How about the performance of AIR 2.6 in iOS/Android?

Does anyone test the performance improvement of AIR 2.6 in iOS/Android? Could you share the result? It's pretty good if you can release your testing code. It gives me a headache to update my AIR 2.5 in Flash CS5.

Today, I created the AIR 2.6 environment to package my swf with Flash CS5. It gave me a big surprise, the performance became worse. Oh my god, who can save me?

  • About the performance of using shared variables

    Hi
     My system has almost 200 I/O points,I want to the host communicates with PLC using OPC(I had create a OPC I/O Server).
    If I use shared variables bind to OPC data items, there must be almost 200 shared variables.
    And my puzzle is that what's the performance of using these shared variables,will they eat up memory and processor?
    Another question is that if an shared variable will be time-lapse(i.e.,if an OPC data item value change feedback to  program block with 0 delay or not),if so ,then how many millseconds it will delaies? 

    here is a paper about the performance of shared variables.

  • Best pratices for the customizing about the performance

    Hello,
    I would like to know the list of the best pratices for the customizing BPC NW 7.5 about the performance.
    Best regards
    Bastien

    Hi,
    There are few how to guides on SDN which will give you a basic idea on script logic. Apart from this, you can refer to the help guide on help. sap.com.
    The templates might also effect the performance. The number of EVDRE functions, the number of expansion dimensions, the number of members on which expansion takes place will effect the performance. A complex formatting in the template will also effect.
    Hope this helps.

  • About the performance of plumtree portal.

    Please let me ask a question about the performance of plumtree portal.The good reply is not obtained although I have asked the support center in Japan.I saw the log of ptspy.Delay had occurred in the following two points.
    1. Although it is a "<.static.> InetHost::Select(xxxx) is called on 0 write+xx read sockets." part, what processing is performed actually in the message by the plum tree by the processing of inethost.cpp in a WebDownloaderParallel.dll component?
    2. Although it is the part of "CreateFilterContext()-Created new context at address" by the message, is it the operation which is creating the context path for connection with the exterior in PTGWFilter.cpp in a Gateway component?
    Moreover, although delay of processing may occur in these parts, what factor can be considered?
    Thanks,

  • Is there any benchmarks about the performance of BI web Intelligence

    Need to know any benchmarks about the performance of business objects web intelligence report against number of records stored in a relational database

    There no as such benchmark. However you can verify the actual time take by report query when fired directly on DB and time taken by Report to execute. and if there is lots of difference, then those report would ideal for tuning.
    e.g. if MOnthwise revenue report takes 5 mins and the actual query takes only 1.5 mins when fired directly on DB. that means something wrong with universe/reports.
    I hope this help you to get started.
    Please share your exp. its interesting to know.

  • HT201301 how about the Chinese language doc. Able to use with the My Lyric Book program?

    how about the Chinese language doc. Able to use with the My Lyric Book program?

    I'm not sure where you see that the links I gave suggested that. The iPhoto link (quoted below) in step 4 suggests dragging the library to the new location. You can do that in Finder by dragging the library to the external disk in the Finder sidebar. If you don't have a sidebar in Finder, go to the Finder View menu and click Show Sidebar. If the external disk isn't visible in the sidebar, go to the Finder Preferences, click Sidebar at the top of the Preferences window, and put a checkmark in front of External disks in the Devices section.
    You can move your entire iPhoto library to a different computer, a hard disk, or another location on your computer.
    Important:    Before you move your iPhoto library, it’s a good idea to back it up to a DVD or external hard disk.
    Move your iPhoto library
    If you’ve created multiple photo libraries, be sure to move only the library currently displayed when iPhoto is open. To move a different library, you first need to switch to it.
    Quit iPhoto.
    In the Finder, choose your home folder (it’s usually named after you).
    Open the Pictures folder (in the home folder) to locate the iPhoto Library file.
    Drag the iPhoto Library file to a new location on your computer.
    Open iPhoto.
    In the window that appears, select the library you want, and then click Choose.

  • Apple send the iphone from Singapore, but i'm purchasing from malaysia apple online store, how about the warranty?

    I receive the parcel that apple sent today, but i found that Apple send the iphone from Singapore, but i'm purchasing from malaysia apple online store, How about the warranty? is that warranty available in malaysia?? or singapore ?

    Singapore is the AFE distribution centre for Apple , in the same way all online purchases from Apple in Europe ship from Ireland the European Distribution centre
    As Templeton has indicated the location you buy from is the only relevant information for warranty

  • How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.

    How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.
    I am planning to buy a high performance PC to run my Windows and Linux servers as vitrual machines for my testing purposes.
    Initially i planned to build my own computer with recommended configurations but considering space constaints and cooling factors i think Mac Pro can be a choice. But need some inputs if Mac pro (Intel Xeon E5, 12 GB RAM) is good for running virtual Machines.

    You could even run Windows natively and still run your VM servers.
    I have seen reports and such on MacRumors and elsewhere - run Windows natively as well as VMs (can also do testing and run Mavericks in a VM under Mavericks)
    The fast internal PCIe-SSD, plus 6 or 8 cores, and 32-64GB RAM. Of course for $5,000 for 8-core, some Thunderbolt storage and 32GB/64GB RAM you can buy some serious hardware.

  • Gnome-shell with nouveau - how is the performance

    I have an old 8400GS and find gnome-shell's performance under nouveau pretty bad.  Is it my card or the driver?  If you have a more powerful card, how is the performance?  I'm no gamer but is there a more powerful (none fan cooled) nvidia card that's better?

    Looks okay.... guess my 8400GS is just underpowered for this driver.  I ordered the 450 GTS so we'll see

  • How about the Graphic Performance?

    Hello all!
    May someone can help me to get that clarified ...
    I have a MacMini with Thunderbolt connection. Latley I started to use RC Flight simulator which challenges the video card of my MacMini pretty much.
    How about a Thunderbolt Display? Will TB just "substitute" my current HDMI-Connection or will some computing power be "outsourced" to the display? In other words: will the graphic performance of my MacMini improve using a TB-Display or does it stay the same because the build in video card is still "in charge"?
    Thx for your help!

    No question the Thunderbolt is without doubt a fantastic display, however to answer your question I'm personally experiencing a performance drop (see my very recent thread in this forum).
    One of my reasons for finally getting the Thunderbolt Display was to enjoy some proper gaming on a big screen for 3D games both within OS X and Bootcamp. Even when I match my MacBook Pro 17" unibody's (early 2011) top resolution with the Thunderbolt Display for a like for like comparison, I get a performance drop which I was hoping would never happen. I was hoping that with the MacBook Pro in closed 'clamshell' and thus the MacBook Pro switching it's own display 'off' and presumably diverting all of the GPU's performance power straight to the Thunderbolt Display via it's direct fast Thunderbolt bus; that it would at the very very least match the performance when using the MacBook Pro's own display, but currently I have to choose the 'very low' graphics setting on some games to maintain a decent frame-rate for smooth game play.
    Mybe this is not a permanent Thunderbolt Display problem/fault and might be resolved at some point by means of a software, display driver or display/thunderbolt/GPU firmware update. If that be the case then I'll know there's hope at the end of the tunnel. Understandably I wasn't expecting my MacBook Pro 17" early 2011 to perform miracles with it's graphics performance anyhow, but it's 1GB Graphics adapter isn't all that bad either and is a half decent card that can give acceptable results. But If you where to match the resolution of the Thunderbolt Display to that of the MacBook Pro for comparison for yourself and then run a 3D game like say 'Dirt 2', you will soon realise there are slight performance issues; unless of course I'm doing something wrong.
    Here's hoping this may only be a temporary drawback for the Thunderbolt Display with 3D applications/gaming.

  • How is the performance for HashMap.get()

    hi all
    i just want to ask you guys how quick the hashmap.get() runs for a given key, if there are thousand of entries in the hashmap. thanks

    If you want to know how something is going to perform, write a tiny program and test it. Either put it on a profiler, or just put time markers around a big loop. Here's something that somebody (UJ, I think) came up with recently for comparing casting vs. toString after extracting from a Map. It should be easy to adapt to just the Map.get() timing. In fact, I think I added a chunk to do just that, as a control. Knock yourself out. import java.util.*;
    public class MapTiming {
        Random rnd = new Random(13L);
        public static void main(String[] args) {
            int numEntries = Integer.parseInt(args[0]);
            Integer key = Integer.valueOf(args[1]);
            new MapTiming().zillion2(numEntries, key);
        void zillion2(int numEntries, Integer key) {
            HashMap map = new HashMap();
            int ix;
            for (ix = 0; ix < numEntries; ix++) {
                int entry = rnd.nextInt();
                map.put(new Integer(entry), String.valueOf(ix));
            map.put(key, String.valueOf(ix));
            final int LOOPS = 10000000;
            final int TIMES = 5;
            long time;
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    String item = map.get(key).toString();
                System.out.println("toString= " + (System.currentTimeMillis()-time));
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    String item = (String)map.get(key);
                System.out.println("cast= " + (System.currentTimeMillis()-time));
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    Object obj = map.get(key);
                System.out.println("get= " + (System.currentTimeMillis()-time));
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    String item = map.get(key).toString();
                System.out.println("toString= " + (System.currentTimeMillis()-time));
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    String item = (String)map.get(key);
                System.out.println("cast= " + (System.currentTimeMillis()-time));
            for (int j=0; j<TIMES; j++) {
                time = System.currentTimeMillis();
                for (int i=0;i<LOOPS; i++) {
                    Object obj = map.get(key);
                System.out.println("get= " + (System.currentTimeMillis()-time));
    }

  • Nvidia 5200, how is the performance?

    Currently, I have a Radeon 9500 Pro video card, and no matter which driver I use (catalyst or open source), it freezes my computer dead.  In Ubuntu this really only happened when I did something with OpenGL (even glxgears) but since I've switched to Arch it has happened even while loading KDE.  Right now, I don't even have a xorg.conf file because that's the only way I can get my computer to load a GUI (I'm guessing that it is defaulting to using vesa drivers?)
    The point is that my friend is bringing me an Nvidia 5200 video card and I'm going to use that, but I'm wondering how the performance is.  I'm pretty sure it's gonna render things faster than my vesa'd 9500 Pro, but I know that my video card is actually much faster if I could ever have gotten it to work properly.  Does the 5200 support compositing, for example, without being slow?  Is having a slow video card going to hurt me in someway (I do OpenGL programming, but only small things).  Also, my current card is hooked up to my LCD via DVI, but the 5200 only has VGA outputs; how much of a degrade in quality will I see on my LCD?
    Thanks for the help.

    Alot of people on the forums seem to be having trouble with ATI cards recently so I'm glad I bought an nvidia card to replace an old ATI Rage card awhile ago.  Apparently nvidia and linux are a tad more friendly with each other.  I certainly had no problems setting up my card.  The 5200 is a little older than my 6200 and I'm not sure what effect the vga out is going to have but I'm sure you'll be happy with the nvidia card.
    After a recent nvidia driver upgrade I had to switch back to the nvidia-96xx driver for games to work properly so I'd say that you most likely will not be able to run the latest nvidia driver.
