Acrobat very Slow performance (50% CPU usage)

My acrobat 9 PRO (9.3.2) has suddently started to use 50% of my CPU usage everytime a *.pdf document is opened.
It is the task Acrobat.exe which is the problem. This results in VERY slow performance and I cannot use the review function without adobe is crashing!
This has not always been a problem!
Does anyone know why this is happening?
I have tried to uninstall and reinstall acrobat, without any luck!
Thanks
Peder

You probably have the same problem as I do. I use version 9.3.3 on a fairly powerful machine with Windows vista. In my case, the problem is related to the weblink.api (http://forums.adobe.com/thread/675941?tstart=0). I also uninstalled, reinstalled, repaired - nothing helps.

  • Firefox very slow and high cpu usage!! (all other browse slow too)

    Sorry, I asked it in 'Newbie Corner' , but still no resolved. so I asked here.
    Hi all,
            when i open a website just as www.sohu.com,   my firefox (3.0.3) hang on, then display the web page very slow , and slow scroll , firefox cpu usage nearly about 100.
            I tried some sloution,like modify /etc/enviroment to set MOD_DISABLE_PANGO=1,
    or disable 'tell me if a web site ...' in firefox security option.
    but still slow.
    some people says it's must because flash or some js.
    but when  i try it in windows or ubuntu, it very fast, not like in archlinux.
    so i think some thing wrong in archlinux.  I need your helps.
    thank you.
    p.s.
    1.  pacman is very fast (the speed of wget about 400k/s)
    2.  gnome web browser like firefox , slow and high cpu.
    3.  the list of output of 'locale'  about 11 lines.
    4.  i have already set host name like wiki says.
    5.   the system is  a new system

  • Lightroom is very slow, utilizes 100% CPU, then freezes or closes program.  How do I fix it?

    I am having a problem with Lightroom 5 being very slow, utilizing 100% CPU, then freezing or closing the program.  How do I fix it?
    I just upgraded to LR5 from LR3 on Sunday as well as CS6 from CS5 (which I have not tried out yet).  I spent several hours talking with Vamil, from LR Support Staff yesterday.  He was extremely helpful and kind and tried everything he could think of while remote-handling my PC and talking with me on the phone.  He deleted preferences, cache, temp files, updated graphics with a new replacement file from AMD site, then re-downloaded and reinstalled LR5. 
    It is still very slow and then freezes and closes down with a message of utilizing 100% CPU.  Within several seconds of using the brush in Develop, I started having lots of problems.  I could not even move the picture around.  The side screens would not disappear like they should.  And I could not move to another picture.  The day before I spent several hours trying to work on just 1 picture.  After all the changes yesterday, I tried to move from picture number 1 to about 130 after having not touched it for 10 minutes, and a half hour later, it still said, "Processing" with no picture coming up, just a blank prieview pane.
    LR Support suggested I get a new CPU though he thought according to specs mine should be ok and other programs were running fine.
    My PC is only 2 years old.
    I talked to HP briefly about CPU updates for my HP PC.  He said I probably do not have a problem but suggested I run self-diagnostics and maybe buy a new CPU anyway. 
    I ran diagnostics listed through the HP Support Assistant connection on my PC.  All was ok. 
    I still researched if I could buy a compatible CPU upgrade.  I cannot even find any CPUs still selling that are listed for my PC.  Best Buy Store said they could not even order a compatible CPU.  They said my Bus speed may not be big enough, so they suggest I get a new PC.  What Bus speed do I need?
    I have the following PC Setup:
         AMD Phenom II X6 1045T Processor 2.70 GHz with 6 Cores
              with 2700 MHz Base, 3200 MHz Boost, and 4000 System Bus Speed, and 95 watts;
         HP Pavilion Elite, HPE-500y, 900 GB Free, new in 2011;
         Windows 7, 64 Bit;
         RAM 16 GB, DDR3;
         Graphics AMD Radeon HD 6450;
         Nikon, D200, with Raw Files;
         External Hard Drive for Original Photos, 600 GB Free;
         LR Catalog and Library are on Main Hard Drive;
         Monitor, Sony CPD-200ES, new in 2004.
    I am thinking of buying a new monitor tonight mostly so I can do better photo work while enlarging the pictures to do it.  I am concerned that while it will help my viewing, it will take more power away, and make my usage of LR5 even worse.  Will a new monitor affect my performance?  I am looking at HP Monitors with IPS.  Is this the best recommended choice for LR and Photoshop CS6?
    I think I would like to stay with a 6 core processor since I need to have several items open for other non-Photoshop functions.  When running LR5, I had everything else closed.  With LR3, I was able to have other things open.
    I do not really want to buy a new computer and know that those I have talked with at this point are only guessing after looking for what they thought should fix it.  4 People from Lightroom Support have all thought I should not be having problems with my setup. 
    I bought one of the best computers 2 years ago.  Is it really obsolete already so that I cannot use LR5?  Is everyone else buying a new PC every 2 years?  I used to go 5-7 years. 
    Even though I have figured out some of what my PC has, I really do not know technically what I am talking about so am at the mercy of other's help.  Are there any solutions that might work short of buying a new computer?
    I also have taken 40th anniversary photos for some people and am waiting to give them as a free gift since I am not a professional at all.  I am hoping to get through this problem soon so that I can provide some nice memories for them.
    I have not gotten any further than trying to adjust 1 picture.  I have no comments on uploading speed, since I did that while still in LR3.
    Thank you for your time and help.

    I'm running LR with no speed issues on an Intel 17-860 quad core with about the same performance as your AMD Phenom II X6 1045T Processor. My system is also an HP, which originally had a single 1TB 7200 HDD. I've since added a second 2TB Black Caviar HDD, which provided no significant difference in LR's performance.
    AMD processors do not implement hyper-threading and don't need it. I'd start debug by process of elimination:
    1) Disconnect all externally attached USB, FireWire, or other externally connected devices except keyboard, mouse, and your single 1280 x1024 display. This includes all externally attached memory card readers, phones, ipads, etc.
    2) Reboot and logon as Administrator.
    3) Remove your Internet connection and turn off all Antivirus and firewall programs.
    4) Open LR and under Catalog Settings set 'Standard Preview Size' to 1440 (slightly larger than your display width). Under the Metadata tab here make sure 'Automatically Write changes into XMP is NOT checked.
    4) Create a 'New Catalog,' Create a new folder and add about 10 raw image file copies to it for testing, and Import it into the new catalog. In the Import module make sure under File Handling 'Render Previews' has 1:1 selected. Wait until all Preview building has completed in the Library module.
    Try editing these image files inside the new catalog as you were previously.

    ok, stopped syncing in System preferences and even (horror) deleted the file which reappeared in seconds.
    now waiting to see if stopping the syncing helps - though computer is now working a bit better, the info on Activity Monitor would indicate it is not a real improvement

  • InDesign CC 2014 very slow performance when dragging images and changing text

    InDesign CC 2014 very slow performance when dragging images and changing text.
    Running on 2010 Macpro 2.4GHz. 8GB RAM. Any solutions? I've read through many forums on this and tried several fixes.

    Have exact same issue on  my Windows 7 machine. Resetting preferences is a workaround.
    So I start InDesign whilst holding down these keys.
    Ctrl + Alt + Shift (Windows) or Cmd + Ctrl + Opt + Shift (Mac)
    Whilst inDesign is usable again with this fix- I have to do it every time so it trashes all my preferences so NOT GOOD long term fix. Otherwise InDesign freezes and can only be stopped by forcing a quit.
    I have manually deleted the preference files and I have created a brand new admin account - but still no luck - will be onto support tomorrow

  • E50 very slow performance

    my E50 is giving very slow performance anyway to tune it up ?? dosn't hangs but its slow ?? any solution ps whats the best antivirus to install in E50 ?

    I don't use your same workflow, and I assume you're shooting RAW. However,  after I have built 1:1 previews in LR (which takes a LONG time), when I click on a file to decide if it's sharp or not, it still takes 5-10 seconds for each file to load. And my computer isn't slow, and I have the same issue on my laptop, which is new and fast. I haven't seen a satisfactory answer to this problem, nor much acknowledgement from Adobe. My files are from a Nikon D7100 with 24 megapixels, so the file size is likely a factor.
    If you are shooting the type of subjects where you use 1:1 previews primarily to determine sharpness, you could consider Photo Mechanic (unfortunately it costs $150) as the first step in your workflow. It uses the embedded jpg files in the RAW file, so it loads 1:1 jpg previews almost instantly. Sports and nature photographers use this product all the time, mostly to delete losers.

  • Formatted Search with DI  leads to a very slow performance - HELP....

    Hello There
    I have defined some formatted search in OPCH - everything is working fine.
    I have added some logic to this form via the DI.(handlling 1 item press_event), and I get a very very slow performance - the ADDON-EXE jumps TO 230MEGA of memory, and entering values to each row in the tables/item in the form takes about 15 seconds.
    Any suggestions?
    RGDS
    HAGAI

    Hi Hagai,
    Normally an addon written using the DI would take up 60-80MBs.
    Are you filtering out all events except for the item press event for the form? If you are not filtering events then this can have quite a drastic affect on performance.
    What logic have you got behind the press event? If the addon exe is ballooning out to 230MB then it suggests that there is either a problem with a memory leak or that an error is occuring in the code. I would recommend putting try/catch clauses at suitable places in the code and maybe specifically setting objects to null and calling the .NET garbage collector to try and minimise the potential for memory leaks.
    Are you sure that it is the combination of the formatted search and the addon that is causing the problem, i.e. if you take away the formatted search but leave the addon do you still get poor performance or does everything speed up?
    Hope this helps,
    Owen

  • Very slow performance in Lightroom 3??

    I just upgraded to Lightroom  3.0 and I am very suprised how slow it is!?!  I don't have a very large library and I'm on two reasonably new computers yet the difference from Lightroom 2 (snappy performance) to Lightroom 3 (VERY sluggish) is quite suprising..
    I'm using it on a XP and a Vista system with the same results...
    Is anyone else experiencing this???
    Thanks,
    Ken

    I've noticed a slow down in performance with Lightroom 3 as well. As far a looking around the forum for older threads, ...found older lightroom 1 and 2 threads.
    Your Title "Very Slow Performance in Lightroom 3??" fits what I'm looking for just perfectly.

  • KDE 4.7: very slow and high disk usage

    Since upgrade to KDE 4.7 on my i686 laptop, my system behaves weirdly. I noticed a slow down caused by a very high disk usage: when the HDD spins the cpu usage reported by the CPU monitor plasmoid is very high (~ 50%), while top reports a very small CPU load. Another strange symptom is that, when I try to close the session, the system freezes for about 15 seconds before the logout/shutdown/restart dialog window appears, again with HDD spinning furiously. If I exit the dialog window and then try to close session again it works smoothly, so I think some caching is at work at second try.
    This is very painful since it slows down my workflow. Since now I tried to:
    - disable nepomuk, strigi and all that using the nepomukcontroller plasmoid
    - disable compositing
    - delete .kde folder
    - uninstall and reinstall all kde packages
    without any benefit. On the same laptop I have dual boot with a 64 bit arch installation, which does not have the same problem, nor has it my 64 bit desktop pc.
    Does anyone have similar issues? I don't understand what is it that makes the HDD spin so much, nor how to eventually track it down (are there som HDD usage profiling utilities?). Moreover, why top and CPU usage plasmoid report so different CPU usage stats?
    I'm very confused, so any help will be greatly appreciated.

    Although I'm not having any of the issues as Snack, I have found KDE 4.7.0 to be a very horrible release. In fact, I'm sick and tired of the KDE release notes bragging about killing thousands of bugs each release, when in actuality the first few revisions of each stable release are horrible. When I first upgraded, I ran into at least four really nasty bugs. Although I've worked around some of them, it left a really sour taste in my mouth. Here is what I've experienced:
    1.) With a new user or fresh install, there is no wallpaper by default, even if I install kde-wallpapers before I log in, it makes no difference.
    2.) Sometimes kwin will crash during log out.
    3.) Worse yet, if I exit a full screen game, it will more than likely crash Kwin. This is a problem on my laptop (which has intel video) and not my desktop (which has nvidia video). If I don't remember to disable desktop effects before opening a game, I may run into a problem.
    4.) Although my performance is good, it's not great. I would think a laptop with a Core i5 processor and 8GB of RAM would run faster than it is.
    I have tested XFCE for a bit, and I do like it alot. However, with XFCE I am unable to browse Samba shares, and that is a huge problem. In addition, I find KDE's applications to be much better than what ships with XFCE, but I question whether they're worth the performance hit. I really love Kate, Gwenview, Digikam, and Amarok. I know you can install those in XFCE, but they feel out of place and then my desktop pretty much becomes a mutt. Not only that, but KDE is full featured, whereas XFCE is not. It's like I have to choose between a stable desktop or a desktop with full of bugs.
    I hope that KDE 4.7.1 fixes everything, but historically it's usually the 4.x.2 release that really does the trick.

    Lightroom's performance on my computer has become, at times, intolerably slow.  After rebooting my iMac and not opening any other programs or browsers, it just took about eight minutes to import 23 files, and a few more minutes to build 1:1 previews.  When things are running fine this might take one minute.  (I always build 1:1 previews on import and this happens with recently imported files as well as older ones, so it's not a question of having to build previews on the fly.)  I've had extremely slow performance ("Loading") just moving from one photo to another in the Library and Develop modules or moving from one module to another, typically up to about 90 seconds, or when LR is "preparing the file" for export or edit in PS.  But not always -- sometimes it's quite zippy -- and there's no pattern that I can see.  Generally when this is occurring, memory "pressure" and CPU usage are normal, but it happens when usage is minimal as well.  Occasionally there is a spinning beach ball but not usually. 
    My catalog has about 30k photos and very few presets of any kind.  Probably 75% of these files have never been edited at all.  I don't make hundreds of local adjustment, rarely more than ten in one image.  I have about 40 Smart Collections with an average of several hundred images each.  I rarely use Smart Previews.  I optimize and back up the catalog every time I exit LR, which is a few times a week.  My file/folder structure is simple and clean:  /Pictures/year/day.
    I'm running LR 5.4 on a mid-2011 iMac, 3.4 GHz Intel Core i7, with 16GB of memory.  I have the Lightroom catalog and previews on the main drive, which is a 250GB SSD with about 100GB free.  (Problem happened when my catalog was on different internal drive, too.)  My pictures folder is on an internal drive with over 100GB available.  I have the maximum cache size set to 50GB.  I'm running Mavericks but it was just as slow under Mountain Lion.  It was just as slow in earlier versions of Lightroom, major and minor.  Other programs/apps run just fine on my computer, including Photoshop.  (Generally, LR's performance is the same whether or not PS is running.)  The only performance issue I've noticed since switching to Mavericks is that Finder stalls for several seconds every once in a while.
    I've seen this Lightroom problem referred to on various forums, including Adobe forums, for a long time now -- years -- and I've never seen a definitive fix.  I think I've answered all of the questions that are usually asked.  Is there any solution to this?  I use LR 30-40 hours per week.  I'm tearing my hair out and the option of moving to another program would be the very last resort, but I might have to do that. 

    I don't use your same workflow, and I assume you're shooting RAW. However,  after I have built 1:1 previews in LR (which takes a LONG time), when I click on a file to decide if it's sharp or not, it still takes 5-10 seconds for each file to load. And my computer isn't slow, and I have the same issue on my laptop, which is new and fast. I haven't seen a satisfactory answer to this problem, nor much acknowledgement from Adobe. My files are from a Nikon D7100 with 24 megapixels, so the file size is likely a factor.
    If you are shooting the type of subjects where you use 1:1 previews primarily to determine sharpness, you could consider Photo Mechanic (unfortunately it costs $150) as the first step in your workflow. It uses the embedded jpg files in the RAW file, so it loads 1:1 jpg previews almost instantly. Sports and nature photographers use this product all the time, mostly to delete losers.

  • Very slow performance running Mavericks - need troubleshooting help

    Hello folks:
    I have a MBP 2011 which was upgraded to Mavericks from Mountain Lion about 6 weeks ago. Since then I have had a major performance drop - slow machine, very slow window renderings, etc. I know a number of people have been facing these issues and have been recommended to clean up 3rd party extensions/agents. I ran Etrecheck (report below) and I need some help with fixing the failed kernel extensions and launch daemons. Thanks much!

      Western Digital My Book 1148 3 TB    WD drives are one of the worst things that can happen to a mac. They have software on the drive and also in the firmware of the drive enclosure that is incompatible with Mavericks. The software that they also want you to install on your mac (to run the drive with the shitware on it that is incompatible with Mavericks) is also incompatible with Mavericks. The best thing to do with this drive is to open it and remove the hard drive and put it into a new (non-WD) enclosure. Then smash the WD enclosure into little bits with a sledgehammer and mail it back to WD.

If the driver is still there after that, I'd look for the extension in /System/Library/Extensions and delete it from there. This may have damaged your kernel, though. If your performance is not improved after removing the WD app and this extension, you should probably back up your documents, erase your HD, and do a clean reinstall of Mavericks.

Repair permissions too while you're there. OS X: About OS X Recovery . Then restart, reassess your mac’s performance, and rerun Etrecheck. If that doesn’t work, I’d reinstall Mavericks over your current installation. If that doesn’t work, I’d do a clean install.

  • Very slow performance / format

    How can i formate ???
    OS taking so much time to set when started...
    Slow performance very slow
    Any solution?

    See your performance is slow because the app you are using doesnt get enough memory or CPU. SO try to minimize the load off so that the requistite power goes to the app which you are tending to use. One such method is to open task manager. Then startup. Disable the app which you dont want to. Like I have disabled them. This would definitely power up your system. Try removing unwanted apps from your PC.

  • New VM Server - Very Slow Performance with QuickBooks

    Hello all,
    Oh the dreaded performance issues!
    Okay we currently have a virtual server hosted with a different company - it has two VPU's and 8GB RAM.  The contract is about to expire so we're switching to a Microsoft Azure VM.  This server is running Windows Server 2008 R2 - main purpose is
    to host QuickBooks Enterprise v15 - with 10 users connecting via RemoteApp and/or RD.
    So for the new Azure server we selected the A3 (4 cores/7GB RAM) option - running Windows Server 2008 R2 - I know old O/S - but still need for now.  We also attached a new 250GB disk for additional storage of data/programs.  The test users noticed
    performance issues right away so we temporarily upgraded it to the A4 option (8 cores/14GB RAM) and although it is better there are still performance issues.  For example to run a statement report in QuickBooks - viewing both connections side-by-side
    - it is 2x faster on the current "live" server we have hosted with the current hosting provider.  On the Azure VM we also tested installing QuickBooks on the C:\ drive and then on the attached 250GB disk - the F:\ drive - same performance results
    on both.  
    This is a new VM...fresh install....just so strange why it would be slower than the 8GB server.
    Does anyone have any ideas on where we can start to troubleshoot this?  
    Thanks so much!

    I understand the performance seen by end users are low. However, do you know what is really wrong? Do you see Azure VM using almost 80% of CPU & RAM, if not adding more RAM & CPU may not really help you.
    - How is the CPU usage of your on-premise node vs Azure VM
    - How is the memory usage of your on-premise node vs Azure VM
    Do you have any specific characteristics for Disk IO requirement? Can you check IOPS on on-premise vs Azure?

  • Dell 1564 - Intel I5-M430 - Overheating issues, very slow performance

    Hi,
    I have a dell 1564, with an I5 M430 cpu. I have cooling issues and as a result my CPU temperature peaks close to 90~95 degree Celsius sometimes on extended full cpu usage. In such situations , I cut down my usage , and manage to bring the temperature down back to reasnoble ranges of 60~75 degrees. However often in these situations even after cooling down, my cpu performance becomes very miserable. Normal browsing which usually uses 10~15% cpu show up as taking 80~90% cpu (as per top/ and other process monitors). I ran the "N-Queens" benchmark from  hardinfo show drastically reduced performance. Post overheating the benchmark takes 35s, after a reboot it takes only 7seconds. I'm trying to track down the reason for this but can't seem to figure out what's the issue. Can someone help me out in this? I'm basically looking for a solution where I don't have to reboot every time I cross the temperature threshold just to get normal CPU performance again. Ideally if its downclocking somehow I'm hoping that it should reset back normally after temperature returns to normal ranges.
    Stuff I've tried:
    * dmesg : No new messages added during/after the overheating
    * cpu scaling : cpu frequency reported by /proc/cpuinfo are back to the normal 2.26 GHz which is my peak scaling. Also I've tried all scaling governors , and even locking the frequency to 2.26GHz , doesn't seem to bring back the performance.
    * suspending and resuming , in hopes of reseting any CPU modes. No luck, CPU still in bad performance. Only a reboot fixes it.

    Any suggestions , to either fix this , or ways to track down the issue, will be much appreciated. Will be happy to provide more details , logs, or specs if required. I'm right now totally clueless as to even how to figure out what's going wrong so anything is welcome.

    The one thing that sticks out is Firefox is using an excessive amount of CPU resources.  Delete Firefox and see if there is an improvement.
    Ciao.
