High CPU consumption with Pre 8

Why does Pre 8 continue to run after I close it?  Running Vista Home Premium OS.  Each time I shut down Pre, I notice that my CPU usage meter stays at nearly 50%.  I have waited overnight and the usage does not go down even though the computer is not being used.  I have disconneced from the internet and that does not help.  The only way I can get the usage back to the normal, idle, 1-2 % is to open Task Manager and shut down Premier Elements.
I have also uninstalled Pre, defraged my drives and then re-installed it.  No change.
All other applications close down when I tell them to.

Thanks again Steve.  I reloaded everything two more times and still have the same problem.  It seems that once I start Premiere the CPU will not come back to its normal rest value, no matter what I do.  Task manager still shows that Premiere is still running even though there is no other evidence that it is running. Once I stop the application with task manager, things seem to be ok.
BTW I did update to the rev suggested by Adobe and that didnt seem to make any difference.
Many thanks for your efforts.  I guess tech support will be my next avenue.

  • High cpu consumption with GRE over IPSEC

    Hi all,
         After applying a gre over ipsec tunnel on one of our branch office, we get high cpu consumption (average 90%).
    Tunnel is applied between Cisco 2851 (C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T2, (fc2) and
    Cisco CISCO2921/K9 Version 15.0(1)M3.
    Config of the tunnet is as follow :
    - authentication pre-share
    - encryption aes 256
    - hash : sha
    - transform set : esp-aes esp-sha-hmac mode transport
    Routing process is eigrp.
    Could anyone please help me on solving this issue?

    Cool, good start.
    Check "show ip traffic" on both sides, it would be interesting to see what's going on.
    BTW the CPU usage of top process doesn't add up to 90%, there's a possibility it's traffic rate/pattern + features (IP input and pool manager would suggest that).

  • High CPU consumption with repaint while dragging

    Hi! I certainly hope someone can help me with this. I am building a graphical user interface for a graph with custom nodes and edges, the nodes being draggable. I have tried making each network component (node or edge) a JComponent. Now, I'm trying using only one JPanel to paint all the components. Either way, I find that dragging takes up too much CPU % especially when using full screen graphics, usually around 92%. And that is on a machine with >1.9GHz.
    It does not really make much of a difference when I paint outlines of the components while dragging. Any ideas about this? Thanks.
    My runnable test code is rather long so I've uploaded it to : http://web.mit.edu/jabos/www/SyncTest/GUILoad2.java.

    Comments about changes to your code:
    1 - trouble in rendering with setOpaque(false). Set this to true and add super.paintComponent(g) in paintComponent to take care of background paint updates
    2 - had to doctor your ConnComp class; the constructor was under construction...
    3 - I'm using j2se 1.4 so I converted your:
    ArrayList generics to the old Object casts and
    the JFrame setPreferredSize to setSize
    This runs okay now. The highest cpu usage numbers I saw were 52% in full screen and 37% in regular mode (2.6 GHz).
    The painting part seems okay; I think the trouble is in excessive data storage and manipulation. I would re–design your program to eliminate all the type checking with the instanceof operator. Specifically I would try to use only one ArrayList for the node objects and draw the connection lines between them inside paintComponent depending on how a boolean is set, eg if(showLines). As an aside, GradientPaint is for fill operations and will not benefit your line display.

  • I keep getting a box that pops up saying "High CPU useage with Firefox". What do I do?

    Sometimes a box pops up saying "High CPU usage with Firefox".
    I'm not sure what to do or if this is harming my laptop.

    Well i tried the Microsoft Malware and everything is fine on this end and you are still crashing on me so with that said,i am giving you one more day to resolve this issue if i still get crashes from you i am sorry to say i will have to try another company as my browser and see if i have an issue with them if i don't,i will not be reinstalling Firefox again if i do,then it may be another issue so i will have to see but i have no Malware here but thank you for your response anyway...

  • 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.

  • What does com.apple.cts.plugin do? It seems to be causing high CPU consumption by UserEventAgent

    I have been having some trouble over the last couple of days with UserEventAgent process. It constantly consumes over 100% CPU. This of course results in obvious problems of the unit getting really hot, high CPU fan speed and faster battery drain.
    While investigating the root cause, I removed each of the plugins (located at /System/Library/UserEventPlugins/) one by one and restarted the UserEventAgent process (if you force quit the process, it restarts) and each time, observed the impact on CPU consumption.
    After a while, I was able to zero down on "com.apple.cts.plugin". If I removed this file from the plugins folder and forced UserEventAgent to restart, my CPU usage went back to normal with no excess heat or high-speed fan.
    While it seems to solve my problem, I am left wondering what this plugin really does and if by not having it I am putting my system at risk.
    Any help would be appreciated.

    I learnt this the hard-way as well. I am not too sure but probably it has something to do with cerification authority or something like that. BTW I am looking for the answer as well.

  • 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.

  • High CPU usage with Coherence 3.5.0 cluster node

    We're noticing sustained high CPU usage on one of our Coherence nodes - this happens after running a job that pretty intensively interacts with the cache. The jobs complete, however we still see the Coherence process using approximately the equivalent of one core's worth of CPU. I took a couple of thread dumps about fifteen minutes apart, and the only noticeable differences are within the PacketListener1 and PacketListenerN threads - they're holding locks on different DatagramPacket instances, which suggests to be that this may be the piece of code that is looping.
    There are two other cache nodes in this particular cluster - both of them on a different machine - and neither of them are exhibiting the same CPU utilization.
    Environment:
    Coherence 3.5.0

    Has anyone encountered this scenario before?
    Here's a copy of the two thread dumps:

    ===== END OF THREAD DUMP ===============

    Charlie, Cameron,
    Thanks for following up. To answer Cameron's question - yes, running top shows that it is this process using a significant amount of the CPU. I captured a JRA this morning setting nativesamples=true.
    I see the following when I look at the Hot Methods - let me know if there is something else that would shed some more light on this issue.

  • Problem... High CPU load with HDD. Please Help

    Hello all,
    Im stuck. Ive got a MSI KA790GX which has poor HDD access/transfer, low burst rate and very high CPU load.
    As far as i know the Western Digital 640gb WD6401AALS Black should be a fast hard drive. Which according to reviews/HD Tune,
    should be:-
    Minimum 60mb/sec
    Maximum 120mb/sec
    Average 95mb/sec
    Access 12ms
    Burst 110mb/sec
    CPU 5%
    No matter what I try, i always get poor results...
    My MSI KA790GX
    Minimum 41mb/sec ~ 54mb/sec
    Maximum 104mb/sec ~ 108mb/sec
    Average 86mb/sec ~89mb/sec
    Access 12ms
    Burst 60mb/sec ~ 80mb/sec
    CPU 26% ~ 44%!!!!!!!!
    I could accept not getting the same high speed results as the review/reference, even if the burst rate sucked.
    But one of the cores goes to 50%-60% load during hdd activity. Thats just crazy!!
    I have tried...
    IDE mode, AHCI, RAID Ready, RAID Single Disk
    SATA Port 1, 2, 3, 4 + 5
    Different SATA cables
    Flashed bios, cleared bios, optimised defaults, failsafe defaults
    Windows XP 32bit, Vista 32bit, Vista 64bit. fresh installs
    MSI CD Drivers, MSI Web Drivers, AMD/ATI Web Drivers
        ... and combinations of.
    I have also tested the WD640gb Black on another older PC, with Nvidia (55?) chipset and slower (1.9ghz x2) cpu.
    Transfer rates were slightly better than my KA790GX but, Burst Rate = 115mb/sec and CPU usage = 13%.
    I also tried a Seagate 1.5tb (ST31500341AS) on both PCs,
    Nvidia chipset
    Minimum 65mb/sec
    Maximum 134mb/sec
    Average 107mb/sec
    Access 14ms
    Burst 83mb/sec
    CPU 7%
    On my MSI KA790GX
    Minimum 55mb/sec
    Maximum 120mb/sec
    Average 100mb/sec
    Access 14ms
    Burst 87mb/sec
    CPU 33%!!!!
    Could someone please please help, ive spent hours and hours on this. Its doin my head in.
    I just hope its something stupid ive missed, cos i still not used my HD4850 from christmas :-(
    Thanks.

    Not sure how to check PIO/DMA mode on a SATA device. IDE devices show DMA enabled.
    BIOS version 1.4 - 29 December 2008, and now version 1.51
    Fredrik
    I have Vista 64, but i did try XP32 and Vista32 and got similar poor results.
    I tested HDD speed with, HD Tune 2.55 and HD Tune 3.50 trial.
    No auto-start programs really, Windows clean installs + any drivers.
    Quadrifoglio Verde
    CPU @ default 2800mhz, All mem bios options to auto/defaults
    Windows Experience Index, CPU Score = 5.3
    AMD Overdrive
     Integer Computation = 8220
     Floating Point Computation = 5325
     Memory speed = 1770
     Cache Speed = 10790
     System Performance = 7403
    Bas
    I used HDTune because I could reference to other results. Whats a better program to use?
    Windows Experience Index, HDD Score = 5.9.
    But I have no reference and cant be sure of cpu load.
    Sepher
    Bios defaults to C&C and C1E off so i have tried them. Also windows power settings, balanced/high performance.
    UPDATE
    Reinstalled Vista64 but loaded the AHCI driver from the disk config screen. This seems to have stopped the high cpu usage during disk activity.
    HDTune with Windows Power settings @ High Performance,
    Min = 52mb/sec
    Max = 106mb/sec
    Ave = 88mb/sec
    Access = 12ms
    Burst = 77mb/sec
    CPU = 3.4% 
    HDTune with Windows Power settings @ Balanced
    Min = 54mb/sec
    Max = 104mb/sec
    Ave = 87mb/sec
    Access = 12ms
    Burst = 65mb/sec
    CPU = 12%
    So now transfer speed is about 10% slower than reference. But burst speed is terrible.
    I also used IBM Feature Tool to change the HDD AAM to 'performance mode' 254 as suggested elsewhere.
    Long shot as the hdd performs ok with other hardware. same results.
    Also MSI support asked me to try a newer bios, version 1.51. same results.
    Anyone know what the AMD 7-Series Chipsets Disk Performance Utility does, and should i run it in Vista64?
    Thanks for all the replies, hope i can sort this, not played any PC games since Quake 3 on my ti4600...

  • High CPU Usage with Flash Player 11

    I am not sure what the problem is but ever since I had those issues I went back to flash archive and installed a previous version that did not come with the flash plug in and I never had any problem with it since I am currently using the Adobe flash version 10 plug in with an adobe flash player active X. and I find out it was the new flash plug in that is the issue it suck all your ram. If you get some people who is having the same issues where flash player is duplicating and eating all their ram then ask them to try the version 10 plug in with the flash 11 active x it will work fine. I tried to run the version 10 flash as a complete set but some dynamic site that plays videos require a later version of flash active x to work and will be asking for an update however by keeping the flash 10 plug in there won't be any other issues. Adobe need to find out what is wrong with the new flash plug in and run a comparison with the flash 10 plug in. I hope this will help some user to get over the issues that made my online experience a nightmare for a while too.

    The best way to get a resolution is to address your individual issue.  Your complaint is that RAM usage is high, which is unrelated to the thread from the guy on Mac that was seeing High CPU usage on high definition video.
    In order to fix the issue that you're describing, we need to be able to reproduce it.  Please provide the information below, and the results of the basic troubleshooting steps as you work through them.  This will help us narrow down the root-cause, and allow us to find comparable hardware in our compatibility lab to reproduce the issue with.
    Basic Troubleshooting Info
    To help troubleshoot we'll need the following system information:
    - Operating system
    - Browser
    - Flash Player version - http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
    - Antivirus/Anti-Malware software and versions
    The first step is to work through the video troubleshooting guide for your operating system, here:
    - Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html
    - Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.htm
    When reporting issues with video or audio, it's also helpful to get your system hardware and driver details.  Instructions for finding this information can be found here:
    - Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Windows_users
    - Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Mac_OS_users
    Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player.  I recommend trying both of the links below to see how they perform.  If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing.  You can verify this by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the menu.

  • EA2: high CPU usage with large packages

    EA2 + Debian GNU/Linux + jdk1.6.0_04 + Pentium IV 2,8 GHz 1 GBytes RAM
    Opening large packages (> 6.000 rows) I have high CPU usage (100%) for about 50-60 seconds. Same problem when I working with these packages
    Ciao
    Davide

    Opening works fine for me, and memory seems to be
    contained. Working inside the package on occasions
    still boosts CPU like you.Attempting to edit an 800 line type body utilises 100% CPU as soon as typing starts.

  • Unusually high cpu usage with iMovie 6.0.3

    I'm having trouble with very high cpu-usage. Just the open imovie app is taking up about 50%, during playback it sometimes peaks over 100%! The project file is pretty big (about 30 gig), but that is mainly because of the amount of footage imported into it. The movie itself is about 25 minutes in length. There is some audio editing going on: some soundeffects, musicfiles (no drm-protection), audio commentary that i recorded within imovie. I know that imovie has trouble when there is a lot of audio/audio editing involved and this project is probably a little more complex than other stuff i did in imovie, but i never had such problems. i can hardly use playback anymore. I recently updated Quicktime to 7.6.4 and Perian to version 1.2.1. Any ideas what's going on or how to work around the problems? Since the movie is about 80% finished i don't really want to start all over again. Thanks in advance for your input!

    Hi Klaus1
    I have several plug-ins by cfx and the slick volumes 4, 6 8 and 10. I can post a list of all of them if you like. Up to now they never made any trouble, but you'll never know...
    The edit in the timeline is about 25 minutes long. But the project file contains captured dv-footage of about 2 hours, so that alone adds up to something like 26 GB. Then there are a few rendered effect-clips done with some of the plug-ins like stabilizing or color correction which also add to the 30 GB, as well as some audio-files (some music, my voice-over commentary). I emptied the trash several times while working on the movie. At this moment there are only a few MB of erased audio in it.
    It all sounds a bit like this is an insanely huge and complex project, but as i said, i have done projects like this in imovie without the massive cpu-usage. I'd like to continue to use imovie, but if this problem keeps coming up with future projects, i might as well take the step and switch to Final Cut Express.
    For now I will try your idea of exporting the movie as it is now and open it in a new project file.
    Thanks for your help and input so far!

  • Too high cpu load with HP 6510b

    Hello guys,
    I have a very high cpu load on my laptop even if nothing despite htop is running. I guess it's a problem with acpi because when I deactivate acpi completely over the bootline I have no such problems.
    How could I fix that?
    Thank you in advance.

    Hello B,
    unluckily noacpi doesn't help but acpi=off. That seems to be the only way to stop the high load.
    Is there any patched acpi or something else?
    I also think I picked the bad revision with fan problems and some more...

  • Firefox 6 has high cpu consumption

    Hi,
    I have just upgraded from Firefox 5.x to 6.0. I am using Windows 7 32-bit on a Dell Laptop, Core 2 duo, 4 GB RAM.
    I have observed that FF seems to consume a lot more CPU than before.
    Also, the memory footprint keeps changing rapidly. I don't have a physical memory issue.
    The worrying factor is intermittent but unpredictable recurrence of high cpu usage when i open a new site, etc.
    Adobe plugin does work but it is a bug CPU hog.
    Please help provide a resolution as it seems like going back to 5.x is a better option at the moment since i didn't have much of an issue with FF 5.x.
    Thanks,
    Anand

    Same symptoms as well. Have tried starting in safemode, disabling addons etc. as detailed in solutions elsewhere on this site, but the problem remains. Have completely uninstalled and reinstalled Firfox as well, but no good.
    The problem happens instantly whenever I open a link in a new tab or have multiple tabs. The high load (95-100%) does not reduce from this point on and the only solution is to kill Firefox. I'm running XP SP3 on AMD 64 platform.
