Slow performance when many small images displaying

Hey!

I'm working on a Flex Mobile game. It uses a grid of 2D game and I try to display tiles in the cells. There are 3 different images are used: one for the walls, a floor and one for the character.

I view these images in the following way:

I have a band with an id (displayGroup), I then create an array of new Image() with the position that they should be placed in and the image that they should use.

Then I bang on the table and add the images individually as an element in the group.

In the code, it looks like this:

var temparray:Array = disp.drawMapGfx(map, hero)
for each (var img:Image in temparray) 
{
    displayGroup.addElement(img);
}

Now the problem appears when I move.

What I'm doing now is the following:

var numImages:int = displayGroup.numElements-1;

var temparray:Array = disp.drawMapGfx(map, hero)
for each (var img:Image in temparray) 
{
    displayGroup.addElement(img);
}


for(var i:int = numImages; i >= 1; i--)
{
    displayGroup.removeElementAt(i);
}

I first enter the total number of images in the group. Then I add the updated images that take the new position into account, and then I delete all obsolete images of the group. I'm going to 1 instead of 0, because the element 1 is a rect that creates the background color.

For the test, I was using "run as iPhone 3 GS. Each image is 50 x 30, which, in view of the user interface is equivalent to 11 x 17 images + 1 for the character. Therefore the display up to a maximum of 188 images.

Reference photo:

mobile_imageproblem.png

The problem is images sparkle as the old pictures disappear and new images appear. What can I do to have it redraw the screen more quickly, in order to avoid flickering?

It would be logical, rather than redraw every image, simply move the entire scene and just load / remove images if necessary, rather than reload images?

And a small second question: is it possible to share a mobile app in a single AIR file, so that I can be ready for office friends who don't have smartphones help test it on their computer?

What is the world altogether?

Theoretically, you can load all over the world to start and use a mask to show only the relevant part of the world. With each movement of the character, move the mask to the next section.

  • Why firefox has slow response when I save images on hard drive?

    I have windows 7 64 bit and Mozila firefox worm 17.0.1. I have the following problem. When I try to save an image from a site (right mouse click and save as) the disk hard from my pc, firefox response is slow. It takes about 6 to 10 seconds. I thought that it was a matter of file size, but it turned out that it was not relevant because it was images of 10 KB to 500 KB. I did the following:
    -clear history
    -clear the firefox cache and the cache folder in my profile
    -Delete the downloads.sqlite and localstore.rdf files
    -J' changed the browser.download.manager.scanWhenDone and services.sync.prefs.sync.browser.download.manager.scanWhenDone false
    -clear the downloads window
    -Disable all add-ons

    After all this, the problem remains
    Then I started firefox in safe mode (help-> restart with the disabled... modules). The problem remains.
    Then I disabled the windows firewall and Microsoft security essentials (real-time protection). I don't have any other antivirus or firewall on my pc. Nothing happened.

    Then, I created a new profile (reset firefox). Nothing happened. A last attempt, then, remained to be done. Restart in safe mode. So I followed these steps.
    I ran msconfig and disabled Microsoft Security Client to start tab and Microsoft antimalware Service on the services tab. So, I did a boot in safe mode with network support and disabled windows firewall. Guess what. Nothing happened.

    I noticed that when I tried to record images, in the process, there was a significant activity of hard drive (the hard drive activity led indicator was constantly lighting) and firefox in the upper left corner, shown the message does not for about 6 to 10 seconds. You understand that saving a picture of 19 Ko in 10 seconds is not normal.

    Is - this problem has to do with the cache? The disc is a SSD (solid state drive). Do you think that it would be preferable to redirect the in-memory cache? (I have 6 GB of total RAM). This problem was also in previous versions of firefox, but I think that with this version, the problem is more common. This is not the case with all the photos, but it happens with more than 65% of the images.

    It also happens when loading a web page, but it could be a question of a heavy web page that uses a lot of resources in my system, while loading. The problem is the same. Constant hard disk activity and it takes time to load the web page. The problem with the loading of the web page, is not as common as with saving images.

    I think it's a question of management of the cache. What is your opinion?

    Thank you.

    The cause of my problem was the jump lists, which has Windows 7. There are two types of jump lists, automatic or custom. Automatic jump lists caused the slow decline in firefox via Windows Explorer. Finally, it was a windows problem exploring and not firefox. Windows 7 introduces many new features that cause slow system performance. In any case, the solution to the problem is to follow the steps:
    1. open my computer and on the address bar paste the path: %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
    2. press CTRL + a
    3. press SHIFT + DELETE and delete the entire folder
    I think the respective windows Explorer jump list is one that begins with 1b4dd67f29cb1962, in which case you do not want to delete the list of every jump in the folder. If you use firefox, download a file and then go to the above mentioned path and view the files by date. The most recent file must be the correspondent with firefox.

  • slow performance when two vswitches to connect

    I've recently updated to ESX 4.1i.  Now I see a performance issue with one of these virtual machines that I am running on it.

    The configuration looks like this:

    VM1 - & gt; vswitch1 - & gt; Device VM - & gt; vswitch2 - & gt; VM2

    On 3.5, I have the VM1 VM2 to scp without no performance problems.  Took about 20-30 seconds to transfer the file.

    But in 4.0 and 4.1, I touched the major performance issue.  It takes about 30 minutes to transfer the file.

    So miss me something that was added in 4.x or there is a problem in 4.x.

    Some additional information:

    I first used the native driver e1000, but when the 4.x problem is presented, I have configured to use the vmxnet driver.

    There are no other VMware tools on the device, only the vmxnet driver which I compiled myself.  vswitch1 and vswitc2 both are in promiscuous mode

    so that the briding work on the device of the virtual computer.

    Anyone have any ideas?

    -joubert

    Yes! I had this problem. It was my butt for a week. I felt like a fool until I finally found the root of the problem by reading the notes of 4.1 version. Search for them - but they speak of poor performance and disabling LRO to the core of your VM. I then googled to find out how to do this on my CentOS VM, which acted as a virtualized router and came on this page: http://nwsmith.blogspot.com/2010/07/patching-vmxnet-to-disable-lro.html

    I followed these instructions for my CentOS 5.5 VM and, well, my performance still smokes.

    See you soon!

  • Slow performance when you use the function

    Hi all

    I have a function that returns the name of the product based on a number of identifiers. I create a new table

    Insert into the product
    (
    Name
    )
    Select
    PRODUCT (PRODUCT_ID)
    OF x_table


    It works very well but there are approximately million rows in the table and preformance is incrediably slow. No idea how I could improce performace or if I have to do this another way?

    Thanks in advance


    CREATE OR REPLACE FUNCTION PRODUCT (P_PRODUCT_ID IN VARCHAR2)
    RETURN VARCHAR2
    AS
    L_Name VARCHAR2 (4000);
    BEGIN
    SELECT NAME
    IN l_name

    PRODUCTID = P_PRODUCT_ID3
    PRODUCTID = P_PRODUCT_ID4;

    It would probably be best...

  • iPad Pro 9.7 "slow performance on wifi

    Hi all - looking for Apple's brain trust land on this one.

    I recently bought the new Pro peripheral 9.7 "iPad (wifi and cellular) and have noticed a lot of slow performance when you use it on a wifi network.

    I also have an iPhone 6s so decided to compare the two head to head, both on the same wifi network. Going to the same sites, YouTube, download my diary, it's okay - 6 bulbs just with speed so that the iPad Pro chugs and takes significantly longer to download exactly the same content. The old iPad Air that I used to use never had this problem. The problem doesn't seem to be the same thing with WiFi cell, just the one. It connects to the wifi network is fast blisteringply so I exclude the network being the issue. I was wondering if anyone else has this problem.

    I must say im very disappointed iPad pro account $ 1300 or so I paid for it. I am strongly considering to return.

    Details: iPad Pro 9.7 "128 gb Wifi + 4 G Gold

    running iOS 9.3.1

    All advice appreciated.

    Mike

    Have you tried a hard reset of your iPad by pressing the sleep/wake and Home buttons simultaneously until your iPad goes to black and restarts with the Apple logo and then release the buttons?

  • When I resize a photo to the web LR displays a very small image, not the actual size.

    When I resize a photo to the web LR displays a very small image, not the actual size that appears when I download on a website! ???

    Yes, it should work. It should show you exactly what the image will look like on normal, non-retine displays. At least if you have the resolution of your screen (in preferences-> display system) the value 'best for display '. In this case your computer exactly double the resolution.

    The link I posted above is for when you want to go further. In fact, he shows how to send images of different sizes to people looking at your site on the retina against those who seek to your site on normal screens. This will allow a still sharper image that people can get on a display to display. What it basically does is make their web browser asks a 1600 pixel image if only they are viewing on a screen high resolution while asking a low-resolution image 800 pixels for people using normal poster. This example uses all available pixels to choose the type of display. It takes just a bit of HTML and javascript coding. My main site done automatically like smugmug has this built already, but my blog site does not automatically so I had to code around it. This makes your images look amazing on the screens with high resolution such as on the screens of the retina and iPads.

  • For many small files extremely slow copying speed

    Hello

    I am running Windows 7 64 bit on my i5 750 pc which, so far, has worked perfectly. However, I suddenly noticed this morning when I need to copy a folder that contains many small files (about 5,000) for a total of 115 MB on a USB it was copying EXTREMELY slowly. I'm talking only about 300 KB/s. The building is only a few months and I don't think I need to do a similar task before.

    Now before you think of questions arise on the USB, this has happened on two separate sticks either in ports at the front of my case or on the back of the motherboard (MSI P55 G65). This same USB that I copied eventually was able to copy to and from another computer around 20 MB per second.

    This anomaly has been forgotten until I tried to save a similar folder on my hard drive to another location on the same drive free. Void ~ 300KB / s. I've tested the copy of a series of large video files which are completed in a fraction of a second.

    The hard drive is a Western Digital Caviar Black 1 TB. The drive has about 800 GB of free and I ran the Windows Defragmenter but it had no effect on the copy speed. I tried searching on the net for an answer and found a person in the United Kingdom which had a similar problem copy to USB specifically and seemed to blame on the way its Windows Vista from copying small files and agreed to this. I don't think it's true but because my friend running Windows 7 64 was able to copy the exact same folder around its SATA hard drive and from my USB drive almost instantly.

    Windows 7 is fully updated and some drivers report that they don't work and there seems to be no conflict or anything of this nature, although I wouldn't say I've watched carefully, in part because I don't know what I would find. I run Kaspersky Internet Security 2010. Don't know if this is relevant, but when I built it first of all, my USB keyboard was not recognized (ultimate keyboard Das) in windows 7 (although work properly when installing curiously). This has been fixed by the update the motherboard BIOS. This is all information that comes to mind that I think may be relevant.

    Can anyone help please, it drives me crazy.

    Thanks - Tim.

    Thanks for the reply,

    I did as you said, and there is definitely an increase. I tried to disable it first, what things accelerated up to about 3 MB/s and when I left the program altogether, he jumped at about 20 MB/s, making it more than a second 5 copy for a little more than 100 MB. My friend computer above (of which mine is more powerful and better-specd) could do exactly the same operation in the same operating system in just a few seconds.
    I'll wait for Kaspersky to rectify the problem, but I still think 20 MB/s is terribly slow... In fact, slower than most USB flash drives and even less on the same hard disk. Anyone else has any advice / suggestions?
    Thanks again,
    -Tim.

    Have you already found a solution to this?  I see a very similar phenomenon when you copy a folder with more than 100 k small files into it (total data about 1 GB).  I can copy a 10 GB single file of SATA to SATA in less time than it takes to file copy of the 1 GB with 100 k files.  I have a box to open with the support of Microsoft, but they don't have anything for me yet.

    Thank you

  • Too many software - slow performance

    I too installed software and had slowed performance. Just added 2 GB of RAM, and it helped. Took the computer to Best Buy for analysis and they gave me a list of about 110 programs of software that are installed. However, when I go into Add/Remove Programs, controls, some of the software on the list of Best Buy isn't on my Add/Remove list. Where can I find the software that is not in the Add/Remove Control Panel programs, but is listed as the software on my computer? Can I assume that it will be in the Explorer of Windows Defender - software? Is there a 'General' rule which should absolutely stay and not be deleted? Will I guess that if there "Dell", "Embarq" (my ISP), "Microsoft", "Windows" - I should exercise caution and not delete?

    There are a lot of software listed below, but I hope someone can tell me to remove one or more of them.  Help! Can what software I remove to help my performance? Thank you!

  • When sending multiple images to photoshop camera raw, no images are displayed in photoshop.

    I send multiple images in camera raw to the bridge as part of my work. I make my changes and then select them all and click on the button "open the Images. When I did earlier using Photoshop CS6, all these images open in Photoshop CS6 and be aligned at the top of the window. Now that I have Photoshop CC, when I click on the button 'open image', I'm being transferred to the CC of Photoshop, but some images are open upward. Only a few hours after I downloaded Photoshop CC, Images have been sent there by Camera Raw, but they were sent one by one. I had to finish the job on a single photo, save it, then another of the images I sent Camera RAW would show up. Now, back to Photoshop after a break of 3 hours, I can not camera raw to send images Photoshop CC. I had to go back to my Photoshop CS6 in order to continue work on my assignment. I knew that there will be some changes in CC, but do not think they would be this boring.

    Also, in order to get several images displayed in Filmstrip mode in Camera Raw, apparently I have to send via Bridge. I can't drag and drop a folder into Photoshop CC. Is there a way around this?

    Hi terryleemartin,

    If please check, is your Photoshop and Bridge are updated to the latest version.

    In addition, reset the Photoshop preferences default back so if there is no change in the settings of this problem.

  • Very, very slow performance

    The performance of Lightroom on my computer became, at times, horribly slow.  My iMac is rebooted and do not open any other programs or browsers, it just took about eight minutes to import the 23 files and a few more minutes to build 1:1 previews.  When things work very well that it may take a minute.  (I always build 1:1 on import previews and it comes up with the recently imported as well as the older files, is not a matter of having to build previews on the fly).  I have had extremely slow performance ("Loading") just go from one photo to another in the library modules and develop or move from one module to another, usually up to about 90 seconds, or when LR "prepare the file" for export or edit in PS.  But not always - sometimes it is quite zippy - and there is no pattern that I can see.  Generally when this happens, 'pressure' of the memory and the processor are normal, but it happens when its use is minimal as well.  Sometimes, there is a ball rotation range, but are generally not.

    My catalog has about 30 k pictures and very few presets of any kind.  Probably 75% of these records were never published at all.  I do not hundreds of local equalization, rarely more than a decade in an image.  I have about 40 smart Collections with an average of several hundred images each.  I rarely use intelligent previews.  I optimize and save the catalog each time that I use LR, which is a few times a week.  My file/folder structure is simple and clean: / Pictures/year/day.

    I use LR 5.4 on an iMac mid-2011, 3.4 GHz Intel Core i7 with 16 GB of memory.  I have the Lightroom Catalog and previews on the primary drive, which is a 250 GB SSD with about 100 GB free.  (The problem happened when my catalog was the different internal disk, too).  My Pictures folder is on an internal hard drive with 100 GB available.  I have set to 50GB maximum cache size.  I'm running the Mavericks but it was just too slow under Mountain Lion.  It was just as slow in the previous Lightroom, major and minor versions.  Other programs/applications run fine on my computer, including Photoshop.  (Generally, LR performance is the same whether the PS is running.)  The only problem with performance, I noticed since switching to the Mavericks is Finder to hold for a few seconds each time than in quite awhile.

    I've seen this problem in Lightroom called on various forums, including the Adobe forums for some time - years - and I've never seen a definitive solution.  I think that I have answered all the questions that are commonly asked.  Is there a solution to this?  I use LR 30-40 hours per week.  I am pulling my hair and the ability to switch to another program would be the last resort, but I might have to do.

    I appreciate the suggestions.  I tried to use a new catalog with only a couple hundred pictures and the same thing happens.  I'm sure that my ssd is very good because Photoshop and many other applications use without delays.  However, so far I have never had these problems on my Macbook, which runs also Maverick, so I start to wonder if it is largely a problem with my iMac.

  • Extremely slow performance with Radeon HD 7870

    Hello

    I use a number of Adobe programs on my new 64 bit system of Windows 8, with 16 GB of ram, a processor Intel Core 2.67 ghz i5 and AMD Radeon HD 7870 2 gig. All programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bits, which is extremely slow performance with GPU to use enabled in my preferences (Photoshop selects by default). If I disable the graphic processor use, this slowdown faints. If I change the Basic Design Mode, there might be a slightly detectable improvement during Normal and advanced, but it is still horribly slow. The refresh rate seems to be only a few frames per second. Everything is slow: brushes, zoom, panoramic, as well.

    I tried changing the settings I've seen suggested elsewhere: I went 2 level of Cache, history says 10 and the size of the tile to 128 k. No effect. Photoshop is currently the default using 60 percent of available ram. Efficiency has remained 100% overall of all my tests. In addition, this slow performance touched me from the moment that I installed Photoshop; It didn't arise after previous good performance. The problem exists regardless of the size or the number of documents that I opened. Performance is always terrible, even when I create a new blank canvas of 500 x 500 pixels and try a simple task like drawing with a brush.

    Photoshop is perfectly up to date, and so are my graphic drivers (Catalyst version 13.1). Any help would be greatly appreciated; yet performance is so bad in Photoshop it is unusable, graphic acceleration activated. Thanks in advance for the answer.

    I use Catalyst 12.8 pilots at the moment and have a Windows 7 system and have a remote access utility called Radmin installed, but I don't know if seeing that Microsoft based Render driver is provided on Windows 8.  It seems that this could be the key, as the basic OpenGL implementation of Microsoft is made all in software.  If somehow driver Microsoft took control and you don't get really the GPU acceleration, then that would surely make things really slow.

    Rafaello, you have updated drivers...  You can post your top of your system information again?

    Have you tried a full, complete deletion ATI driver and reinstall from for example, 13.2 beta?  Here is the removal of ATI tool:
