Application got slowed down

Hello every one 
 I have written a code in labviw and
 I am running an application in a pc with 4gb ram, i5 processor .
Problem is the application is running slowly in this pc  .
When i am running the application i when to task manager to see the pc status please see the attached pic 
When i go to another pc with 2gb ram it is too slow 
So my question is
1 how to increase the application speed ?
2 If i integrate the VGA card does the application speed increases ?

You don't provide enough information to troubleshoot the problem. CPU use can be high if you have polling UI loops without small waits. Memory use can be high if you have huge data structures and many data copies in memory (e.g. overuse of local variables or generally inefficient code).
Please define "slow". Do the computations take more time that you think they should or does the user interface feel sluggish? How do you measure the slowness?
What does the program do? Please show us some code!!
Typically, it does not help to simply throw more CPU power at the problem if the root cause is in inefficient and wasteful code. A faster CPU will simply waste even more clock cycles per unit time.

  • Application folder slowed down after 10.6.5 upgrade

    Hi,
    im not too sure whether this software upgrade cause the problem. my application folder slowed down when i am scrolling. it will lag and not as smooth as previously.
    any way to resolve this problem. hope to hear from you guys soon. thanks alot: )

    Are you referring to the list view in the Applications folder while open in Finder?
    Did you take the usual precautions before and repair permissions after the latest software update?
    If not, go to Disk Utility and repair permissions first. Restart.
    If problem persists, it could be a corrupt preference file; go to Users -> Library -> Preferences and trash this file: com.apple.Finder.plist. Restart and see if the issue is resolved.

  • How do I fix a Safari application that slows down and freezes everything?

    Apple called last fall and said my particular Mac had a hard disk problem and they replaced it at the Apple store in late January 2013.  I backed up the information on an external harddrive and used Time Machine before to transfer all the information to the new drive. Everything worked well and I finally put on Mountain Lion at 10.8.4.  I also have Carbonite as a backup and it apparently was not enabled when I transferred the files until early May.  In early May I had not used my iMac for about a month and when I started it I found about 40 named file folders on the Desktop that were empty.  Some of those had named items in them but when I clicked on them they would dissappear.  The actual files did exist and were not effected when I dumped the apparent alias folders. Safari started and would be ok at first but if I went away for an hour it would slow down.  I took it in to the Genius Bar at Apple and they ran some tests and got rid of MacKeeper which they felt was causing the problem.  I got my Mac back home and it still started slow but worked well at first and then started going slow.  If I opened Word it would also start working at a slower speed.  I needed to force quit Safari and the Word progran in order to quit or restart the Mac.  I got an appointment for the next day and they ran all sorts of tests and the hard drive was working normally. They tried tweeking different areas and sent me home again.  When I started working again it did the same thing, I would start out fine and eventually slow down and needed to be force quit to get out of it. A message came up indicating my MasOSX startup disk had no more space available for applications memory.  I took it in a third time and the Genius went to the Activity Monitor and the Safari PID was 221 and %CPU 107, Threads 21 Real Mem 2.73 GB, Virtual Mem 22.00 Kind, Intel (64).  I had no idea what that meant. I went home again and it still ran slow and couldn't run the programs for any length of time before it ran slow and affected the other programs so they would only quit if I used Force quit.  I took it in for the forth time an they decided to keep it overnight. They ran ASD first to rule out memory.  They noticed during the appointment the computer was slow to perform normal tasks such as showing boot options, booting into user, bootingto external user.  If the ASD passed then they would perform erase and install and only restore users and application files from backup drive.  They did this on Wed and Thur. night and I took it home Friday night, June 14 and it still has the same problem. Typing this message right now means typing and waiting for the words to appear.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Application Express slow down

    I launched my first APEX application a week ago - before I went on my vacation. At that time, the response time was extremely fast - no matter if the user was trying to navigate between pages and tabs and to log in or log out. When I came back this morning, I found that the application was slowed. Then, I tried to see if the slow performance was related to the shared memory by clicking the same record several times for several records. What I saw was that the first time I called the record it was slow. When I called the same record after the first time, it became fast - because the record was cached. This showed me that the problem might relate to the shared memory. However, since the database is very small and the total SGA is already 300MB (Shared Pool: 148MB,
    Buffer Cache: 136MB, Large Pool: 4MB, Java Pool: 4MB, Other: 8MB), it doesn't make sense to keep adding memory to it - especially the database server is now shared by 5 individual databases. I wonder if, after a while, some logs or sessions in APEX need to be "manually" purged in order to increase the performance.
    Thanks.

    The performance issue of APEX is strange because, at the very beginning, the performance of the application increased extremely right after I changed the total SGA from 198MB to 300MB (with about 160MB for buffer cache) - every page or tab was immediately loaded when clicked. It lasted for about 2 weeks. Then, since last couple of days, it slowed down significantly. It was no use even after I again increased the total SGA from 300MB to 400MB and re-started the database. This doesn't make sense because the performance should be consistent. Also, it is a very small database with only 5 users.
    Has anyone encountered the same issue?
    Thanks.

  • Application launches slowing down

    Greetings All,
    Please forgive as I am not as computer literate as most on here. My questions is as follows, I am on a G-4 purchased in August of 2000. All my software is up to date. Recently, I have noticed that it takes longer and longer for Safari and Yahoo IM to load. The icon bounces and bounces but eventually the programs open. UP until recently, both programs opened almost instantly. In addition, my Itunes takes longer to open but not to the same degree. Can anyone tell me why this is happening?

    Welcome to Apple Discussions
    Wondering how much available HD space is on your computer? If you go to the desktop and single click on the HD icon, then Apple Key + I, the info panel will appear telling you how much available space is left on the drive. You ought to have around 10 percent free space for OS X to function properly. If it's less than 10 percent, you are in the red zone, i.e. you may have HD issues unless you clear some space.
    If space is adequate, it might help to perform some routine maintenance on your machine. For routine maintenance I use OnyX. There is no charge for the software, but I believe the developer asks for a donation.
    It's very easy to use. I run it twice a month. Once it is installed, you would double click on the OnyX icon in your application folder (or drag an icon to your dock for quick access) to open the application. After entering your administrator password, you would select "automation". The panel looks like this:
    Select the same items I have checked, also check the System box in the "Clear Cache" section this one time, and then select "execute". The program takes about 5 to 10 minutes to run. Leave your computer alone, that is, don't use it for anything else until OnyX is finished. Once complete, restart the computer and you're good to go. On the restart the computer may take a little longer to start up because it is resetting the System Cache, Ordinarily, it's best to leave the System Cache alone, however, given your description of the "slowness", this might help too.

  • Flex or AIR application is slowed down after continuous usage.

    Hello,
    I am facing two issues one each in Flex application and AIR application.
    1. First in Flex application.
    I have developed an Flex application in Flex 4.0 and is being used by around 10 to 15 users simultaneously.
    Now the problem is that when all the users start use of the application in the morning, it is running perfectly. But after usage of 3 or 4 hours, or let's say after lunch its speed is gettling slow. And due to low speed, application behaves abnormally. For example, I am calling multiple php files one by one through http service in one of the screens. And those php calls are dependent on each other. So due to low speed step 2 php call is over before the step 1 php call. And due to that application can't set the screen as per its normal behaviout.
    And this problem stays even after user clears the browser cache.
    So I am assuming that even after clearing browser cache flash player is not removing all the cache or something is still there on the server which is causing slow speed of the application. Because when next day users come to office and use the application they don't face such issues. Such issues are coming only after continuous usage of it.
    So please help me in solving this issue ASAP. Because our client is getting angry over this issue.
    2. AIR Application issue
    I have developed an AIR application which is using socket connection to use different designer softwares like In Design, Illustrator etc.
    Now sometimes happens that due to low speed of machine or internet my socket connection didn't get time to connect to some design softwares. So I have put a code that checks if the connection is lost then it reconnects it. But this connection lost problem starts coming after heavy usage of the application.
    And the second problem is regarding drag and drop. When I do continuous drag and drop of images of around 70 to 80 images, I get memory over error from the machine stating that please close the application as there is no memory available now.
    So please suggest a solution for this ASAP as our client will need to do lots of drag and drop operations and lots of socket connection to design software during the day.
    Thanks & Regards,
    Jigar Oza

    Here is the screen shot of my AIR application.
    When I do continuous drag and drop operation the highlighted VO or object instances are increased. These instances are increased and my system memory is used because of that. So how can I remove the instances of those objects which are used repeatedly?

  • Application download slow down

    Downloading Free apps one at a time isn't an issue, but try 2 or more is a difficulty. My problem now is there are 3 apps are sitting there, partial downloaded, waiting, but it's not moving. I'd like to remove these apps, but tapping them doesn't make them respond. The icons are in grey. I've run restore, powercycle, anyone with a solution how to cancel & remove them. I'll stick to downloading one app at a time.

  • Mountain lion update slowed down my macbook pro

    hey guys,
    I just updated to mountain lion
    however, after the installation, my macbook pro has been noticably slow.
    slow booting, slow when operating installed programs, chrome/safari got slowed down as well.
    Also it freezes for couple of seconds and i was wondering why.
    If any of u r experiencing same problems or know how to fix it please kindly let me know!
    Thank you!

    Have tried everything possible, repairing permissions etc to no avail.
    You haven't tried everything possible or you would have a solution.  If you tried the most extreme possible solution (erasing the hard drive, then reinstalling the system and nothing else) and still had the same problems, you would have discovered that you almost certainly have a hardware problem.  For some solutions that you haven't tried yet, I'll refer you to the same two links I referred sylee48 to.
    As for that article, that's an extremely unprofessional piece of writing.  They publish - as if they were fact - the conclusions of untrained, non-technical users who do not have the necessary expertise to make such conclusions.  And they concluded that these were bugs that Apple should be working on.
    In fact, this may be one of the smoothest upgrades I've seen in a while.  (Boy-oh-boy, you should have seen the screaming here for the Snow Leopard and Lion upgrades!  It's positively peaceful in this forum compared to that.)

  • Why do GarageBand, iMovie, Photobooth, and Hulu and Youtube videos slow down my whole computer?

    I have a higher end 13" MacBook Pro running OSX Snow Leopard 10.6.8 that I purchased in August of 2010. About a month ago, I was using iMovie to edit a project when all of a sudden it started responding extremely slowly. Like, near impossible to work on my project slow. The whole computer was lagging, the mouse was unresponsive and I could barely use the gestures on the trackpad to get to different programs. Eventually the pinwheel of death showed up, and I quit iMovie. As soon as it closed, everything returned to normal. I restarted the computer to see if that would help, but as soon as I opened iMovie again, the whole computer started lagging. I then noticed that the same problem occured when I used GarageBand, iPhoto, Skype, and when I watched Hulu or YouTube videos. With all of these programs/sites, everything is running fine beforehand, but when I open them up, chaos sets in. This problem doesn't occur when I use other intensive programs like Photoshop or Illustrator, nor while I'm browsing the web. The only web problems are when I watch a video. Any video. Other than that, web pages are as quick to load as ever, and I can use the computer normally for any other task. This is seriously a problem because I use iMovie and GarageBand for school a lot, and my grades depend on me being able to use these programs effectively. All of these problems have persisted with these apps since that first instance about a month ago, and no significant changes occurred to instigate them. In attempts to solve the situation, I have cleared my cache, freed up space on my drive (I have 56 free gigs out of 320), I have verified and repaired the disk permissions, and I have downloaded the Apple provided Trojan removal tool for Snow Leopard. This seemed to work for about 10 minutes, but the apps and videos quickly started lagging and slowing down my whole computer again. If anyone else has experienced anything like this, I would love to hear exactly what has happened to you and to see what you did to [try to] fix it. Thanks for reading all of this, I need all the help I can get right now. Also, I can't watch The Daily Show or The Colbert Report on Hulu anymore, and it's killing me! Thanks again.

    It's very difficult to say without knowing more about your system. There are a number of possibilities. First, your 13" lacks a discrete GPU, so the CPU is doing the work that a GPU would have done as far as decoding video streams, etc. Each video stream will consume considerable resources from the machine, and if you have multiple things running with video streams being decoded (for example, a browser with video Flash or cumbersome animation and iMovie running at the same time), then that may be a factor.
    Additionally, it could be that you are memory constrained. You didn't post a picture of the process list from activity monitor or the memory usage stats, but you probably want to look and see what the memory and CPU usage is and who's consuming what. Some applications are pretty inefficient. For example, if you have iPhoto open and have thousands of images, the indexed metadata and thumbnails are all stored in RAM. iMovie pulls in clip thumbnail sets - (and worse, it has to do on-the-fly transcoding video assets from some cameras that don't encode the video using the parameters it expects to make indexing frames easier). Again, this would show up as periodic spikes in CPU activity for the app.
    You seem to have plenty of disk space, that's not likely to be a problem.
    Check if Time Machine is running. Time Machine introduces a performance impact, but it's exacerbated by the presence of frequently changed large files (e.g., you don't want Time Machine backing up your video projects while you are working on them).
    Lastly, you may consider checking the console for error messages. This might reveal background processes that might be bogging down the system, or things like filesystem/disk errors. If there are errors in the filesystem, when you access certain portions of the disk, the OS and applications can slow down or lock-up as a result.

  • Iphone 4s/IOS8.1 slowed down my phone

    Hi,
    ever since downloading IOS 8.1 on my iPhone 4s all applications have slowed down.  Another problem is that Siri now only works maybe 50% of the time telling "I'm really sorry about this but........
    Appreciate any help.
    Thanks, Scott

    Well, iOS 8 has been designed for more graphically faster phones than iPhone 4S. However, you can always downgrade to iOS 7, but Apple doesn't support it. You can of course go for an upgrade. It would be worth an upgrade from iPhone 4S. Good luck!

  • Computer slows down and locks up after installing Xtreme Mu

    I recently upgraded my Audigy 2 to the new Xtreme Music soundcard. The music sounds great!? Before install, I uninstalled all drivers from the Audigy 2. Now, my computer behaves differently. Before the login screen (Windows XP), my video flashes multiple colors for about 2 seconds. After logging into Windows, applications have slowed down (this is after installing the drivers for the sound card and updating the software to the latest from the website). For example, Email took some time to come up (outlook), and then a word attachment refused to come up. IE took considerable amount of time to launch. This is after running the computer with the sound card for a week.
    The problems aren't consistent. I returned the card, and the salesman asked if I plugged in the external power (floppy dri've connector). I read the instructions, and they did not state to do this, but I will give it a try. I swapped the card for a brand new one and brought it home. This time, I plugged in the external power. Same symptoms, if not worse. It is sporadic, and sometimes worse than others.
    This morning, my computer was working extremely slow opening IE or Outlook and reading email. I pulled the sound card and all is great again. Bummer!? I really like the sound this card produces. My fear is, will ANY X-Fi card do this or just the Xtreme Music?I have an ASUS P4P800 Deluxe (onboard sound has always been disabled). I didn't have any problems with the Audigy 2. 550W power supply, Gig memory, Pentium 4 2.8 GHz processor, and and ATI X600 video card. No other cards are installed in the system.

    I tried it is 2 separate slots. Same symptoms. I am looking to see if it is a power issue (not enough juice from a 550w power supply), or if there is a conflict. I still have the creative drivers and software loaded without the soundcard installed and no problems (So I'm ruling out the creative sound software).

  • Parallel processing using NSOperation slows down application!

    For the "fun" of it, I'm creating a little application which matches images in iPhoto to my GPS logs (in GPX format) to geocode the photos.
    Currently, I've got it to the point where it will go through my images (about 1000, but only around 250 with matching GPS data) and gets the right data from the GPX files.
    The process was taking around 9 minutes to do, but with some alterations (using caching to eliminate GPX files outside the relevant date range) I've got it down to 3 minutes. The problem is that when I use multiple cores (Mac Pro 2x QX) it actually slows the process down to 3.5 minutes.
    All the processors are running with 50% load (were running at 100% before my other alterations that improved performance), but analysis shows 95% of the time being spent waiting in the XQuery routines.
    I imagined that this application would be perfect for multiple processors, as the matching section was processor intensive (complex XQuery expression) and appeared to be a very independent process.
    The shared resources passed to the function are:
    1) the path to the image being processed
    2) an array of GPX files (subclass of NSXMLDocument)
    Additionally, during the function it updates a dictionary related to the image (adds in the location data found).
    I've tried to eliminate the block by sending a copy of the GPX array in case the system is locking access to the array (although it is not mutable) while it is being enumerated (using Obj-C 2.0 enumeration).
    Can anybody give me a hint what would be causing these supposedly independent processes to be waiting? My only guess is that the XQuery library isn't thread safe, but can't find confirmation.
    Memory usage is being kept low, and there aren't any page swaps showing up.
    Thanks.
    Ray.

    But there is only a single disk where all these images reside. But then, you said there was no disk activity. How are you accessing these images?
    I was a little inaccurate with my earlier posts. The images I speak of are at this stage is just the iPhoto albumdata.xml file, from which I obtain the date information for the image.
    The iPhoto file is read into memory and decomposed into the array of image data, from which the date is obtained and passed through to the xQuery methods.
    Perhaps not processor intensive (in terms of performing calculations) but reading from memory and comparing.
    Read from memory into where? Either it is on disk and you have serial access only or it has already been read into RAM.
    The GPX files are read into memory (i.e. RAM) when the programme launches, and converted into NSXMLDocuments. So there will be lots of memory access, but not disk access.
    As mentioned earlier, I've duplicated the array containing the files… (+realisation happening+)…
    Perhaps it is access to the NSXMLDocument files that is causing the lock. I've duplicated the array, but not a deep copy down to the actual XML objects. I'll see if that makes a difference.
    You shouldn't have to do even that. If you are just querying, there is no modification needed. They can all share the same data.
    That's what I figured too, especially since it is not a mutable array. I didn't have any luck with deep copying as my first attempt caused the programme to run out of available memory.
    But in reply to your question, when running as a single thread the bottleneck is also the XQuery execution. It takes about 1 second to execute a query on each relevant GPX file for a match. About 10 seconds when done in parallel! :-o
    How big are those files? How many GPX files do you have.
    Will have around 100 when it's running properly, but at the moment I'm using about a dozen. Each file is around 1MB.
    I would think you could merge all the data from all the GPX files first. Then start one thread to go through all the image files and pull out the search values and put them into a queue. Then have all the cores create an operator and grab a data element from the queue to process.
    My initial thought was to simplify things by merging them all, but the issue with that is the computer would need to scan one huge file for each image, rather than being able to omit the individual files that fall out of the date range relevant.
    Or, you could swap the problem space axes. You could divvy up the GPX data between all the cores. Then, for each image, look for a match in each subset - there should be only one. If NSXMLDocument is the bottleneck, this would solve it.
    May not be effective as it's only the relevant GPX file that takes a long time. The rest of the files are checked against to see if they cover the date in question, and skipped if not. Images without GPX data for their date (most of them since I'm using a test set of GPX files) get processed in the blink of an eye.
    But I appreciate the effort you're putting in to come up with possible solutions.
    While I'd like to know the reasons it's not working, I've got it to the point where it's processing images (with matching GPX files) in less than half a second on single thread, and putting the whole matching routine in separate thread has given me UI responsiveness. So if gets no better, at least the user (i.e. me) is kept entertained by the feedback while it runs.

  • Where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable.

    where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable. Thank you.

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
    3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
    Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction.  Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
    6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

  • Portal slowing down after import of application (New bug in 3.0.8 ??!!!!)

    We have two complete IAS installation (Portal 3.0.8+DB 8.1.7.0 EE) based on NT4.0. One is development, second production. Before moving application, clean prod machine is running forms very fast (least than 1 sec to show complete form). After importing application into the same schema (moved exp/imp db utility), performance is slowing down 1000%. The same form appear in 3~4 minutes.
    What's wrong with my portal.
    Does anybody move successfully from dev to prod on NT environment?
    I'll appreciate for any comments.
    Marcin

    Regarding the performance issue..
    There is a workaround provided at: Thanks for this - helped 100%
    Marcin
    PS.
    Now I complete give up. We bought IAS1.0.2, which appear rather like beta version (more 20 registered bugs found just by us). Than oracle support concern that ver. 3.0.8 of Portal will be cure for any previous bugs. Then I lost two weeks of my work trying to install new version and fighting with low performance.
    Small piece of history:
    Portal 3.0.8 for NT was available since 12 april 2001.
    31 may 2001. Now Oracle is saying that 3.0.9 will be bug free. Maybe you should sit down for a while and develop some ver 3.x.x.x test and after you don't find anything release it.
    Don't test your software on the customers.
    We bought sw, get the knowledge and want to start our project. But how we couldn't do it on platform which is changing every three weeks?!!!!!!
    It's smells like Microsoft.
    NT4.0, srvpack1, srvpack2 (dangerous),srvpack3 forget,srvpack4, srvpack5 - Y2K, . . ... .. .
