Better DVD Performance

My iDVD project has an intro video, a main menu, and 4-5 submenus. The main content is 83 minutes long. I had to burn it on "Best Quality" instead of "Best Performance" because of the length and now the performance is poor and it often glitches. Sometimes the intro video doesn't play or is clipped, sometimes the main menu does not enable selection options, and sometimes cuts between black and video clips show rough (if that makes sense.)
I need to fix the glitches...if there's a way...should I reburn on a higher quality DVD? Should I double layer it and then burn on "Best Performance." Is that a possibility for me? I have to make a lot of copies of the master, so it needs to be glitch free...
Any suggestions?
Thanks!

By all means , if your drive supports it ....double layer it and then burn on "Best Performance."
Use Verbatim & burn at 4x or slower....best to do this from a disc image btw using apple's disc utilities or toast.

Test the image prior to burning w/ "Apple's DVD Player" app and not iDVD's Preview function.

What are the better load/performance testing tools available for Flex Application with BlazeDS RO?

In my application is designed with Flex3, ActionScript3, BlazeDS Remote Objects.
Just i tried with OPENSTA but i cant do the dynamic parameterization in their generated scripts because the response of the calls is binary values and also we cant get the response using with SCL language.
While testing with OPENSTA with HttpService, i can do the dynamic parameterization and got the response.
can give the information about the below questions
whether we can do dynamic parameterization with OPENSTA for Flex Remote objects?
and what are the better load/performance tools available for Flex Remote Objects?

Your approach is fine, depending on how many and what type of CFCs you are talking about. If they are "singletons" - that is, only one instance of each CFC is needed to be in memory and can be reused/shared from multiple parts of your application - caching them in the application scope is common. Just make sure they are thread safe ("var" or local.* all your method variables).
You might consider taking advantage of a dependency injection framework, such as DI/1 (part of the FW/1 MVC framework), ColdSpring, or WireBox (a module of the ColdBox platform that can be used independently). They have mechanisms for handling and caching singletons. Then you wouldn't have to go to the application scope to get your CFC instances.

DO's & DONT's for a better application performance

I am very new to tuning. What are the sql & pl/sql do's and dont's and best sql & pl/sql practices for a better application performance?
I was told by somebody to check explain plan for tuning db & sql statements. But i am bit confused by seeing the explain and don't know from where i have start and what i have take into consideration from explain plan to improve application preformance?
Can somebody help me in this regard?

> I am very new to tuning.
Good. Not having to tune means that the code is performing as it should.
And this is THE MOST IMPORTANT CONSIDERATION.
Do not write and design code that needs to be tuned and twisted and modded in order to perform. Write and design code with the core requirements of that code being:
- performance
- scalability
- flexibility
- maintainability
Good design = good code = good performance
No amount of tuning can turn bad code and a bad design into a well performing and scalable system. Which is why I dislike the concept of "tuning code". Start with a good and solid design. In other words, tune that before the code.
> What are the sql & pl/sql do's and dont's and best sql & pl/sql practices
for a better application performance?
The 1st basic rule is actually quite simple.
The "data layer" rule: Maximize SQL. Minimize PL/SQL.
Do not do in PL/SQL what SQL is very capable of doing. Fact. No other language is faster and better than SQL at crunching data in the Oracle RDBMS.
The 2nd basic rule is a logical extension of the 1st.
The "application layer" rule. Maximize PL/SQL. Minimize Java/C++/C#/Delphi/VB/etc.
Do not do in a 3rd party language what PL/SQL is extremely capable of doing. Fact. No 3rd party language is as capable as crunching data in the Oracle RDBMS as PL/SQL.
Stick to these two fundamental rules and your Oracle application will have a solid foundation for being a well performing and very scalable solution.

Is there anyone with *better* battery performance on the 3GS?

OK, there are a lot of posts complaining about the 3GS battery life. I'm now curious to find out if there's a bad batch of batteries, or if it's a software issue involving all iPhone 3GS.
My question: is there anyone out there who's getting better battery performance on the 3GS when compared to the 3G, as advertised by Apple?
I understand that there are at least 3 kinds of battery issues showing up in this forum:
1. abysmal battery life caused by Exchange Push acting up
2. defective battery
3. "it seems a little worse than the 3G, something must be wrong"
There's nothing that can be done for categories 1 and 2, and I think it's interesting to talk about case 3.
Could it be that the 3GS battery indicator is simply more linear (and better calibrated) than the one on the 3G? I am one of those people experiencing subjectively worse battery life on my 3GS when compared to the 3G. But then I stopped and asked myself how I actually measure this.
Well, the difference is that the 3G stays at 100% much longer, then starts to go down very quickly. The 3GS, on the other hand, doesn't like staying at 100% and starts going down earlier but slower. But if I let them both drain, the performance at the end of the day will probably seem similar.
I tried to drain my 3GS with some heavy Safari surfing over WiFi and 3G, 30 minutes of 3G calls, using some third party apps, and with a 1-hour Peggle play. Then I finally played some videos, and it went dead after 5 hours of usage and 15 hours of stand by.
Is that the performance that can be expected, or can we hope for more? I never did the same test on the 3G, because I never noticed the battery meter going down like that, but I'm pretty sure it would turn out quite similar.
What do you think?

Battery performance depends on what you have running on your iPhone.
e.g. If you have Brightness set to high (or full) with Auto Dimming Disabled, Locations Services, Push Notification (set Fetch to Manually), Bluetooth, Wi-Fi (ask to join networks enabled too) and 3G all enabled your battery will get used a lot quicker, especially if you use Third Party Apps on top of all these other things.
If however you activate Wi-Fi when you want to use it, or Bluetooth etc as your needs require, battery performance will be better (as in your battery will last longer before requiring a charge). If you are on a low 3G coverage area, why have your iPhone constantly trying to join a 3G network? Switch 3G off and use the conventional carrier (2G) until you return to an area where you know 3G coverage is better.
I know these measures are less convenient than just having everything switched on, but if you want to maximise battery use between charges try activating the features you require when you require them, then disable them when you don't require them instead of having everything switched on permanently.
I have noticed when Push is enabled (3G has to be enabled also), it absolutely canes the battery

Which makes a better DVD? Dynamic link or Encoder?

Which makes a better DVD?—to use the adobe dynamic link on a sequence in the project panel…
or to export to a file with the Adobe Media Encoder and then import into the Encoder?
If the latter, does it make a difference if I export from Premiere to an H264 or using the MPEG2-DVD option?
It would be simpler to burn to an H264 because that is the same file type that I upload to Youtube.
(Since MPEG2-DVD creates separate video and audio files, I assume they are not uploadable to Youtube…)
Thanks for any advice you can give.
[Font corrected.]
Message edited by Jim Simon

Export from Premiere with mpeg2-dvd.
Import the two files in Encore.
Make menu and burn.
If you use H.264 it gets re-encoded in Encore.
If you want to upload to YT with mpeg2 just set the Multiplexer to ON. H.264 is a better choice for YT.

Subquery vs UNION, which is better for performance?

I want to know which in better for performance using a subquery method or a UNION?
Any information would be helpful and appreciated!

Hi,
It depends on the SQL statments and each case is different from an other one. Take a look at the oracle doc: "Designing and Tuning for Performance".

Better audio performance

Does anyone know of a pci e or external option for getting better audio performance on a consumer level?
I have software; I'm searching for hardware options.
I realize its not an iTunes question, but figured ya'll might have some ideas.
Thanks

A new audio interface won't help.
You should start by getting an external 7200 RPM Firewire drive to put your audio on. That right there will help, especially with higher track counts.
Secondly, get more RAM. 768 of RAM is borderline for Logic. I always recommend at least 1 gig. Go ahead and max out that Powerbook to 2 gig of RAM, if you can.
All that to say, an Intel mac would be a huge improvement over the Powerbook. And if you do go that route, still get an external FW drive for audio, and as much RAM as you can afford.

How to make better DVD's and eliminate aliasing

After trying several different ways on how to get the best from my AVCHD camera to an SD DVD I discovered the following worked best.
1. Import and edit as per normal
2. Export to HD 720p (DON"T share to Dvd Studio Pro or iDVD)
3. Open iDVD and import the HD 720p file directly from the saved folder (iDVD will convert it to mpeg 2)
4. If using DVD Studio Pro you will need to convert the HD 720p file to Mpeg 2 using Compressor as normal.
5. Burn dvd.
This way eliminates nearly all of the aliasing problems and overall quality looks much better than just "Sharing" directly to iDVD or DVD Studio Pro.
Give it a try and let me know if your dvd quality improves.
Hope this helps.
Cheers
Paul

First of all; your way of attacking this is creating a very specific subVI. It is a general rule that subVIs should be as reusable as possible, so they should just perform a task upon some standardized input. That's why i suggested that you use an array input (but forgot to mention why...).
I've attached a small example of how i would handle this sort of problem. See the attached VIs, the subVI only handles the task of setting visibility on or off. The array input is dynamic in size, as opposed to the cluster, so any size 1D array of control refnums can be passed to it, using the boolean input to determine visiblity setting.
Your other question; yes it is possible to reach the control references from inside a subVI by passing the "This VI" reference to the subVI. But again, you'll have to change the subVI or make a different one for each different set of visible/invisible controls for it to work. Which is why i recommended building an array of just the refnums of the controls you want to set visibility for, and pass it to the subVI.

Which is better for performance Azure SQL Database or SQL Server in Azure VM?

Hi,
We are building an ASP.NET app that will be running on Microsoft Cloud which I think is the new name for Windows Azure. We're expecting this app to have many simultaneous users and want to make sure that we provide excellent performance to end users.
Here are our main concerns/desires:
Performance is paramount. Fast response times are very very important
We want to have as little to do with platform maintenance as possible e.g. managing OS or SQL Server updates, etc.
We are trying to use "out-of-the-box" standard features.
With that said, which option would give us the best possible database performance: a SQL Server instance running in a VM on Azure or SQL Server Database as a fully managed service?
Thanks, Sam

hello,
SQL Database using shared resources on the Microsft data centre. Microsoft balance the resource usage of SQL Database so that no one application continuously dominates any resource.You can try the
Premium Preview
for Windows Azure SQL Database which offers better performance by guaranteeing a fixed amount of dedicated resources for a database.
If you using SQL Server instance running in a VM, you control the operating system and database configuration. And the
performance of the database depends on many factors such as the size of a virtual machine, and the configuration of the data disks.

Choosing between SQL Server in Windows Azure VM & Windows Azure SQL Database

How to get better graphic performance on my Satellite C850?

Hi.
I have a problem with my *Toshiba Satellite C850-B253* and The problem is of graphic,in my PC when i run "**PES 2013**" the game warned to me even my *GPU* is not minimum and is very low to open this program.
Please give me a issue that the game and my computer work better of past.
Thank you

Listen dude
You bought this notebook Satellite C850-B253 which is equipped with an Intel HD Graphics 4000 with shared memory (memory amount : up to 1,696 MB shared memory with 4 GB system memory installed (with pre-installed 64-bit operating system)
Dont expect too much from this internal graphic chip.
Your game is new and requires great GPU performance. If you are a gamer, you should purchase a notebook with an external GPU like ATI or nVidia.

Which is better from performance point of view : Enum or String?

Hello All
While working to re-factor code so as to improve performance,I saw that repeatedly some Strings are used to be put as keys in a HashMap.
Will there be an improvement in performance if I assign use enums in place of using double quoted strings everytime.
Also,Is it a better idea to use string constants rather than enums.
Can anyone help me over this?
Thanks in advance
Mansi

Found an article in Java performance tuning book.But they nowhere mentioned the perfect reason for doing this.Here's the artice :
Enumerating constants
Another canonicalization technique often used is replacing constant objects with integers. For example, rather than use the strings "female" and "male", you should use a constant defined in an interface:
public interface GENDER
public static final int FEMALE=1;
public static final int MALE=2;
Used consistently, this enumeration can provide both speed and memory advantages. The enumeration requires less memory than the equivalent strings and makes network transfers faster. Comparisons are faster too, as the identity comparison can be used instead of the equality comparison. For example, you can use:
this.gender == FEMALE;
instead of:
this.gender.equals("female");

File Or Proxy Which is better in Performance?

Hi Friends,
In one scenario we are sending data from R/3 to legacy System.. The amount of Data Could be around 2000 records(Each record having just 5 fields).. For retreiving data from R/3 we are thing of going for Proxy... At the same time we are thinking of useing File adapter for reading data from R/3.we will write that data to a file and then transfer .... My doubt is which is the better way to do it...And in which type of scenarios using File for Reading R/3 data is suggested....
Regards,
Shyam M.

Yes the Proxy will be direct communication with integration server.
But with file you need to have the File adapter to conver it to XML format before reaching upto Integration server. While dealing with high volume of data this will affect lot on the performance.
Actually above 80MB there might be problems with memory on your abap stack.
Upgrade the configuration of Integration Engine.
Here you need to increase the Memory size as well as paging and heap size. It will allow you to have max utilization of memory for such vloume of data.
Thanks

Better TIFF Performance

Hi,
I would like to display TIFF images in a JPanel more quickly than I do now.
Currently, I use this JAI code :
       PlanarImage pi = JAI.create("fileload", "C:\\image.tif");
       ColorModel colmodel = pi.getColorModel();
       Rectangle rect = new Rectangle(new Dimension(pi.getWidth(), pi.getHeight()));
       BufferedImage buf = pi.getAsBufferedImage(rect, colmodel);And here I have my BufferedImage that I can display in my JPanel.
That's works, but that also does have very bad performances : it needs a few seconds to open a simple TIFF G4 (Bilevel, B&W) image.
Does someone know a better way to load TIFF images with JAI ?
Thanks.
Hugo.

Hi,
I don't know if this will lead to a performance boost but try this
load method:
public BufferedImage loadImageAsStream(File f) throws IOException {
        SeekableStream s = new FileSeekableStream(f);
        // maybe params for your tiff-file
        TIFFDecodeParam param = null;
        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", s, param);
        // Which of the multiple images in the TIFF file do we want to load
        // 0 refers to the first, 1 to the second and so on.
        int imageToLoad = 0;
        // older version
        RenderedImage op =
                new NullOpImage(dec.decodeAsRenderedImage(imageToLoad),
                null,
                null,
                OpImage.OP_IO_BOUND);
        BufferedImage buf = null;
        //System.out.println("Colormodel " + op.getColorModel().getColorSpace().getType());
        // tiff with one subimage
        if (dec.getNumPages() == 1) {
            buf = PlanarImage.wrapRenderedImage(dec.decodeAsRenderedImage()).getAsBufferedImage();
        else{
            // do load all pictures of a tiff ...
        return buf;
    }Olek

Why using workarea for internal table is better in performance

Please tell me
why using workarea for internal table is better in performance

Hi Vineet ,
Why would we choose to use an internal table without a header line when it is easier to code one with a header line?
it has following reason.
1)Separate Internal Table Work Area:
The work area (staging area) defined for the internal table is not limited to use with just one internal table.
take ex-
Suppose you want two internal tables for EMPLOYEE one to contain all records and one to contain only those records where country = USA. You could create both of these internal tables without header lines and use only one work area to load data into both of them. You would append all records from the work area into the first internal table. You would conditionally append the USA records from the same work area into the second internal table.
2) Performance Issues: Using an internal table without a header line is more efficient than one with a header line
3) Nested Internal Tables: If you want to include an internal table within a structure or another internal table, you must use one without a header line.
If this one is helpful ,then rewards me
Regards
Shambhu
