already tried all the 3 drivers (fglrx, fglrx-update, xserver-xorg-video-ati) and the driver from AMD site. I've followed this Ubuntu Wiki, both via command line and manual install, but no success. Please, anybody help. Thanks a lot.

High CPU usage caused by system interrupts [Satellite L50-B-1DG]

Just installed 64bit versions of windows 8.1 & windows 7 on a brand new Satellite L50-B-1DG, and literally without any programs installed, the CPU usage does not fall below 45%.
The windows 8.1 task manager suggests this is caused by system interrupts, so I tried the following without any luck:
1. installed latest version of all drivers
2. disabled all devices one by one to trace the root of the interrupts
3. used latencymon to trace the driver behind the DPCs, and while the program suggests that it is caused by aspi, again I cannot trace which device causes the interrupts (I have already disabled them all)
4. re-installed windows 8.1/7 multiple times, no difference
So, is this normal? Is this caused by faulty hardware? People with same models notice anything similar?
Cheers

High CPU usage when graphics card is put at work

I have a 13inch Air with 2GB RAM and 256GB with Windows 7 Ultimate 64bit. All possible updates have been installed.
I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
Has anyone experienced the same or know what could be causing the beavior?
Many thanks

Maybe my initial post was not clear so let me add some clarifications.
I have the problem with Aero disabled
I have the problem on the Apple site which does not have any flash content.
I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
It would be great if someone you also do the test to check the cpu load:
- when playing a 720 mkv
- when dragging a window across the screen
Just open task manager and see if the CPU spikes.
Many thanks!

XML select query causing very high CPU usage.

Hi All,
In our Oracle 10.2.0.4 Two node RAC we are facing very high CPU usage....and all of the top CPU consuming processes are executing this below sql...also these statements are waiting for some gc wiat events as shown below.

Also not able to generate execution plan for this sql using explain plan- getting error(ORA-00932: inconsistent datatypes: expected - got -)
Please help me in this issue...
How can i generate execution plan?
Does this type of XML based query will cause high GC wiat events and buffer busy wait events?
How can i tune this query?
How can i find that this is the only query causing High CPU usage?

Mixer window can cause high CPU usage, crashes

This is probably one of the weirdest bugs I've seen for a while. Here are the steps that I reproduce it for me, maybe someone will want to try this out and see if they get the same.
1) Open an Empty Project template.
2) Create 16 instrument tracks when it gives you the dialog. (even 1 will be enough, but the effect is clearer the more tracks you create)
3) Open the mixer. Either in a window or in the pane.
4) Now create a "multi-timbral" instrument track with the plus button (use the checkbox there).
5) Select the 16th track, and now select one of the arrange tracks of the multi-timbral instrument.
6) Open up Activity Monitor from your Utilities folder in Finder and see how much Logic is taking up CPU. It should be significantly higher than the idle state. On my MBP it'll be around 80%.
This is not a problem in itself, because when reproducing it like this the high CPU usage goes away when you select another track and won't return if you select the multi-timbral instrument again.
However, I have sessions where this will continue happening with a multi-timbral instrument all the time. Not only that, I've had Logic crash when this starts happening. And this whole thing will slow down the UI considerably when it's active.
The workaround that seems to work for me is simply not keeping the mixer window/pane open.

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue
http://thoughtsofmarcus.blogspot.co.uk/2013/06/leaving-password-blank-in-biztalk-2013.html
Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

Wake-On-Lan (WOL) after sleep causes high CPU usage

Hi,
I noticed a problem with constant high CPU usage on one of my cores.
As much as 60% was used.
The problem occures after I put the system to "sleep" (S3 state) and perform a WOL with a "magic packet".
I discovered that ACPI.sys+0x1af44 thread was responsible (using sysinternals ProcessExplorer) under the System process.
If i perform WOL while the machine was shut down everything works perfectly.
My NIC is "Realtek PCIe GBE Family Controller" and I'm using the latest drivers.
I discovered that if I disabled the option in Power Management for the device: "Allow this device to wake the computer", the CPU usage immediately went to normal (without restarting). But enabling it back the high CPU usage resumes. Performing
another sleep and awaking the system with power button "resets" the CPU usage issue for "good". Until i WOL from sleep again ofcourse..
I contacted the motherboard manufacturer of the problem but so far no real answer.
I'm saddened because I need the WOL feature.
I'm hoping somebody who has more insight in the behaviour of ACPI on W7 can answer my questions.

What Causes High CPU Usage Even When PC is Idle

Screen Sharing freezing and high CPU usage

Hello all,
I use screen sharing to remote my mac mini as a media server connected to ma HD TV to play movies, music and surf.
Since I upgrade to mavericks on my macs (Macbook Pro Retina and my Mac Mini) I have some troubles with the screen sharing feature.
No problems with the login step, the connexion is fast, all permissions are OK (I saw there were a bug with some RDP release) but sometimes, when I use fullscreen software as VLC, Firefox, etc (not the native apple full screen feature, I just clic on the + at the top of the window), my sreen sharing freeze and I can't do or move anything on the remoted mac mini. I'm unable to close (or reduce) the screen sharing app too, it's totaly busy (But I can see the movie or the website on the 2 computer, there is no deconnection)... I have to kill the process through the monitoring activity.
During the freezing time, I try to use vnc light from my Iphone and I have no problem, I can move the mouse, reduce le VLC windows... As soon I reduce the VLC windows, the screen sharing works again. I also use the logitech TouchMouse to remote the mouse, everything work fine.
Here are a screen shot of the monitoring activity of the Mac running the screen sharing app, we can see that there is a very high CPU usage when I use VLC in fullscreen on my mac mini. The first is in normal mode. The second is in freeze mode. Screen Sharing is named "Partage d'écran".
Can someone help me to fix that, everything works fine with Mountain Lion.

I have a Macbook Pro 13.5" 2.8 GHz 4 core (2 real, 2 hyperthreaded) i7 machine running with 1920X1200 display, 3 virtual screens and VMWare adding a few virtual screens (full sized). I have another Macbook Pro 15" with 2.6 GHz Haswell 8 core (4 real, 4 hyperthreaded). I see the problem using Screen Sharing on the 15 inch (Retina screen) mode simulating 1920 X 1200 pixels using Screen Sharing to the 13.5" Macbook Pro.
When I get the ScreenSharing problem, I have identified it as related to the VMWare screen on the 13.5" Macbook Pro being shown through Screen Sharing on the Retina Screen. Before you conclude it is a VMWare problem, the computations are only on the Screen Sharing client side, not on the server side running VMWare. The mouse gets unusable through Screen Sharing. If I physically move the mouse on the 13.5" Macbook, no problem. If I switch virtual screens, the Screen Sharing goes to normal processing.
I see an appearance of a compute-bound thread on the Screen Sharing client. It takes 100% CPU on one thread, the machine as a whole is 12.5% busy (the performance monitor considers all 8 threads as equal when in fact, they are not).
A few more pieces of information. The VMWare client ends up having a lot of overlapping windows with a lot of changing graphics. My mouse runs into problems especially when it is overlaying a changing plot (Perfmon running in Windows 7, or updating email client). It does turn out that VMWare has a "native" VNC server built-in and I tried to connect to the virtual screen using the Screen Sharing Client on the machine with computing problem and voila!, no problem. I end up having a Screen Sharing Client running native running screen (supposed to be VNC, but I have not verified that) sharing protocol on a virtual screen that is NOT the VMWare virtual screen and a separate session using actual VNC protocol using the VMWare VNC server. It works perfectly fine.
If I may hazard a guess, I think I know what the bug is, or at least, what is the nature of the problem that I have. The rest of you may have a different bug. When I have difficulty, it is because I am on a window that suppresses the dock, both in remote virtual screen and on the local machine showing the screen. Two docks are suppressed, one remote, one local. Throw in overlapping windows with changing graphics in the overlapped windows and toss in a mouse on top of that. I think that the Screen Sharing is trying to refresh overlapping windows with mouse and going through the suppressed dock calculations and never converging on what the picture should be. The mouse ends up being the visible cue that shows the time frame for iterating the windows - flickers with a timeframe of greater than a second. That is far greater than the screen update time. It is totally compute bound with all the overlapping stuff that it is deconflicting. At least, that is what I think is going on.
Meanwhile, the VMWare VNC server appears to send out a single graphics context and causes the Screen Sharing client to converge to a picture. Note, the mouse appearance is very different when attaching to the VMWare VNC Server rather than the ScreenSharing native server. I see two mouse renderings, the virtual machine remote and a mouse rendering from my Screen Sharing client side. They are mostly in sync in position unless I move the mouse very quickly. If I use Screen Sharing client and server instead, I usually see only one mouse, the client side's mouse rendering.
I have a solution for my problem. It is similar to using a different VNC server/client pairing. I will use a VNC server for the systems giving me trouble that is not Screen Sharing Server exercising a probable bug in the Client (though, it could be a problem in the design of Screen Sharing itself).

High CPU Usage in Word 2013

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.
Chris

Hello 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

High CPU usage warning, how to fix??

Hey all -- First off, my laptop is brand new, and it is a Satellite C875D - S7120, using Windows 8. So far so good, everything seems to be fine EXCEPT...I am an artist and I have a couple of 3D programs installed. But every time I try to use them I get a "High CPU usage" error, like the art program is taxing the computer too much. I'm not a gamer... it seems to me that simple 3D imagery wouldn't cause this. But how do I fix it? I'm not that computer savvy...I've heard about registry problems but wouldn't have a blind clue how to get in there and fix anything... PLEASE ADVISE! -- Thanks in advance, Krystal

Ahh, Jerry, you are a friend in (my) need...will pounce on this ASAP! Twiddling around with this new device of mine is a challenge but also a learning experience. Probably the most important thing right now is NOT getting it 3D-ready but instead, teaching myself how to manage the innards...
Moki, someone on deviantART who is very skilled w/ Blender has said that they don't like the latest version because it is quite different from earlier versions. I haven't done anything with it in yonks, so once I get into it again, that shouldn't bother me. But it's true, "improvements" always seem to just weigh a program (any program) down instead of making it easier to use. That was why I have preferred older versions of some things instead of what's new out there, as the older ones are slimmer and not such resource hogs...
Disabling RayTracing...hmm! I shall definitely do that...plus try all the many other tips! *bookmarks page* I could even try that on this old XP, since I have Blender installed here also.
So if Toshiba is strong enough to handle graphics projects way beyond my modest little ventures (I doubt I'll be making movies anytime soon!), I ought to be able to get this puppy set up for it without too much trouble....let us hope....

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

Mediaserver high cpu usage on Pre

I've finally narrowed my performance issues on the Pre 3 primarily to a high cpu load caused by the process "mediaserver". If I manually kill this process the phone speeds up significantly, and it doesn't seem to affect anything if the browser is closed. I suspect one of the spawners of this task is Flash; streaming video also likely triggers it. Closing all cards after the high load begins doesn't help; the process must be terminated manually. I hope that an update will arrive for the Pre 3 that fixes the performance (and high memory usage) along with complete Skype / bluetooth phone integration and other bluetooth fixes. At this point I'm torn between the great Pre 3 hardware and just switching to a Pre 2.

Has this been something that just recently started happening, or have you had this issue for a while? Have you installed any new programs recently?
You may want to download Glary Utilities, which is a free software(they will ask you if you want to go Pro, just say no, the free version works very well). There is a module for startup manager. You can go in and disable stuff that starts with the computer. I would advise unchecking adobe, java, quicktime, printers, etc. Anything that doesn't REALLY need to start with the computer. The nice thing with Glary is that you can restart the computer, and if you find that you need one of the programs to start with windows, you can go back in and enable it again.
The Celeron 925 processor in your computer is a decent entry level processor, but if there are too many programs running in the background, it can bog down quick. I would also recommend downloading and running Malwarebytes Anti-malware, to be sure that there is nothing malicous running in the background.

/usr/lib/jvm/java-7-openjdk/jre/bin/java -Xbootclasspath/a:/usr/share/icedtea-web/netx.jar:/usr/share/icedtea-web/plugin.jar:/usr/share/java/js.jar: -classpath /usr/lib/jvm/java-7-openjdk/jre/lib/rt.jar sun.applet.PluginMain /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-to-appletviewer /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-appletviewer-to-plugin /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-debug-to-appletviewer
I have the following java packages installed on my system:
local/icedtea-web-java7 1.5-1
local/jdk7-openjdk 7.u51_2.4.6-1
local/jre7-openjdk 7.u51_2.4.6-1
local/jre7-openjdk-headless 7.u51_2.4.6-1
I also get the following message in my system log when starting to stream:
Apr 11 12:26:18 saturn logger[7872]: IcedTea-Web java error manual log:
Apr 11 12:26:18 saturn logger[7873]: Application title was not found in manifest. Check with application vendor
Apr 11 12:26:37 saturn logger[7883]: IcedTea-Web java error - for more info see itweb-settings debug options or console. See http://icedtea.classpath.org/wiki/IcedTea-Web#Filing_bugs for help.
Anybody having this issue or clue on what to do? I am wondering if recent changes to openssl (heartbleed) might have java change ramifications? Should I submit bug to Icedtea?
FYI - My system:
Processor : 4x AMD A8-3870 APU with Radeon(tm) HD Graphics
Memory : 7646MB (2518MB used)
Operating System : Arch Linux 3.14.0-4
OpenGL Renderer : Gallium 0.4 on AMD SUMO
X11 Vendor : The X.Org Foundation

...further research and learning.
Here is a good tutorial on Java. Evidently, what I called "jobs" is referred to as processes and threads in this tutorial. The tutorial states that multithreaded execution is an essential feature of the Java platform which explains the avalanche of threads I observe. However, I am still stumped at what causes the avalanche of threads and excessive CPU consumption for such a mediocre task. Also the system log says that IcedTea has an error stating "Application title was not found in manifest. Check with application vendor". I interpret this to mean that IcedTea does not recognized some application. What application? .....the applet?

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Hello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.
