Performance :: Improve Flex Performance For Invisible Views?
Mar 19, 2012We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
View 1 RepliesFlex :: How To Improve Performance Of App
Jan 19, 2010I am working on a flex application. The application occupies 100% of the browser screen, but it is slow to load. How should I improve the performance, what are the best techniques one should follow for improving the performance of a flex App. I did try some stuff though, I am not using relative layout instead i am using absolute layout and putting the buttons/images etc at exact places in a Canvas, still i feel it is slow. Can I profile the App or flex code to see where exactly the app is taking the maximum time to execute.

Flex :: Improve The Performance Of PurePDF?
Jan 31, 2011I am using the Open source PurePDF library in my Flex AIR application. The problem is performance:It takes 100% CPU usage and too long to generate a PDF.
I have done some analysis on it and find that the text writing in pdf is expensive. That's why I need to know how I can improve the performance. Are there any fonts for which pdf generation is less expensive, or is there some setting or tip that can make this process somewhat better in terms of performance? secondly in case of images the ImageElement generation is very expensive when writing that element to PDF. Is there any way to reduce the processing?
I found a way to reduce the ImageElement generation processing by resizing the image using flex and by then passing the small image's bitmap data to the image element. It works fine, and i have reduced the time of execution to a good extent. is there any way to tell PDF to work in chunks or divide the work in such a way that it may take more time to complete but won't block the GUI while the PDF is being generated?
ActionScript 3.0 :: Improve Performance By Using Multiple Air Apps?
Feb 17, 2012I have a program that is decently complicated in one area and the rest is simple. The complicated stuff is data crunching, pretty much. Would I get an increased performance by doing the data crunching in a second app and just having it send the couple bits of info I want from it to my other app that would be the front end of the program? Or is this a dumb idea? I know air doesn't by default multi thread, so I was just trying to think of a "work around."
View 1 RepliesActionScript 3 :: Improve Performance Using Blitting For Graphics?
Sep 9, 2010I am a bit new to using blitting for graphics. But I have worked up a few demos myself, and I have been reading a lot of information on the methods used. One common theme I have been seeing though is that all of them brute force rendering; drawing the farthest back object first and stepping through all other objects. even drawing objects that are going to be completely overlapped. The reason all of them say this is that any kind of testing to see what should be drawn actually takes more time than just drawing everything with no checks. Is there any kind of way to detect what should be drawn, that will run faster than just drawing everything?
View 1 RepliesFlash - Possible To Improve Performance Of Drawing Technique?
Oct 22, 2010Am currently working on a tool created by a colleague of mine and would like to improve performance. Basically, it's a tool for drawing on screen and uses a combination of Sprites and the Graphics class to draw a line segment every time the mouse is moved when the mouse button is down. Here is the drawing bit:
// on MouseMove
protected function drawLine(e:MouseEvent):void {
if (currentTool.thickness > 0){
//pen
var line:Sprite = new Sprite();
line.graphics.lineStyle(currentTool.thickness, currentColour);
[Code] .....
As you can see, it checks if the line 'thickness' property and draws if it is and erases if it isn't. I did think of using a technique similar to blotting here where it'd draw to a bitmap but I'm not sure this'd give the performance boost I want or if, indeed, there would be any way to have an eraser function. The drawing itself works nicely - this isn't the problem, it's the performance of the subsequent 'drawn' sprites.
Flex :: Improve The Performance Of The SQLite Database?
Apr 26, 2011Background: I am using SQLite database in my flex application. Size of the database is 4 MB and have 5 tables which are
table 1 have 2500 records
table 2 have 8700 records
table 3 have 3000 records
table 4 have 5000 records
table 5 have 2000 records.
Problem: Whenever I run a select query on any table, it takes around (approx 50 seconds) to fetch data from database tables. This has made the application quite slow and unresponsive while it fetches the data from the table.
How can i improve the performance of the SQLite database so that the time taken to fetch the data from the tables is reduced?
ActionScript 3.0 :: Improve Performance With Embedded FLVs
Aug 6, 2009I've been building a project that is essentially a mashup style editor. You pick from a series of clips, arrange them in order, and then can play them back. Originally it was a series of FLVs that would play one right after another, one stops, next one starts, but this wasn't seamless. So I switched to embedded FLVs inside of SWF files.
Locally this performed better, the videos were more seamless, no gaps where the video disappears because the FLV isn't ready to play, but online it brings the flash movie to a crawl. In total I have 56 video files, either FLV or SWF. There are 4 "tracks" that play simultaneously. Each track is made up of multiple clips. I'm preloading the videos so they are ready for playback when the time comes. The videos are alpha transparent.
ActionScript 3.0 :: Improve Real Time Graph Performance?
Mar 20, 2011I'm working on a simple real time graph. The data is polled every 50ms, and each poll translates to a line one pixel wide, (data_point) pixels high. The graph scrolls such that new data is on the right, and the oldest values eventually fall off the left.
My solution is embarassingly brute-force, in that I just use theMC.graphics.clear() and a loop of lineTo()s for every graph refresh. While this displays correctly (and I can control the refresh rate to mitigate the CPU burn), it should be painfully evident why I want to move away from this method.
I want to programatically scroll or pan the entire graph one pixel to the left (and drop the leftmost line), and then just draw one new line on the right, but I can't figure out where to start. Assuming such a thing is possible in AS3, would someone be so kind as to point me in the right direction?

View 1 RepliesFlash: Improve Performance By "breaking Apart" Graphics And Creating Symbols?
Mar 18, 2011In flash, if you have a complicated graphic (like a complex diagram) that doesn't change much and you want to move/zoom/rotate it around, then does Flash perform better if you convert all graphics into symbols? Or does making symbols slow things down?
Background: Sometimes, you do things for so long, you can't remember why you started in the first place. Whenever I import graphics in flash (like from Illustrator, for example), I select everything, press cmd-B (or ctrl-B on Windows) repeatedly, "breaking apart" everything until I can't, anymore. Then I press F8 and create a symbol.
That's just what I've done for like the last 10 years. It's to the point where I don't even think about it, anymore. I vaguely remember doing this after learning that performance improves when you break apart graphics to create a symbol.
Now, I have a problem: I'm translating/rotating/scaling a massively complex, static diagram and it's too sloooow. I'm trying every technique I can think of to speed things up—every little bit counts.I've read this link and lots of others but I haven't come across the topic of creating symbols.
Summary:should I go back through and make everything a symbol? Should I go through and make everything NOT a symbol? Which is faster?

Jul 31, 2009For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

ActionScript 2.0 :: How To Simplify And Improve Code
Feb 14, 2007Been reading up on the flash transition object. I came up with this way of fading out one clip and fading in another and having them loop forever using the transition objects but it's very dirty coding and not very flexible.
Is there a way to clean it up so that I can add as many clips as I want without having to write more code, just by adding more movie clips to the stage?

View 2 RepliesProfessional :: Reduce Mp3 File Size?
Dec 24, 2011So I have this .fla file that a freelancer made for me before. I noticed that the mp3's he imported have really low size of about 800kb only for each sound. When I sent this songs to him, they were in WMA files and have 3MB size each. I noticed that the file location says "program files/total video converter/...", so I assume that he used the Total Video Converter software to convert the WMA to MP3. But how was he able to make the size to only 800KB? Because I tried other converters and the size doesn't change significantly. Lastly, I noticed that it says in the properties "50.0% of original" and the use imported mp3 quality is checked! Also, since the above situation has a WMA file. How about if I already have the mp3 file? How can I reduce the size?
