Can changing SWF version improve performance?

Are there performance improvements in each new Flash Player? And if so do you have to set the swf-version to an updated value?

In Flash Player, SWF versioning is primarily a mechansim for maintaining backwards compatiblity.
New features are tied to the version where they're introduced, but the important distinction is that we offer bug-for-bug backwards compatibility, with security as an exception.
If we encounter an API that works incorrectly in previous versions and the fix is likely to break existing content, we'll version-check the fix and apply it to only versions equal or greater to the SWF version where it's introduced.
I can't think of a good example where we've version-checked a performance fix off the top of my head, but it's definitely within the realm of possibility.
TLDR; You'll probably want to publish to the highest SWF version unless you have a good reason not to, especially now that background update is widely deployed.

ANALYZE TABLE mf1 ESTIMATE STATISTICS SAMPLE 5 PERCENT FOR ALL INDEXED COLUMNS
This is the function I would like to achieve better performance on, or rather it is the query in cursor c_query. I have a larger application that does a lot more, but we have found that the most time consuming part is doing the c_query on various cnxid so I figured a function like this would be a decent test to see how it performs without having to run the entire application.
CREATE OR REPLACE FUNCTION test1 RETURN NUMBER AS
CURSOR all_cid IS SELECT distinct cnxid FROM mf1;
all_cid_row all_cid%ROWTYPE;
sum_val NUMBER(19,0);
CURSOR c_query(in_cid IN NUMBER) IS SELECT /*+ INDEX(mf1 mf1_cid_ts_idx)*/ * FROM mf1 WHERE cnxid = in_cid ORDER BY ts;
c_query_row c_query%ROWTYPE;
BEGIN
sum_val := 0;
FOR all_cid_row IN all_cid LOOP
FOR c_query_row IN c_query(all_cid_row.cnxid) LOOP
sum_val := sum_val+1 ;
END LOOP;
END LOOP;
RETURN sum_val;
END;
I added a hint in the c_query for which index it should use. Without the hint it use mf1_cid_idx and performance is better with mf1_cid_idx.
Runnig the SQL tuning advisory from enterprise manager I am told to analyse the table, which I though I did and to get another CPU.
I have tried changing the analyse to this without any effect:
begin dbms_stats.gather_table_stats(ownname => 'MARIUS', tabname => 'MF1', estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt=>'FOR ALL COLUMNS SIZE AUTO'); end;
I have tried clustering, but the way I insert tuples to the mf1 table achieve much the same as long as no new tuples are inserted. In other words when I tried clustering it I got the same performance.
Another thing I have been wondering is that if I populate the mf1 table with 10MB 100MB 1GB 5GB the amount of time per MB of data decreases to a low point at 5GB and then dramatically increase if I populate the mf1 table with 10GB.
The tablespace containing mf1 is 44GB large it only contains one incarnation of the mf1 table. It has a maximum 13GB used when I populate the mf1 with a 10GB table. temp is 8GB, undotbs1 8GB
Any suggestion how I can imporve my c_query?

I''m looking at the bulk transfer, actually I'm running tests to see how it perform. I was wondering if some one that was familiar with BULK transfeer could have a look at my new test1 function to see if it is equivalent to the old one. (Added the old one to the bottom for ease of reference).

How much can a native compiler improve performance of a java application?

Hello,
we have a customer with low-end machines who complains very much about the
starting time of an application of us. I dont't know the exact configuration
of the clients but i think the bad perfrmance is because the client has too
few memory and has to swap when the jvm starts.
Could a native compiler like Excelsior JET be a solution or would the
imporvement be only marginal?
Anyone who has experience in this topic?
Thank you in advance!

Could a native compiler like Excelsior JET be a solution or would the
imporvement be only marginal?Excelsior JET only packages up the class files and a JRE into a big blob so that it looks like a single executable. It doesn't actually generate native code for your classes.
There are some limited pure-native compilers (e.g. GCJ - the GNU compiler for Java). Because you also need native-compiled libraries, and those are quite incomplete, only certain basic programs can be compiled down to native form without some major tweaking today.
As to whether it'll improve your performance or not: if your program is computationally intensive (does lots of floating-point math, or other CPU-intensive algorithms), it may improve. If it's I/O, network or database bound, you'll see very little improvement, if any. If it's graphics-bound, you may see some improvement, though the native Swing support with GCJ is limited at this time.
Even with long computationally-intensive programs, you may or may not see an improvement. If you use the server VM (java -server ...), then it does similar things behind your back (optimizing compiles), so that eventually your program speeds up a fair amount (though not to pure-native speeds).

How to improve performance on MacBook Pro 10.5.8?

I have a MacBook Pro running 10.5.8 that has become way too slow. It hesitates between key strokes and response and is slow to search and navigate websites.
I just checked and there are no updates due.
What can I do to improve performance?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are several lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
Some of the commands will line-wrap in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search. A text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” (without the quotes) and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag -- do not type -- the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/ {print $6 $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.apple/ {print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple/ {print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* L*/Fonts 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, change it to something like “[email protected]” before posting.
Step 5
osascript -e 'tell application "System Events" to get the name of every login item'
Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

Load swf-version=17 into swf-version=10 - VerifyError: Error #1014.......

Hi Guys,
I have very interesting situation, and I would like to ask you for any help.
History: I've started the new project for "one" company (my project is small web game). The first and the main requirement for this project was using Stage3D. The company I'm working for, has it's own "SWF-Container" for all projects (about 1000+ small projects). The second requirement was using this "SWF-Container" to load my project inside.
Main Issue: "SWF-Container" can't be changed/modified (a lot of functionality + a lot of project already online). "SWF-Container" wroted using Flex SDK 3.6 ("A long time ago in a galaxy far, far away...." ) -swf-version=10. When I'm trying to load the new project ("-swf-version=17") into this old container - I'm receiving the error:
[Fault] exception, information=VerifyError: Error #1014: Class flash.display::Stage3D could not be found.
(and I thing the same will be for all new classes like: JSON, Context3D, etc...)
No errors if I'm opening my project stand-alone.
My ideas/suggestions:
1) Ask for new "SWF-Container" - Failed. No resources to support a few "SWF-Container"s.
2) Ask for change "SWF-Container" to be "-swf-version=17" - Failed. No simple way to change SWF version using Flex SDK 3.6 + a lot of conflicts with current projects (at least global class "JSON").
3) Find some solution with loading the new SWF to the old SWF - in progress. Currently - with no success.
Projects:
I've created two project that simulate my situation: https://drive.google.com/file/d/0Bw4xj8VbNvNuZ1gybzFYcEpkLVk/edit?usp=sharing
By using next URL you can find ZIP with two FlashDeveloper projects inside:
a) OldContainer - project that simulate "SWF-Container" (Flex SDK 3.6)
b) NewGame - project that simulate my new project (Flex SDK 4.6).
I will be very grateful for any help in finding a solution for this problem.
With best regards, Vadym.

Hi kglad,
Thank you for good point. But there are no way to change current mehanisms to embed/load "SWF-Container".
Imaging, that "SWF-Container" is not a simple empty SWF, but it's site core, that display in one time a lot of different widgets - small AS3 projects with really different functionality (one of these widgets should be my small game).
Thanks, Vadym.

How to preload sound into memory to improve performance?

Hello all
I have an application where it needs to play 4 different short wave files on some events. The wave files are small (less then 1 sec each) so they can be preloaded into memory. But I don't really know how to do that.. This is my current code... Performance is really important here, so the faster users can hear the sounds, the better...
import java.io.*;
import javax.sound.sampled.*;
import javax.swing.*;
import java.awt.event.*;
public class PlaySound implements ActionListener
     private Clip clip = null;
     public void play(String name)
          if (clip != null)
               clip.stop();
               clip = null;
          loadClip(name);
          clip.start();
     private void loadClip(String fnm)
          try
               AudioInputStream stream = AudioSystem.getAudioInputStream(new File(fnm + ".wav"));
               AudioFormat format = stream.getFormat();
               DataLine.Info info = new DataLine.Info(Clip.class, format);
               if (!AudioSystem.isLineSupported(info))
                    JOptionPane.showMessageDialog(null, "Unsupported sound line", "Warning!", JOptionPane.WARNING_MESSAGE);
               else
                    clip = (Clip) AudioSystem.getLine(info);
                    clip.open(stream);
                    stream.close();
          catch (Exception e)
               JOptionPane.showMessageDialog(null, "loadClip E: " + e.toString(), "Warning!", JOptionPane.WARNING_MESSAGE);
     public static void main(String[] args)
          play("a wav file name");
}     I would appreciate it if someone can point out how I can preload them to improve performance... Thanks in advance!

The message above should be:
OMG, me dumb you smart Florian...
Thank you for your suggestion... It's not the best OR anything close to what I thought it would be, it's certainly one way to do it and better then what I've got now...
Thanks again Florian, I really appreciate it!!
BTW, is there anything that would produce the sound faster then this?

Hi there.
Some advices:
- why going to MVKE first and MARA then? You will find n rows in MVKE for 1 matnr, and then go n times to the same record in MARA. Do the oposite, i.e, go first to MARA (1 time per matnr) and then to MVKE.
- avoid select *, you will save time.
- use trace or measure performance in tcodes ST05 and SM30.
- replace:
select * from konp
where knumh = a004-knumh.
if sy-subrc = 0.
Check_ZPR0 = konp-kbetr.
endif.
endselect.
by
select * from konp
where knumh = a004-knumh.
Check_ZPR0 = konp-kbetr.
exit.
endselect.
Here, if I understood, you only need to atribute kbetr value to Check_ZPR0 if selecting anything (don't need the IF because if enters in select, subrc always equal to 0, and also don't need to do it several times from same a004-knumh - reason for the EXIT.
Hope this helps.
Regards.

Times ten to improve performance for search results in Oracle eBS

Hi ,
We have various search scenarios in our ERP implementaion using Oracle Apps eBS, for example searching for an item . Oracle apps does provide item search but performance is not great. We have about 30 million items and hence to improve the performance of the search thought Times ten may help.
Can anyone please clarify if Times ten can be used to improve performance on the eBS database , if yes how.

Vikash,
We were thinking along the same lines (using TimesTen for massive item search in e-Business Suite). In our case massive Item / parametric search leveraging the Product Information Management application. We were thinking about setting up a POC on a Linux Server with a Vision Instance. We should compare notes?

Improving performance when using LineStripArray?

I'm rendering approximately 680 LineStripArrays to represent an airport on a situation display. I read the data from a DXF file and I imagine I can strip that down by removing parts of the airport I don't want to show.
However, performance is poor - I'm probably hitting 50fps when I'm barely rendering anything. Apart from not displaying some LineStripArrays, what can I do to improve performance? Should I merge some LineStripArrays? Is there another geometry class I should use?
My code is:
               // This array will hold the vertices.
               float[] vertices = new float[count*3];
               // Create the colour.
               Color3f colour = new Color3f(1.0f,1.0f, 1.0f);
               // iterate over all vertex of the polyline
               for (int i = 0; i < count; i++) {
                    vertices[(i*3)+0] = (float)vertex.getX();
                    vertices[(i*3)+1] = (float)vertex.getY();
                    vertices[(i*3)+2] = (float)vertex.getZ();
               }And then:
layerData = new LineStripArray(count, LineArray.COORDINATES, strip_counts);
layerData.setCoordinates(0, vertices);Thanks

Yes, it will cause performance issues. Whether you notice it or not may be a different story.
LabVIEW drawing engine starts at the bottom layer and works its way up. So, it has to redraw the image and then redraw the control when you update the control/indicator.
It's been a while since I benchmarked this on a project, but in LabVIEW 6.1, I looked into why my tests ran so slow, and saw a 10-15% decrease in test time by removing the background decorations I used to make the window pretty. If I didn't show the GUI feedback for the test at all (no GUI windows for each test), I saw a 30% decrease in test time.
You will also find that better video cards will have a positive effect on this, as they redraw the screen faster. In the same benchmark, I was able to outperform the early PXI controllers with a slower PC because NI was using a lower end video chip for their onboard graphics.

Thanks for any help you can provide.

LR on your laptop is still a desktop version. It is just now able to upload to the cloud to replicate photos to either http://lightroom.adobe.com/ or an iPad that has LR Mobile installed.
I think you probably just want to change the LR 5 identity plate back so it doesn’t mention LR Mobile all the time. Hover over the identity-plate area, and click on the little triangle that appears, then choose Change Identity Plate.

System Preferences > Language & Text > Language.

In Internet Explorer, in the internet options, you can change the temporary internet files to check for newer versions of stored pages. Can this be done in Firefox? And How?

I just want to know how I can change the settings to check for newer versions of stored pages in Firefox.

There is a hidden preference that controls when Firefox checks for a newer version. # Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.cache.check_doc_frequency''', double-click on it to change its value
For details on the possible values of his preference see http://kb.mozillazine.org/Browser.cache.check_doc_frequency

Can changing SWF version improve performance?
