How to understand debug parameter profile?

I don't know how to use the Profiler, but I was wondering how would these settings tell whether or not my application works well.

For example, we can choose 'number of created objects' option, and then after update I see that my application then creates objects 691... How could I say, 691 means reasonable or not.

Another parameter have the same problem, I hope to have a standard to measure whether this setting is reasonable or not...

Any idea? Thank you guys.

There is no standard of reasonableness for that sort of thing.  You must take account of your expectations, the long-term trend for, the time period in question and so on.

For example, if you create and don't do not free 691 seconds additional objects, then it is quite likely to have an impact on the treatment of BlackBerry.  If this has happened in a method call and you call this method 200 times before displaying the result to the user, and then, I'd say it's likely to cause a problem.  If however, it is the start of your program where you cache a number of objects to be used later in the treatment, then 691 won't be a problem.

When you perform this type of analysis, my first priority is to look for leaks, in other words, I create objects that don't get released until something significant happens, like my request for termination.  In addition, I'll get large and repeated objects, for example I don't really need map of bits or I have a temporary string which I am recreating 400 times that I'm going around a loop.

I'm sure that others they are looking for other things.

  • How to understand the time VI?

    Hello

    I use LV 8.6, and I'm curious to know how to understand statistics 'VI time' under the 'profile Performance and memory window.

    I let one of my screws "continuous run" for about 5 seconds, but in the profile window, time of VI out 1.17 seconds, while the SubVIs time is 0. If I understand well of the Help window, 'VI time' represents the time spent executing the code of the VI, what happens for the other 4 seconds? It is confusing to me because I did similar tests on other screws (with no subVIs), and it seems the faster of the VI, more time to VI is.

    Thank you very much.

    The time you see reported is the total of all the slices of the CPU used by the code.

    If the VI took 1 msec to start upward, then did a waiting for 1 second and then outputs, you should expect the total duration of about 1-5 ms alothough the run time in total was much more than that.

    Hi Ali,

    Thanks for posting your query in Microsoft Community.

    I understand that you ask for more information about how to create or modify profiles and about the other settings to Pro Evolution Soccer (PES) in 2014. However, I have a few questions to identify the problem and provide you with better assistance.

    1. The game is successfully installed on the computer?
    2. Have you used a third-party software to install the game?
    3. What is the brand and model of the computer?

    I would like to inform you that, according to the current state on the Windows Compatibility Center, this game is not compatible with Windows 8. You can check this link for more information.

    However, if you have already installed somehow the game in Windows 8 and need help to configure the settings in the game, then I suggest you to refer to the KONAMI support for assistance.

  • How can I change my profile picture

    Dear all,

    The modern Skype with features of the touch screen looks completely different from the old Skype that we used with Win 7 and earlier versions. For example, in the old Skype, we could go to the Skype button and easily scroll through the options 'change profile photo '. In the new Skype, there is no functionality to do. (That is, as far as I know). If you click on 'My account', it takes you to the Skype Web site. In this way, you can go to "My profile" and then "Edit", but the change has not only any button next to your picture to allow you to change. In short, I don't know what to do.

    Help, please. Thank you very much in advance for your attention.

    Dr. Taher

    Hi all

    I write the method to change the profile picture for the benefit of those who are still waiting to find out how.

    Go to your homepage to Skype by clicking on the small round sticker in the upper right of the page. This will display a larger version of the image. Left click on this photo only once and the screen changes from a windows form that invites you with other photos you own. Choose how you want your new profile picture, and then left click on the button below, called "OPEN". The next screen will be your home screen Skype with the new image.

    Fact.

    It can handle up to 16 GB memory DDR3-1333 (2 x 8 GB modules).

    No way to add a touchscreen. I don't know how you changed Intel Radeon graphics card, unless you have installed a different motherboard. The original motherboard has two graphics chips, so if you install the right driver you can access the AMD Radeon HD M 7470.

    The processor could theoretically be upgraded to an i7, but these improvements are rarely economically justified because of the high cost of processors unique and time required for doing the upgrade. Somehow, I think less than 10% of the improvements that we are discussing on this Forum actually. You simpler and better (more efficient) upgrade is to install an SSD. You will think that you have an i7 and 16 GB of RAM.

  • How to customize the default profile Win7

    Hello

    I was hoping someone could help me; I'm trying to customize my Windows 7 default profile.  The way I used to do in the past with WinXP was to:

    1. Create a local user account that have no administrator rights
    2. With this local user logon and tweak the desktop and applications like I wanted
    3. Reboot and a map than the machines of local disk to another computer
    4. Make a copy of the original default profile and name it "Profile by default (Original)"
    5. Copy the contents of the local user profile account I logged in earlier and paste it into the default user profile

    It worked like a charm and all connected users subsequently received the twisted user profile that I created.  With Windows 7, I use a lot of permission issues (even if I am logged in as a domain administrator or a Local administrator).  Also, I have granted local administrator rights 'Owner' on the default profile and it is still impossible to copy.  Unfortunately, I do not have a specific error.

    Any help would be greatly appreciated that makes me crazy.  It's something that I used to be able to do so simply with XP.

    Thanks in advance,

  • How to pass the parameter to the script for interface/Package in ODI

    Hello

    Yesterday I asked a question how to pass a parameter to run the script interface or the procedure?

    I don't know if it's possible.

    Any clarification will help you.

    Kind regards

    Mahesh

    Mahesh, why not try this in your machine? This will give you more clarity and confidence.

    ODI has always check if there is any variable used inside an object regardless of the interface or procedure or package. So whenever you generate the script, you will be asked to select the boot parameters. She's. Whenever you use this scenario, make sure you that you add the variables in the additional variables section of the Properties tab.

    So answer is that it is possible.

    Bravo!
