Slow performance On certain webpages

When I view certain webpages, safari scrolls very slowy, as if it can't keep up. This happens specifically when I view the Apple Pro webpage. I notice this also in Itunes when I view the Itunes store. I'm assuming that Itunes uses the Safari engine so I figured it is probably related. The weird thing is it only seems to happen with Apple webpages. I can view these same pages in Firefox and Camino with no slowdown, as well as in any browser on a PC. Does anyone have any idea why this is? Thanks.

  • Slow performance of PreparedStatement

    I am having difficulty with extremely slow performance or a relatively simply Microsoft SQL Server 2000 call from my Java applet. Most of the application runs fine, but there are certain parts that are repeatedly giving me a long delay before completing their execution. The code is as follows:
    // Create the try block for the execution of the SQL code
            try{
                // Create the command to be executed
                String command = new String( "select Description, Enabled " );
                command += "from tLineInfo where( Line = ? )";
                // Create the SQL text to be executed
                PreparedStatement get = _connection.prepareStatement( command );
                get.setInt( 1, lineNo );
                // Execute the SQL command
                ResultSet lineInfo = get.executeQuery();
                // Display the information accordingly
                if( lineInfo.next() ){
                    // Populate the user data fields
                    description.setText( lineInfo.getString( "Description" ) );
                          <! more display code here >
    }   // End of if statment
                else{
                    // Clear the user data fields
                    description.setText( " " );
                           <! more display code here >
                }   // End of else statements
                // Close the result set in preparation for the next query
                lineInfo.close();
            }   // End of try block
            catch( Exception e ){
                // Display a dialog box informing the user of the problem
                Object[] options = { "     OK     " };
                JOptionPane.showOptionDialog( null, e.getMessage(),
                        "Error",
                        JOptionPane.OK_OPTION, JOptionPane.ERROR_MESSAGE,
                        null, options, options[ 0 ] ); 
            }   // End of Exception catch
            // Get the related area information
            populateAreaCombo( lineNo );       
    private void populateAreaCombo( int lineNo ){
            // Format the areaComboBox
             try{
                // Create a command to get the devices from the database
                String command = new String( "select Area, [Name], [Description] " );
                command += "from tAreas where( Line = ? )";
                // Create the SQL statement to grab the information, and
                // populate the search parameter
                PreparedStatement getAreas =
                        _connection.prepareStatement( command );
                getAreas.setInt( 1, lineNo );
                // Execute the command
                ResultSet areas = getAreas.executeQuery();
                // Loop through the result set, and add collect the areas
                Vector< String > controlAreas = new Vector();
                while( areas.next() ){
                    // Add the area to the comboBox
                    controlAreas.add( Integer.toString( areas.getInt( "Area" ) ) +
                            " - " + areas.getString( "Name" ) + ": " +
                            areas.getString( "Description" ) );
                }   // End of while loop
                      <! more display code here >
                    The application always seem to pause at the second PrepraredStatement call:
    PreparedStatement getAreas =
                        _connection.prepareStatement( command );This seems to be a very simple operation, and it is not even the execution of the query where the long delay is realized. Rather, it is in the actual creation of the object prior to the execution.
    The delay is very repeatable at this exact statement each time.
    Additionally, of interest, is that the delay is only realized on computers remotely connected to the database. If I run this code on the localhost, then there is no delay. As soon as I distribute it, then the delay is incurred. That being said, there is not a network related issue that I can identify here. I have even isolated the server to be on the network with just one other PC, and the delay still persisted.
    Does anyone have any ideas?
    Thanks

    I can determine where the delay occurs by adding
    dialog boxes at a bunch of different steps, then
    monitoring them for when they appear; a little
    archaic, of course, but an easy way to find this
    out.You should
    1. Get the start time
    2. Get the current time at each step.
    3. Print the results at the end.
    4. Repeat a number of times to average.
    >
    When you say that I should not mix database code with
    display code... What exactly do you mean? To be
    more precise in my description, I was simply setting
    a bunch of different text fields and/or check boxes,
    etc., based on the result set returned. It was not
    as if I was creating a portion of the GUI there or
    something. I am assuming that is an allowable
    practice...
    You should have a class that does nothing but the database work. That class should be used by other classes (like classes that do GUI.)
    I have made little effort to close my resources, and
    sometimes they are not closed at all. When you say
    "resources", what exactly do you mean by that? Are
    you referring to the result sets, for example? I do
    not know of other resources that need to be closed,
    except for the connection to the DB itself. This, I
    have as persistent throughout the duration of the
    user's session.
    You must close result sets, statements and connections. They must be closed in that order.
    I am not running this code on the Internet, but it
    has been designed to be run on a small corporate
    network ( < 10 users). This is why I opted for the
    applet to run the entire application through instead
    of doing more HTML work.That is ok.

  • My mac has slow performance when running two or more applications, ran onyx and cleaned cache but my macbook is still running slow. Recommendations?

    I've had my MacBook White running on Mac OSx 10 for about 2 years. My sister has the same type of MacBook and she isn't having any slow performance. I really don't want to install RAM and that can't be the end all be all of solutions. Please help!!

    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation.  TechTool Pro 4.5.1 or higher are Intel Mac compatible;  Drive Genius is similar to TechTool Pro in terms of the various repair services provided.  Versions 1.5.1 or later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.  These utilities have limited or no functionality with Snow Leopard and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
    I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.  Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Backuplist
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    iBackup
    JaBack
    Silver Keeper
    MimMac
    Retrospect
    Super Flexible File Synchronizer
    SuperDuper!
    Synchronize Pro! X
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup

  • Mac pro Slow Performance

    Hello Everyone,
    I made a similar post about this subject not to long ago but now im back in the same situation. I will just recap everything that i did and hear your guys thoughts on what i did.
    So to make a long story short.. I have a 2009 imac that contains all of my applications that i use on a daily basis. I then bought a 2012 12-core Mac Pro. Instead of being patient i wanted to start using this machine right away. I then set up migration assistant on both machines and literally copied everything over from my imac to my newly purchased mac pro. I later realized that this was a bad idea because it brought over boat loads of crap that was not being used (essentially 700GB) My computer was running very slow, defiantly not at speed of what a 12-core should be running at. so i started cleaning it up to the best that i could and was able to clear up 200 or so GB's. I still was not satisfied by the results i was getting. I kept getting beach balls and slow performance overall. so i went out and bought a 120GB SSD drive and figured that would be my best solution... well certainly it was at first. I then cleaned up my applications folder to clear up room in that folder. so after that was done i used migration assistant to transfer JUST the APPLICATIONS over to the SSD. After that was complete i then received a ton of crap on on the SSD. On boot up im not getting a pop up that is attached to a program i use to have on the iMac and is started to run slower than before the migration to the SSD...
    So basically this is where i stand. I am thinking about just starting over from scratch and only bring over the files and applications that i need on the SSD. What is the best way to take applications off of my imac and put them onto my mac pro (meaning without migration assistant) The reason i need to transfer them over is because i do not have all of the applications on CD form to just re-install again. However, if i need to get the applications from the CD's for this to work then i will just have tp go through with that extra bit of trouble to do it the right way.
    The whole purpose of this is trying to clean up my computer and keep it as organized as possible.
    If anyone has any recommendations for the best way to perform this operation, its greatly appreciated!
    thanks in advance!

    A clean install along with Setup Assistant (or Migration Assistant) really is good and important way to go.
    Too many issues moving to a newer OS and it has been made easy.
    You can CCC clone the home folders elsewhere.
    You can CCC the system and apps to another drifve and retain just your home library (the part that is now hidden which is annoying to some and taking too invasive into user space as if we can't and don't need access?)
    ~/Library
    The only apps you can are ones you may as well just download and mount and drag, the type that lack and don't need to install anything anywheres but the package of the app itself.

  • Mac book pro slow performance all of a sudden.. please help.

    Mac book is running slow all of sudden. Please help debug the issue.

    Back up your documents and everything else important to you, not that there is any reason to believe your hard disk may be failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
    To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
    Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
    When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Read about it here. It contains a link to download EtreCheck. Don't download it from anywhere else (such as may be found by following the results of an Internet search).
    Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
    It will take a moment to run as it collects its data.
    Copy and paste its output in a reply.
    Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
    EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
    After completing the above please determine if the problems also occur in "Safe Mode":
    Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    You must disable FileVault before you can start your Mac in Safe Mode.
    Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
    System performance problems for reasons that cannot be isolated to any other cause justify an  SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

  • Certain webpages not loading properly

    The last few days I have noticed that certain webpages are slow to load and then only a text outline appears.  When I open safari, the apple start page loads without graphics and only shows text on the left side of the page. 
    I am using OS X and Safari 6.0.5.  I have emptied the cache and reset safari with no luck.  I also made sure that "disable images" was not selected.  This is driving me crazy!  I should mention that some websites load with no problem.  Has anyone experienced this and found a fix?
    Thanks.

    Try troubleshooting extensions and third party plugins.
    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.

  • IPad air slow performance

    Hello there I bought a new iPad air 32 4g model and I have been noticing slow performance when opening a pictures of an app in the AppStore
    knowing that I didn't face this problem an iPad 2  also I have restore the iPad air and still the problem is there

    I had a 3rd Generation iPad on iOS 7.0.4. It's what I sold to buy the Air. It was terrible. I mean if the criteria you are using is efficiency and speed in moving around and using the OS, then it was terrible.
    Safari was sluggish in scrolling with basic pages, closing apps, opening new ones, the Music app would take 4 to 5 seconds to open with a small library of around 12 to 15 artists. Tapping on items would result in a delay leading you to thinking you missed it and hitting it again.
    I think the criteria you are using is "Did it work", then yes. Did it work well? Certainly not. It was a bit like Windows on an Intel Celeron CPU. it worked but drove most of us mad with how poor it performed.

  • Displaying Certain WebPages

    Hi
    I have just developed a problem with my homehub 1.5. I am having trouble viewing certain webpages over wi-fi on both my iphone and laptop. Pages which seem to have quite a lot of graphics/videos i.e youtbube will be very slow or just timeout. I don't seem able to view any videos at all. The strange thing is that some pages work very quickly with no problems. When I do a speed test (when it finally lets me on to the page) the speed seems ok, as is the signal strength.
    I have tried two different browsers on my laptop and two different iphones. All with the same problem
    I am also unable to download books over wi-fi with my kindle. Sometimes a HH restart will work with this.
    Does anyone have any ideas ?
    Thanks
    Michael

    You could try changing DNS servers on your computer, to see if it makes any difference.
    Normally your computer would ask the home hub to forward any DNS requests to the BT DNS servers.
    Its not possible to alter these on the home hub, however you can change the settings on your computer, so that it uses different DNS servers.
    It is fairly easy to change these settings, but it depends on whether you are using Windows XP or Windows 7.
    Its also quite easy to reset it again should there be no improvement.
    Both of the earlier home hubs do suffer from a problem with the IDS (Intruder Detector System) log file filling up, which seems to stop DNS functioning. There is so much "rubbish" coming in on the Internet, that this can fill up quite quickly.
    On an unlocked hub version 1, it is possible to turn this off, which fixes the problem.
    I would try changing the DNS servers on your computer first, so that instead of getting the DNS automatically, you provide the server addresses.
    A good start is to use the OpenDNS servers, which are
    208.67.222.222
    and
    208.67.220.220
    Leave the IP address and gateway settings the same.

  • CS5 or Pc  Slow performance?

    Hi there,I have a problem with my pc at work and because I am not quite sure in which one is exactly the problem I decide to ask you.The pc is intel pentium 4 with 3 Gb Ram  XP professional service pack 3 Photoshop CS 5.
    The pc is connected to server(data base).When I open a bunch of photos (20-30) approximately 8 - 12 MB each one and sometimes I experience a slow performance(for example I am trying to retouch/clone something and it takes a lot of time for the pc to redraw/respond) the interesting part is that it doesn't happen always(sometimes can be even 3 photos and it will take ages to do something) also I notice that after appr. 20 minutes it's suddenly start to work as it should normally(it's like there was an update and when is updated/complete everything is fine).When that start to happen today I restart CS5 and load the same photos and it work fine, so it is really bizarre for me.I put a 89% ram usage to the CS5(I pretty much use only all the time Photoshop and bridge )   also made the history steps to 7 and the cache to 6 for big and flat files.I was checking the Efficiency and it's all the time 100 % so it's like it's not the photoshop but like I said today i just restard the ps and upload the same photos and got fix...I tried to copy the photos on my hard drive(so it should not be affect of the performance of the server but still the same as when I take them straight from the server.Because the hard drive is only 80 gb ( I don't store anything there )   i did clean up and disk defragment still  the same situation.Do you know what can be the problem and is it the Photoshop or the Pc?I'll appreciate it.
    Thank you  

    Could be that your PC is sometimes looking to check things on the server, and maybe the server or network is busy/bogged down and you PC gets caught in that cycle mess.....so,
    suggest next time you use Ps, set win performance monitor perfmon.exe or perfmon.msc ; setup to view graph of disk use and network activity and cpu usage.....then you may see/track a problem area.
    on win7, task manager does most of the same stuff

  • Slow performance of discoverer portlets

    Hi,
    I am running into slow performance of a particular page in portal, there are multiple sites hosted on the portal but these all have static text and are very quick to load but the one page with discoverer portlets and a web-clippping portlet is taking ages. If I run these reports on their own they are instant. Has anyone had similar problems with 9.0.2 portal and the discoverer reports ? I tried to identify a particular report that may be the culprit by deleting them one by one and to no avail. After a few hours effort I found the design mode was hanging as well. Again, just for this 1 page.
    There are 3 tabs on this page with about 4 report portlets and 1 web-clipping portlet.
    Thanks for any help,
    Brandon

    Thanks for the help.
    Seems to have been resolved although I'm not sure if thats the end of the story. Will wait and see.....
    So far apparently a port conflict of some sort in the discoverer config was causing it to hang and then also other system demands on the network and server housing the discoverer end-user layer were also causing problems.
    No error messages unfortunately......

  • Slow Performance - Java Related?

    This is an old box that I bought used recently, but the system install is recent. The system performs very slowly - about 50% of the speed of comparable Mac's in the XBench database. If I use Xupport to manully run "All" of the system maintenance crons I get some improvement, but it quickly goes back to being slow.
    Looking at my logs I have a "boat load" of Java errors under CrashReporter; there will be a string of "JavaNativeCrash_pidXXX.log" entries - many of them, as follows:
    An unexpected exception has been detected in native code outside the VM.
    Unexpected Signal : Bus Error occurred at PC=0x908611EC
    Function=[Unknown.]
    Library=/usr/lib/libobjc.A.dylib
    NOTE: We are unable to locate the function name symbol for the error
    just occurred. Please refer to release documentation for possible
    reason and solutions.
    Many of the line entries that follow, but not all of them, refer to SargentD2OL, which is a Java app, which I installed, but it did not work properly so I removed it. Yet I continue to get Java errors that refer to this now non-existant app.
    I have read that Java apps use a lot of resources, and that D2OL in particular uses a lot of resources. Can my slow performance problem be Java related? If so, any idea of how I can fix this problem?
    G4 AGP Graphics   Mac OS X (10.3.9)   500 MHz, 512M RAM

    Sorry to take so long to respond, but other issues in life have demanded my attention.
    None of the solutions given have had any affect. My Java folder has both a 1.3.1 and a 1.4.2 app - the Java Update 2 will not reinstall because it sees an up-to-date app in the folder. But reading the update file it says the older Java will be removed - but it is still there. Problem?
    On XBench the system scores a 9 to 10, while similar boxes on the XBench database score around 18 to 20. My cpu, memory, and video scores are very low. The HD through-put scores are the only ones that are normal. TechTool Pro 4 finds no problems. I have removed the memory sticks one at a time and retested after each cycle - no difference.
    I have two drives, each with a 10.3.9 install. One works fine, scores around a 17 on XBench, the other scores a 9 to 10. So it appears to be a software problem. The slower install is a drive from a iMac G3 that has been moved to the G4 - are there issues with this?
    My favored drive is the prior G3 one (newer and faster than the other drive that system tests faster in XBench) - it has my profile and all my info on it. It worked fine in the G3 - no problems.
    Thanks for the help,

  • Slow performance on a iMac 27" (maybe originated by the HDD)

    Hello,
    Well, I've had my iMac for 10 months now, but have never really paid attention to its performance since it was my first Mac and I was upgrading from a quite old computer, so it obviously proved to be a far superior machine.
    However, I noticed the problem when I started to be more critical with my machine's performance (this triggered by the fact that I bought, some months after, a MacBook Air which flies beyond time and space). Curious about this, I requested a friend to do a benchmark test with Xbench resulting in his machine (another iMac 27” with comparable specs) clearly outperforming mine. Even the Air, with its slower processor and smaller RAM, has a relatively close performance.
    Additionally, I have started to notice how the computer takes a long time to start-up and, after the desktop is “layed out”, it takes a lot of time before the machine becomes “responsive” (I usually try to start Mail and Google Chrome as soon as the pointer pops in!) with the final result that I have to wait in company of the beach ball for quite some seconds (half a minute) and even after the application had started, I can still hear the HDD working it as if there would be no tomorrow! And then, it is slooooow. Funnily enough, “tougher” applications like Photoshop or Illustrator don’t seem to have as many problems, relatively speaking.
    A little bit on the background info: I have two partitions: one for Bootcamp (since I was migrating from Windows, I had some software that I wanted to use there: Matlab and Office, basically, and then some smaller Windows-only programs).
    Derived from the benchmark test, I think I might have isolated the problem to the HDD (not sure though!).
    SO THE QUESTIONS ARE:
    1. How can I verify that the slow performance is due to the HDD being defective/badly configured/etc.?
    2. Has the Windows Bootcamp Partition any effect on my machine’s performance under MacOS? (I would assume not, but you never know!). I have more than 1.3 TB free space left
    3. What kind of corrective measures should I take?
    4. Any other type of advice will be warmly welcome: I will try to do some PRAM and SMC resets but I am not counting on it. I had also ran the disk utilities and there were no permission errors (not so sure what this means, but I’ve read that it is supposed to be good news.)
    5. Any extra info you might need, lemme know!
    Greetz,
    Víctor.
    PS: Sorry for the loooong post. I tried to be thorough!

    1. How can I verify that the slow performance is due to the HDD being defective/badly configured/etc.?
    Run Apple Hardware Test: http://support.apple.com/kb/HT1509
    2. Has the Windows Bootcamp Partition any effect on my machine’s performance under MacOS? (I would assume not, but you never know!). I have more than 1.3 TB free space left
    Probably not but 1.3TB of free space left on the total HD is not enough for OS X, OS X needs a minimum of 10-15% free space! If you mean 1.3TB of Windows space I'd recommend posting that question in the Boot Camp forum.
    3. What kind of corrective measures should I take?
    If the drive is failing per the AHT then it's covered by warranty and will need to be replaced. Remember back up!!!!!!!!!!
    4. Any other type of advice will be warmly welcome: I will try to do some PRAM and SMC resets but I am not counting on it. I had also ran the disk utilities and there were no permission errors (not so sure what this means, but I’ve read that it is supposed to be good news.)
    Can't hurt, make sure you read the instructions carefully and execute the tests exactly as they are described for Intel based iMacs.
    5. Any extra info you might need, lemme know!
    If you no longer have a need for Windows on your iMac I'd recommend removing that partition using Boot Camp Assistant. That may correct your problems.
    I would also recommend checking if System Preferences - Startup Disk and see if your internal HD is highlighted as the Startup Disk.
    In addition I would recommend checking your Login Items (System Preferences - Accounts - Login Items) and delete any applications you don't need launching at Login.
