File copy results in kernel task high CPU usage

Copying files over the network, or via external Firewire 800 harddrive invariably results in rather hight cpu utilization for kernel task process. The number are in the range of 15-20% in the Acivity Monitor. To compare, iMac 27", 2009, full speed FireWire bus file copy at 80 mb/sec makes only 2-3% kernel task CPU use. Why is Macbook pro so much worse? Is it due to chipset limitations, or what?

Just now I have been copying some movie files over Gigabit local area network, the data received per second is up to 55 mb, and kernel task consumes 50% or more of CPU. The same task on iMac or on Windows based computer does not tax the CPU in any way, since it is handled properly by network adapter I suppose. So what is wrong with 2010 Macbook Pro?

Kernel task high CPU usage?

So I noticed my macbook pro (17" 2011, 16GB RAM) running slow, especially graphics. opened up the activity monitor, and lo and behold there is something using 283% of my CPU: kernel_task. Before I even ask how this is possible, what is kernel task, and could this be responsible for my sluggish machine?
I did notice a week ago that google chrome is allowing many pop up windows with messages trying to get me to download system checks and other nonsense... Not sure if this is related but that's annoying too.
Any ideas?
Thanks

ALso, restarting does nothing to alter this slow state it seems. Restarted twice with no improvement

Kernel Task 350 % CPU usage...

Hey guys... ive a big problem with my macbook pro 13 eary 2011...
since yesterday evening its very very slow and my fans are allways at 100% fan speed...
my problem is that it start directly after the start...
i turn on my macbook and my fans go full power and my macbook is slown down...
what did i try..
smc reset by clicking (left) + alt+ctrl+shift and powerbutton... nothing happened...
reinstalled my mac osx 10.7 (needed 3 hours for installation)
do u have some tips for me? i dont know anymore...
in the first moment ive watched series and then ... fans full speed and slowing down...

The kernel is using excessive processor cycles. Below is a partial list of causes for this condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to a buildup of dust on the logic board, to high ambient temperature, to a worn-out or faulty battery, or to the malfunction of a cooling fan or sensor. Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board.
The Apple Hardware Test, though not very reliable, is sometimes able to detect a bad fan or sensor.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or booting in safe mode. Note, however, that disabling a system modification without removing it or booting in safe mode may not be as easy as you think it is.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
Peripherals
According to at least one report, connecting an external display to a MacBook Pro via a Thunderbolt-to-DVI adapter may cause this issue. I can't confirm.
Encryption
Transferring large amounts of data to or from an encrypted disk image or FileVault volume may put an extra load on the kernel. If both the source and the destination are encrypted, the load may be doubled. If you transfer data from an encrypted disk image on an encrypted partition to another such image on another encrypted partition, the load may be quadrupled.
This issue probably doesn't affect late-model Macs with an Intel i-series, recent Xeon, or later processor. Those processors support hardware-accelerated encryption. You can determine what kind of processor you have by selecting About This Mac from the Apple menu in the menu bar.

High CPU usage when downloading Files

Hi there,
i noticed somethign strage when I download file off the internet or intranet. As soon as my download speed surpasses 1MB/s the CPU usage increases. To be exact the process kernel_task.
For example:
2,5 MB/s -> ~30%
10 MB/s -> ~60-70%
10+ MB/s -> ~80%
This is really annoying and I have now clue how to fix this. The Harddrive is a SAMSUNG HM320JI with a Journaled HFS+ partition. No Virus Scanner or anything. Also just reinstalled Snow Leopard yesterday.
Hope someone can give me some useful information how to fix this.

Hiya,
could it have something to do with the write speed/ cache/ram? On a "slow" disk, or one that is nearly full or one that is partitioned, it will take a great deal more ram and cache to "digest" the faster download and write it onto disk. I tend to do downloads to a separate drive. Have you got one? and can you repeat the high CPU usage when downloading / saving to the external drive? I note your drive might have 5,400 rpm, with "just" 8mB cache and 320 GB (quite a few SATA's have 7,200 rpm and 32 mB cache).
NB: If anything, I found SL more efficient, especially on my 4 year old Macbook, which is running much faster and has got more responsive after installation of (full version of) SL.

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.

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.

Database file + high cpu usage

this has only started happening since i formatted and reinstalled windows. i have tried using both itunes 6.0.2.23 and 6.0.4.2 and both have the same problem.
my music library contains 5088 songs, i have tried deleting heaps down to around 3400 and problem is still there (ie i have eliminated number of songs as a factor cause before formatting i had more than 3400 but less than 5088)
when i play a song in itunes after about 5 seconds my cpu usage will jump to 100% this is on the "system" process, itunes itself uses around 2-5%. i was watching the itunes music folder though, and what it is doing is creating a new temp file (of 7.27mb) then renaming it to replace the current "itunes music library.xml" file. as soon as the xml file is replaced (takes about 10 seconds) cpu usage returns to normal.
this exact same thing happens when i quit itunes, although it takes roughly 20 seconds.
i have tried deleting all files in the itunes music folder apart from the base database file, that did nothing.
i tried removing the entire folder and letting it create a new blank library, then added just 1 album, and it worked perfectly. i also noticed that on my original library most but not all AAC encoded files did not cause the cpu spike, all mp3s did.
i tried creating an entire blank library and adding all my music back in, it still did high cpu usage so i would assume my current database is not corrupted.
does anyone know a solution to this? how to stop it recreating the xml file with every song played. the only thing important to me is saving my playcounts, so any solution which does not require losing them would be appreciated.
also yes i have tried completely uninstalling itunes, for both of the versions mentioned above, also tried updating over the top of the current installation, problem occurs everytime.
i am running service pack 2, all current windows updates installed, no spyware, no viruses.
thanks.

It may be iTunes, but it probably is not. iTunes is just affected by a conflict with another program (possibly).
Do you have a spy sweeper/virus scanner/etc. that periodically scans your PC memory? If so, then that is what may be interacting with iTunes.
You should list the iTunes Folders as part of the exclusions within your Virus Scanners, and other Security software.
BTW: I have a Library with over 13,000 song references. I do not see the same CPU spikes when playing music. It's not the size of the database - not at your current level.

High CPU usage when editing large MXML files

I am using Flash Builder 4.5 Plug-in on OSX. When I have a large MXML file open, Eclipse will consume 100% of the CPU as long as that file is open, even if I am not doing anything. If I close that editor the CPU usage goes back down. I've seen this in Flash Builder standalone as well as the plugin. Is there a workaround to stop this CPU usage problem?
Thanks

High Cpu Usage when file open in Illustrator 9

Hey guys, have had a few problems lately when an EPS or AI file is open in Illustrator 9.0 cpu usage sits between 50 - 100% and clicking around the program is in general very sluggish. All boxes with problems run Windows 2000 SP4. These arn't slow machines either, about 3GHZ dual core, 1GB ram. I know Illustrator 9 is old but it's being used in a business environment so upgrading is not really an option. Thanks in advance for any help.

By "lately" do you mean this is something that started happening recently?
If so, can you remember any changes (updates, service packs, other software, etc.) you might have made to your boxes recently?
Are you updated to 9.0.2?
If not, it's worth doing, and here are the pertinent links:
9.0 to 9.0.1
http://www.adobe.com/support/downloads/detail.jsp?ftpID=1100%3E%3Cu%3E9.0.1%20to%209.0.2%3 C/u%3E%3C/a%3E

SBS 2011 - High CPU usage - Help me Microsoft forums! You're my only hope!

My company supports a client that has a SBS 2011 server. For about the past year, we've been fighting a recurring issue with performance on this server. There are about ten local users and four remote users. The server's CPU idles at
about 60%-80% but is usally running when under *any* load from 80%-100%. If you do anything on the console, it will stay pretty much at 100%. These are not power users by any means. The server is utilized for file/printer sharing, Exchange
2010, and one flat file database application (non-SQL). SharePoint is not utilized.
Needless to say, our client is frustrated. When opening files, using their database application, or doing anything Exchange-related, there is a large amount of lag on the client side. First, here are the server's specs:
Make:Dell PowerEdge T420
OS: SBS 2011 Standard SP1
CPU: 2 - Intel Xeon E5-2407
Memory: 32GB
RAID: RAID 1 - Operating System (C:)/Data Volume (E:) | RAID 5 - Data Volume (D:)
Here is what we have tried to resolve this to finality:
* Doubled resources - Initially the server had a single physical processor and 16GB of memory. While these specs alone should have been fine, and were fine when the server was installed, we had periods of time where the server would just sit all day at
100% usage. We doubled the resources and while this seemed like it would fix the issue, we are still seeing abnormally high processor usage.
* Removed all monitoring tools, antivirus, and backup software - As part of our testing, we removed our monitoring agent (LabTech) and antivirus (GFI Vipre). Mozy is utilized for an off-site backup so that was disabled. No dice.
* Verified updates - We made absolutely sure the server was 100% patched.
* Malware/Virus/Rootkit checks - We have ran scans checking for any potential issues with security.
* Ran MBSA and MBCA to fix any issues with the server's configuration.
There is no single process which is using all of the CPU, or we would simply be able to narrow it down. Our calls to Microsoft support have yielded no answers. The last call ended with Microsoft stating that a SBS server should always be running
at high CPU usage. Meanwhile, we have many other clients with less-beefy servers, with more users, who have no issues like these.
So, I'm turning to you all. I will gladly provide logs, configuration settings, even remote assistance sessions if you all can help shed some light on what might be causing my issues.
Thank you!

Some comments/ideas:
How long was the server running after this screenshot? I ask because store.exe is only got a 1GB of RAM which is really low - it should grab most of the RAM within a few hours.
The server was up for about 12 hours. I believe an adjustment was made before to limit the Exchange memory usage.
Strange that SearchIndexer (wsearch service) is so high although that may be a startup condition.
The LT* processes seem to be a 3rd party monitoring tool - no idea why it would ever need that much CPU though (I thought you disabled this?).
We had, but we cannot go forever without monitoring our client's server. It has been pulled off in the past and results on performance are pretty much the same.
The taskmgr process run by amnet_admin has used a lot of total CPU Time. What is it? (can't see the command line).
That's the user I was logged in as when I took the screenshot. Even the task manager seems to eat up the CPU.
The sqlserver process right above it is also busy - may want to look at the command line and figure out which SQL database that is (SBS has 3 - WSUS, Sharepoint, and SBS monitoring)
I believe that's the SharePoint database. They don't currently use their site. Would you recommend a removal and reinstallation? I would not completely remove as I know SBS doesn't like you removing parts of the complete package.
Strange that vds.exe is 10% - that is the interface to the disk management interface IIRC. Perhaps your monitoring service has gone awry here - definitely lose it.
I'll see about pulling it off and I'll see if there are any improvements.

While we're aware of the issue, there's not much we can do about it. The modern security realities facing web browsers have made sandboxing a necessity.
There's a good explanation of what's happening here: http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
Long story short, each video packet has to be passed from the browser to a medium-integrity broker process, then to the low-integrity flash player process for rendering. If an attacker manages to hijack the Flash Player thread, the process is low-integrity, which prevents the attacker from doing much with it. While it's not an absolute guarantee (nothing in security is), it raises the bar significantly for attackers.
The downside is that all of that extra message-passing consumes CPU cycles, especially if you're trying to fill an exceptionally large buffer as fast as possible. There's not a lot of opportunity to optimize this.
If you're fine with the risk, you can manually disable ProtectedMode on your machine. If you're only dealing with trusted sites, and you're not doing anything critical with the machine (work, banking, etc), then it's probably not a huge deal.
Ultimately, ProtectedMode is like a vaccine -- it's a herd-immunity thing. If the majority of people run it, exploits targeting machines without it are inconsistent and probably not worth pursuing when you look at the effort involved in developing an end-to-end exploit. If a large number of people disable it, it becomes economically attractive for people building botnets, and you'll have a problem if you're not using it.
To disable Protected Mode, add the following line to your mms.cfg file located in:
Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
ProtectedMode=0
If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
To re-enable Protected Mode, simply remove the line from the mms.cfg file.

High CPU usage in cisco 7613 with rsp720-3cxl

Hi everybody,
our cisco 7613 has about 4.5 Gbps Tx/Rx IP traffic in total, and we run ospf with other cisco cloud for routing I list in the following some our router show.what is your idea about our high cpu usage .Is it in normal range with the listed cards and modules.How can I tune the rsp720 and other SIP-200,400,600 for better performances
why our interrupt rate is high ,and one thing more the total sum of 5sec in separate rows not equal to cpu utilization for five second 50%

Continual HD activity, high CPU usage when idle

I got my first notebook, a Compaq V2000, a few weeks ago and have Arch set up pretty well on it but I have a few issues. Even when the machine is sitting idle it sounds like the HD is doing a read (or whatever) about every 5 seconds. This only starts after I log into Gnome and stops if I log out.
I tried a couple of things with hdparm:
If I try 'hdparm -y /dev/hda' the drive goes to standby but immediately spins up again.
'hdparm -B 255 /dev/hda' disables APM and stops the cyclic behavior. This would seem to be good but during the 5 second cycle the drive alternates between quiet and noisy and this leaves it in the noisy state.
I tried to determine what might be causing all this disk activity so I edited lilo.conf to remove "acpi=on apm=off" from the "append=" line and in rc.conf I put a ! in front of all modules and daemons and rebooted. I removed the applets from task bar. No change.
I ran top to see if I could tell what was accessing the HD but I'm not knowledgable enough to make much sense of it. I did notice that on my notebook the top summary shows:
CPU: ~30% user, ~10% system, ~60% idle with 'wait' bouncing between 0 and 5%
On my main computer, also running Arch/Gnome, I get
CPU: ~2% user, ~1% system, ~97% idle with 'wait' solid at 0%
On the notebook, if I run hdparm -B 255 /dev/hda the CPU #'s for user and system remain high but the wait # drops to zero and stays there.
I don't think all this HD activity could be good for my machine, and I know I find it very annoying. If anyone could help me stop all the HD accesses and understand the high CPU usage I would appreciate it.

I loaded lsof and frankly it scared me. It listed what looked like a couple hundred files and I didn't know exactly how to use that information.
Then I tried laptop-mode-tools. The man pages didn't sound too promising since it uses, among other things, hdparm, which I already tried with mixed results. I gave it a try anyway and right out of the box, with no configuration, it worked. HD access when idle dropped to essentially none, the drive spins down and the cooling fan runs much less frequently.
So far all I have changed in the config file are the HD idle timeouts. The default of 5 seconds was starting and stopping the HD too often so I changed that to 20 seconds for now.
Whatever laptop-mode did to stop the 5-second HD accesses the effect persists even if I run 'laptop_mode stop' and '/etc/rc.d/laptop-mode stop'. When I get the time I should be able to use 'laptop_mode status' and laptop-mode.conf settings to determine exactly what the magic bullet was.
Thanks, lucke. I never would have tried laptop-mode on my own because I thought it only duplicated functionality that I already had with hdparm and powernowd.

High CPU usage when updating or instlling s/w

When updating Win8 or installing MS Office system slows down and has to run all night to make any progress. Task Manager shows "System" using 49%. "go to process" shows "NT Kernel & System". The system was bought with Win7 and is now double booting both 7 & 8. Win 8 partition has 500 GB.

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

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.
