Why is my CPU usage in quicktime on 10.5 so high compared to XP?
I have a 2.0 Ghz mac mini with the GMA950 and a windows XP machine at work with a 2.1 Ghz core 2 duo and the GMA950 also. When I play one quicktime HD movie I have on the mac it uses about 150-175% out of 200% of the cpu but when I play the same file on the XP machine it uses about 30% out of 200% Why is that since they both have the same GPU and almost the same CPU?

The answer is simple I'll tell you.
Because QuickTime for Windows doesn't need to consider much as it in Mac one, if you spent time on Windows you probably found it will crash other programs and even freeze the whole PC, because software in Windows doesn't care each other, they don't know each other, fine! But they don't CARE each other EITHER! That is what Windows all about! So the program can use less CPU power.
But QuickTime for Mac is quite different, QuickTime in Mac considers integrated operation. It will coordinate with other programs in Mac OS perfectly, so you can watch QuickTime movie in four space while click F8 simultaneous, something like that, you got what I mean? But you can NOT do that in any Windows system, not Windows 95/98/XP, even Windows Vista can NOT do that. Guess what? Only a Mac CAN do that.
So, who cares about the usage % of CPU? That's what a CPU born to be so.
Why bothered? You should be happy you have a Mac, not Windows, Windows will never learn its lesson. All you just forgot, Windows is just a complex fat boy copying Mac OS all the time!

Why is the CPU usage different ? I used LOAD_BALANCE option.
I used a oracle 11.2.0.2 in RAC 2 nodes.
And I used LOAD_BALANCE option in the WAS pool configuration
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.10.118)(PORT=1522))(*LOAD_BALANCE=YES*)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=NOFFICE)))
But the CPU usage is different between two system. Usually it is 6:4, Sometimes it is 7:3.
Is it normal?
I want to a balance in CPU Usage (5:5).
If it is the better solution about a Load balance. i want to know it.You are partially correct which is another way of saying you are incorrect too.
There are two types of load balancing ... server side and client side. There are also questions with respect to how the client is connecting, we don't know, whether the session load is identical, etc. which the OP has not stated.
The only thing I can absolutely say at this point is that what the OP has seen is normal and I can't see any reason why, unless the skew is very large and very permanent, anyone should care.
To the OP: Let's step back from the "what I want" statement and go to the basis of your inquiry: "Why do you care? Please provide a business reason and cite specific performance metrics, from your system, showing the problem you are trying to address. Then perhaps we can help you. -
Why is Flash CPU usage so high on my PC?
To other psoters here - Please do not hijack my thread for any other performance issues with Flash other than high CPU usage.
This thread is (hopefully) dedicated to why the CPU usage on my desktop PC jumps when I go to a page with flash 'content'. Thank you!
I am hoping that there is an answer for why my computer is using a very high amount of CPU percentage when I am viewing flash content?
I am running Windows Vista Home Premium Service Pack 2 on a Gateway GT5432 desktop computer.
I have Shockwave Flash version 11.7.700.169 installed.
I am using Firefox version 20.0.1 (but I have seen same problem of high CPU with Google chrome).
Here is one page that is causing the high CPU usage.
- http://logansroadhouse.com/Default.aspx
That page appears to have lots of Flash content.
If I open that logans roadhouse page, my CPU usage goes from an average of 12%, to 80%!
The process I see jump are:
- Firefox's "plugin-container.exe" goes from 0% to about 50%
- Firefox browser "firefox.exe" goes from around 8% to 14%
- Adobe's plugin "FlashPlayerPlugin_11_7_700_169.exe" goes from 0% to 16%
- TOTAL CPU change from 8% to 80% after opening up just this one page !
When I close the page, the CPU usage goes down again. Open again - CPU goes high again.
Also if I go to the firefox addons page and DISABLE the SHOCKWAVE FLASH plugin, then go to that Logans Roadhouse page, very little of the content I saw with Flash enabled is visible - which I take to mean it is a page consisting of lots of Flash 'content'. Also the CPU usage remains low (8%) if I go to that page - after disabling the Shockwave Flash plugin.
I have seen the CPU also go high on youtube.com pages also - CPU jumps just as I said above - if Flash is enabled. CPU then drops after disabling Flash plugin.
I was hoping you had a fix for my problem? My PC becomes almost unusable with the CPU so high. It sure looks like it is the Flash plugin driving the CPU so high.I am also facing the same problem from last 2-3 weeks since i upgraded my flash player to latest one.
All softwares and drivers are upto-date.
I play wartune MMO flash browser based game (also applicable to youtube videos) which is now using above 80% of CPU. Before upgrading, CPU usage was normal around 5-15% depending upon the events, but not more than 20% even if i open 3-4 accounts of wartune in different windows at the same time. It happens in all browsers (IE10, Mozila22.00, Opera12.15, Chrome27.0.1453.116 m).
I tried all solutions like disabling hardware acceleration, flash cache size to unlimited, clearing all flash cache etc but the same problem.
Please fix this problem as soon as possible.

I notice when I burn a project on iDVD the activity monitor shows the cpu usage btw 140 and 160% when encoding the video and like 30% when encoding the audio. I'm guessing if it showed 200% it would be utilizing all available processor power. Note my macbook has 2GB ram. This bothers me because the other day I encoded a video file that was 800MB that was 100 minutes and it took a little bit more than 4hrs to encode that. I didn't have anything else running? What gives?
It also really depends on what software you are using for the encoding. I've played with several the last couple of days and found out some interesting stuff. I used Toast 7.1 to encode a DVD into DivX for playback on a hardware DivX player. A one hour episode took 2 hours to encode using Toast (on my new MacPro). One processor was pegged, and the other three were basically idling. Today I used HandBrake to do the same exact task. This time that one hour episode encoded in 15 minutes. Watching Activity Monitor showed all four processors running at about 40% mostly in (nice) mode. The nice mode is good so that you can continue to use the computer for other tasks while it is working.
Obviously, it has a lot to do on the software. Both were Universal binaries, so I can't blame Toast's speed on Rosetta or anything else... -
High CPU Usage On client application when upgrade remote SQL database
Hi,
Is anyone here encountered very high CPU usage after upgraded the database from SQL 2005 to SQL 2012? Following describes my issue.
I have my client application running on Windows 7 that access to central database (SQL 2005) on Windows server 2003 using ODBC connection, this client application basically query data and perform data insert and update. There are a number of this similar
clients connected to the database.
Due to slowness of the database server, company decided to upgrade the database server to SQL 2012 and also new hardware runing Windows Server 2012. There is no change on the client application and client hardware and the client application still using the
same ODBC connection to query, insert or update the new database server.
The problem I am now experiencing now is that my client PC where my client application running the CPU usage is very high almost hitting 100% when accessing to the central database. I am also noticed this program lsass.exe that utilized almost 40-50% of
the CPU time when client application accessing the central database.
Is anyone here know, why client PC CPU usage 100% when access to upgraded SQL 2012 database? What is lsass.exe program doing, it only appear when accessing to database server. How to reduce the CPU usage on client?
Thanks.
Chee Wee.Hello,
After upgrading, please rebuild indexes and update statistics on the databases.

High CPU usage when playing flv files with flash
As more and more FLV videos are moving to HD, I'm noticing
high CPU usage and lots of dropped frames when playing FLV video in
web browser with Flash 10. This is true even if the video isn't
full screen. I've tried a variety of browsers (Firefox, I.E.,
Chrome) and the problem occurs on all of them so it's pretty clear
it's a limitation in Flash.
Now my PC isn't high end (it has a Pentium M 1.86 GHz
processor), but I can take those same FLV files and load them in
something like Media Player Classic or Windows Media Player (when
using ffdshow) and play the FLV files full screen with little or no
drop in frames and an acceptable CPU rate.
This is especially annoying on sites like YouTube where I
actually have to save the video and play it back in something other
than Flash to have it play back at an acceptable rate. This doesn't
work for other sites like Amazon.
Why is the CPU usage so high when decoding and displaying
videos when compared to other media players?I've been doing research about this excessively high CPU usage problem (100%!) for weeks because I have also experienced it with my vista home premium laptop. Just recently, I have finally found the solution. The problem is not your browser or your OS or your pc's memory. The problem is caused by authorization for flash player.
Read the link (posted below) carefully and follow the steps accordingly. If you have already done steps 1 through 6 with your computer, you can go straight to step 7.

PS: I am not the author of that link, so please thank the respective site owner if you find the procedure very helpful.
Please let me know also if the link solves your problem. I am sharing this because Adobe seems unable to provide solutions to this, and I don't want to hear people suffer.

Feature request: Monitor, manage IE - CPU usage
I was wondering if this is the right place to make a feature request. As it happens when surfing with IE, having many tabs open, pretty quickly CPU usage can reach 100% even on multi core system. Presumably some website manage to run out-of-control scripts
in the background.
The real problem is now that I cannot tell which tabs produces which CPU load. All that task manager shows is the IE process with the tabs and the overall CPU usage for the process.
Regarding monitoring it would help to identify the tabs (website) which cause the heavy load. This could be added to task manager.
Further, to manage the tabs it should be possible to either start each tab in its own process
or perhaps better, have the ability to put unused tabs in 'hibernation' causing all scripts to pause there.Hi,
you can post 'feature' requests to the IETeam at
http://connect.microsoft.com/ie
Task Manager in current windows versions lists all IE Tab processes.... Sort the process list by cpu usage to identify hungry tabs.
Typically high cpu usage is caused by
Web browser addons, incorrect browser settings (use gpu instead of hardware rendering) and flash or poorly designed websites or missing updates to your windows or third-party software. You may like to try running your browser in noAddons mode to see if that
makes a difference in cpu usage.... and also ensuring that you have enabled Windows Updates and that your computer has the latest updates from MS, Adobe etc.
MS has no control over what addons a user has or installs on their machines.
Post consumer questions about IE or windows to
http://answers.microsoft.com (Help>Online Support menu). Include with your questions the full links to any websites that you are having issues with....
Always... the first step in troubleshooting web browser issues is to test in no addons mode.

We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high.
This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure.
Below I provided some outputs that might help to diagnose it
Thanks

I was aware of the many ACLs however we used to have the same ACLs in a previous 3750G stack about 2 weeks ago and we never had this issue. I agree I need to optimize them and do somehing because it is reaching its max before the CPU starts processing them but I am not certain this is what is causing the issue.
Nikolay,
I am trying to understand "interrupts" with the analysis of the outputs I posted. Here is another output deom the link you provided. Please post your thoughts if you can.
This switch also serves as a gateway(L3 role) for many systems. Would it make sense to offload that responsability from this switch and let an actual router do it?
Thanks
Johnny

Complete Board Id:0x00B2
=========================================================== -
this is about an app that i use, not one i am developing, i am just trying to see if i can help out the developer or see if he has really tried 'everything' to optimize the app. This app does some heavy duty signal processing, it receives a very high speed
usb data stream from a custom device, it uses about as much of the usb 2.0 bandwidth as it can passing in pre-processed spectrum sampes. Then the computer side app takes that and does more processing to find and extract the data that it is supposed to work
on. I am running it on a win8x64, I7 box with one socket, 4 cores, virtualization enabled, and 8 logical processors, 8gb ram and nothing else doing anything significant... the app only takes about 50% of the cpu time even though it is not finishing processing
one block of data before the next arrives, this results in it automatically cutting back on the data decoders to process fewer signals until it can complete the processing before the next data arrives. I am watching the cpu usage in the task manager
or the resource monitor or the performance monitor and see about the same thing, but i suspect that the cpu is actually busier than those are showing, for instance if i show the kernal time in the task manager it seems to be hanging about 25%, does that
account for receiving the usb data and putting it in memory? or would that be done by hardware and not require cpu cycles?? is there any way to monitor background activity that might be using the rest of the cpu time? the developer says
he tried all sorts of things to get higher cpu usage but couldn't get it much higher, even if running the threads in real time priority. are there any unusual pitfalls or built in limitiations??Well you are asking us to do the dev's job while you don't even know what the job is. If the dev needs help (a big if, it seems the dev knows what he/she is doing) then the dev can ask here with specific goals (e.g. what part of program can be paralleled
to utilize idle CPUs), with details about the architecture of the program (which you don't have).
Also such rewriting comes with risks of breaking stuff that are already working besides labor cost. The dev may decide it is not worth the rewriting if the cost is too high compared
benefits to the user, just saying.

Satellite T130-10T: High CPU usage for non apparent reason
I have a brand new Satelitte T130.
From unboxing, I remarked that CPU usage is most of the time very high, even when doing nothing (no applications are running).
It sometimes hits 100% and stays ther for a few minutes.
I installed the newest BIOST I could find on the Toshiba site, but nothing changes.
Any ideas?
I don't like this just-out-the-box-unit already causes troubles!Hi mate
There are a lot of applications which are running in the background.
Most of them are installed by Toshiba and such tools controls the notebook features like FN buttons, multi control buttons, eco button, etc
You can see the ruing applications in task manager. There you can also see what background process needs the CPU usage.

Why animation keeps breaking even though CPU usage oscilate between 60-90%?
I made a simple animation.
In standalone player there is no breaking, but in browser every few seconds it stops and jumps, even though through all the time CPU usage never exceeds 100% but oscillate between 60 and 90%.
I tested it on two machines, both dual core above 4 GHz and result is the same.
Any ideas why and what to to to fix it?

S.J.this is an excerpt from one chapter (optimizing game performance) of a book i wrote (Flash Game Development: In a Social, Mobile and 3D World), and is intended to show this is not necessarily a simple topic amenable to a forum-fix.
Optimization Techniques
Unfortunately, I know of no completely satisfactory way to organize this information. In what follows, I discuss memory management first with sub-topics listed in alphabetical order. Then I discuss CPU/GPU management with sub-topics listed in alphabetical order.
That may seem logical but there are, at least, two problems with that organization.
I do not believe it is the most helpful way to organize this information.
Memory management affects CPU/GPU usage, so everything in the Memory Management section could also be listed in the CPU/GPU section.
Anyway, I am going to also list the information two other ways, from easiest to hardest to implement and from greatest to least benefit.
Both of those later listings are subjective and are dependent on developer experience and capabilities, as well as, the test situation and test environment. I very much doubt there would be a consensus on ordering of these lists. Nevertheless, I think they still are worthwhile.
Easiest to Hardest to Implement
Do not use Filters.
Always use reverse for-loops and avoid do-loops and avoid while-loops.
Explicitly stop Timers to ready them for gc (garbage collection).
Use weak event listeners and remove listeners.
Strictly type variables whenever possible.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Replace dispatchEvents with callback functions whenever possible.
Stop Sounds to enable Sounds and SoundChannels to be gc'd.
Use the most basic DisplayObject needed.
Always use cacheAsBitmap and cacheAsBitmapMatrix with air apps (i.e., mobile devices).
Reuse Objects whenever possible.
Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.
Pool Objects instead of creating and gc'ing Objects.
Use partial blitting.
Use stage blitting.
Use Stage3D.
Greatest to Least Benefit
Use stage blitting (if there is enough system memory).
Use Stage3D.
Use partial blitting.
Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Do not use Filters.
Use the most basic DisplayObject needed.
Reuse Objects whenever possible.
Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.

Why CPU Usage showing spiky line when Demand showing a smooth line?
I always thought that CPU Demand should be identical with CPU Usage, because both are average. So the chart below comes as a surprise to me. This is from vCenter 5.5 Update 1. There is no contention, as can be seen from the Entitlement counter.
The values are actually the same. The Demand line is somehow an average of the Usage. When both values are rolled up to 5 minutes, they become identical. The data at vCenter Operations shows that.
Question: why is the line pattern so different? The Usage showing a spiky line while Demand shows a smooth line. The Demand line makes sense as it is an average of 20 seconds. The Usage is a bit strange as it fluctuates drastically.
Thank you
e1I had a discussion with a friend on this. The 2 counters are both average, and are tracking the same thing. One of them has to be the "wrong" one. We think the CPU Usage pattern is the misleading one, because each sample is 20 seconds. That is 20,000,000,000 nano seconds. There are also 2 low point for 1 high point. It is strange for a CPU to be low for 40 billions nano seconds, then spike for 20 billion nano seconds.
The chart is from vCenter 5.5 Update 1. The host is ESXi 5.5

Why does SCHDNEGACTION scheduler job have high CPU usage?
Hi,
In my embeded device(double CPU 1.5 G HZ ) SCHDNEGACTION scheduler job has 90% CPU usage. Why does the scheduler job have so high CPU usage? What is the job doing for?Hi,
This job is not created by the scheduler. You will have to find out what component creates the job and what exactly it does to figure out why it is using high cpu and what would be the effects of disabling it (which would prevent it from running).
Hope this helps,
Ravi. -
Why does plugin-container.exe hog so much cpu usage?
When FF is running with some application (ie flash or maybe shockwave) or some type of embedded function, the cpu usage for plugin-container is generally between 60 and 80 percent. This causes extreme lag and reduced functionallity. Quite frankly it is extremely annoying to have things run so slowly.
Somehow this bug came up on my radar yesterday later in the day: the first two comments indicate different plugins, and the third refers to the Acrobat plugin:
<blockquote>This seems to happen if Adobe Reader is used for displaying PDF documents (pdfjs.disabled set to true and Preferences > Applications > PDF to "Adobe Reader (in Firefox)").<br><br>Opening two tabs displaying PDFs and closing one crashes the other one.<br><br>Was able to reproduce with Firefox 36.0.1 and Adobe Reader plugin "Adobe Acrobat 11.0.10.32". When I tried to reproduce it later again in the same profile (or on Nightly and Beta), the tab didn't crash.</blockquote>
https://bugzilla.mozilla.org/show_bug.cgi?id=1113190
Sounds like your issue, but it's puzzling that they got a tab to crash and in your case only plugin-container.exe crashed. -
Why screensaver always causes my macbook 100% cpu usage
screensaver always causes my macbook 100% cpu usage, my mac is ok when i use it, but when i leave it once the screensaver starts to run, the cpu fan start to rock and roll my desk which seems the cpu usage achieve 100%, it will be ok once it come back from screensaver, can someone help me on that? Thank you very much!!!!

Another way Acrobat Pro X startup fails can be fixed - informational
I'd like to recount an experience here, which had the same symptoms as the long run of Adobe Activation system errors. The odd process to recover from those is still needed, but the cause of the initial failure here turns out to not be Adobe's fault.
