I have the same problem, and add this replay to motivate a clever person to solve this problem.
My situation is:
20 Applets (or so) on one page - they span exactly on Thread - if clicked. And if I reload the page they never work again - I have to restart the browser.
If I browse to the page with the applets I have complete browser crash in 3 of 4 cases. But the first time I visted the page after reboot of Linux (everything less don't help) all the applets work.
If I put only one Applet on a page and reload this page, then in a few lucky cases the Applet works a second time.
On windows everything is fine, so I don't think my
Applets are the problem.
On linux I tried several version of upto Mozilla 0.9.8
everytime the same (but 0.9.8 don't work at all with the plugin).

I recently upgraded to 10.6.7 and Safari 5.05. Safari now has a long load time when you initially boot it up and when selecting a new tab. Other than that it works fine. What can I do ?

Check Safari / Preferences - Extensions. If you have any installed, turn that off, relaunch Safari.
If it's not Extensions, check for third party Safari add ons.

My screen load times have slowed down to a crawl. I have to wait and wait for a page to load. (I know --dial -up) It used to be much faster a month ago before 5.0. Is it FireFox or do I look to Yahoo for the problem? I don't know how to sort it out.

I'm having the same problem. Dreamweaver is supper slow. Uploading and downloads from the server... any server I use two different servers. It times out all the time. Menus are slow too.
I'm on a MAC Pro, 6 gigs of ram no issues with anything else. I have talked to Apple they have checked everything for me. They say it's Dreamweaver. I've noticed the Dreamweaver is talking to the FTP even when I'm not doing anything.
I've tried cleaning out my MAC caches, turning off file check and check out. Still really slow. I've worked with Dreamweaver for 6 years never any issues like this before. 18 seconds to upload a 4 kb file. 11 seconds to download the same file.

How can i reduce applet loading time?

I have recently begun converting a gui application to an applet. The problem i have is the loading time of the applet which can be several minutes.
The gui has a progress bar which tracks the loading of the classes, images and sounds etc, once this is up and running the loading time is fairly short, however it takes forever for the gui to actually begin to display.
The code for the classes is only about 150K altogether, there seems to a period of long modem inactivity once the applet is initialized before the gui is displayed.
How can i reduce the time it takes for the applet to initialize before the gui is displayed, otherwise users will thing nothing is happening and not bother loading it.
the applet is currently at http://www.winnieinternet.com/games/startrade2095/applet/startrade2095.htm
if you need a demo of the problem, although the applet is still work in progress.
Many thanks in advance for any help

Some suggestions could be:
1. Bundle all classes and resource files in a jar file.
2. Try to preload the heavier files (e.g. sound files) in a background thread, instead of init() method. See an example for this in Sun's Java tutorial, under the trail 'Sound'.

J2SE 5.0 plugin and slow applet load time

Folks,
I have an applet (https), with about 5 MB of jar files. After we
moved to J2SE 5.0, the load time seems much slower. It used to load in
40 seconds. Now it loads in 4 min.
An odd thing I noticed is when I minimize my Internet Explorer window,
the applet seems to start up quickly again.
Is this possibly related to the "starburst logo" progress bar
animation that Sun now uses for applet start ups? I know that
animated gifs can sometimes chew up quite a bit of cpu time.
I think the progressbar property is no longer in 5.0
I'm running on a single proc laptop. When I run it on my 2 proc
server, it is not as obvious, and startup time seems reasonable.
Thanks,
Rob

I'm also seeing a similar slow applet startup time. CPU is 100% (IE is in high 90s). Works ok on my 3GHz P4, but is very slow (up to 16 minutes) on 400 MHz P2.
My problem seems to be related to how my .properties files (23 total, for internationalization support) are handled.
During start-up in JRE 1.5 I see the following for each .properties file:

The file (1 of 23) I supply is named fax.properties (the default file). Since my locale setting are English/US I guess the I18N code is trying to figure out if the regional files are present. Each of these requests is timing out 5-8 seconds for each - it builds up quickly.
I haven't been able to find out why this is happening or resolve the issue. I'm close to restricting my applet to only 1.4.2 as that was fine and posting this as a bug.

Very long applet load time with JRE 1.5 - HELP!!

My applet is taking forever to load and init using JRE 1.5.
With JRE 1.4.2_06 it takes a matter of seconds to load and init. The same 1.4.2_06 compiled code running on JRE 1.5 takes ~ 17 minutes!!! Is anyone having a similar experience? I've seen other similar posts related to past plug-in versions, but nothing related to 1.5. The same problem occurs if I compile the code with JDK 1.5 and run with JRE 1.5.
This extreme example happens on a 533 MHz Win2000 pc with 524 MB RAM.
A desktop with 3 GHz P4, 1 GB RAM running WinXP SP2 doesn't have an appeciable delay (a couple seconds).
A laptop with 2.21 GHz AMD Athlon 64, 512 MB RAM running WinXP SP1 takes about 8 seconds to load the applet.
I don't believe it's running yet in the init method during this long wait time. I don't see any print statements, but the basic layout of it is the following:
     public void init()
          applet = this;
          // Setup Look and Feel
          try
               UIManager.setLookAndFeel (UIManager.getSystemLookAndFeelClassName());
          catch (java.lang.ClassNotFoundException e) {System.err.println("Error setting Look and Feel.");}
          catch (javax.swing.UnsupportedLookAndFeelException e) {System.err.println("Error setting Look and Feel.");}
          catch (java.lang.IllegalAccessException e) {System.err.println("Error setting Look and Feel.");}
          catch (java.lang.InstantiationException e) {System.err.println("Error setting Look and Feel.");}
          // Setup background coloring
          HeaderFile.bgcolor5 = UIManager.getColor("Panel.background"); //new Color(212,208,200);
          HeaderFile.bgcolor6 = UIManager.getColor("desktop");
          applet.getContentPane().setBackground(HeaderFile.bgcolor6);
          // Splash screens
          urlSplash = getURL("AesGuiLarge.jpg");
          ImageIcon_Splash = new ImageIcon(getURL("OmniViewSplash_noWords.jpg"));
          ImageIcon_OmniView = new ImageIcon(getURL("OmniView_wordOnly.gif"));
          // Setup Intitialization panel
          final InitializationPanel initPanel = new InitializationPanel();
          contentPane = getContentPane();
          if (preRelease == true)
            Label label = new Label("PRE-RELEASE");
            label.setFont(new Font("SansSerif", Font.BOLD|Font.ITALIC, 11));
             JPanel panel = new JPanel();
               panel.setBackground(Color.yellow);
               panel.add(label);
               contentPane.add(panel, BorderLayout.SOUTH);
          contentPane.add(initPanel, BorderLayout.CENTER);
          Thread initialize = new Thread ()
               public void run()
                        System.out.println("\n***** Initialize thread start *****\n");
          initialize.start();
     }Any help would be appeciated.

I've discovered where the bulk of the delay is coming from.
I have 23 default *.properties files in my project. These files contain the English translation of all displayable strings for Internationalization (I18N). The default naming convention is "text.properties".
For those who don't know I18N, here's a brief synopsis of what happens. ResourceBundles are used to get the strings that are displayed. if your local computer's language/regional settings are English/US, then when the ResourceBundle searches for the file that contains the strings it first looks for a file named text_en_US.properties. If that file is not present or the string is not located, it then looks for a file named text_en.properties. If that file is not present or the string is not located, it then looks for the default file named text.properties. My properties files are all default named.
I used the Java Console tracing capability to see what was happening and this is what I saw. This is happening for every .properties file:

None of the files in these traces exist. JRE 1.5 is attempting to set cookies on each of these non-existent files. There is approximately a 5-8 second delay that occurs before each attempt times out. So for each of my 23 properties files this translates to 575-920 total seconds (or 9-15 minutes).
I tried turning off cookies, but the timeout still occurs.
Can anyone explain why this is happening and how to fix it?

Applet Loading Time - Urgent

I am facing a problem on one of our production sites. The APPLET(deployed on weblogic server) is taking a huge time to load, of the order of 15 minutes. Even after it is cached on first time loading, the subsequent access to APPLET still takes same time.
Whileas in our testing we didn't encounter such problem. Of course, at customer site i see that the machine using IE(client) is on a different LAN than the weblogic server whileas most of our in house tests were done on same LAN
what could be the possible reasons for this?

Some suggestions could be:
1. Bundle all classes and resource files in a jar file.
2. Try to preload the heavier files (e.g. sound files) in a background thread, instead of init() method. See an example for this in Sun's Java tutorial, under the trail 'Sound'.

Using Flash Player 10's Cocomo.swc got you down?

Hey everyone. I'm posting this in hopes it will save someone
a bit of time.
I was playing with Cocomo today and hit a wall dealing with
the Flash Player 10 version of Cocomo.swc and Adobe AIR. I created
a new AIR application in Flex Builder 3, and pointed it to the Flex
SDK 3.2. I then linked in the FP10 version of Cocomo.swc.
Everything was going fine until I tried to run my application and
it threw "Error #1065: Variable SoundCodec is not defined."
After doing a bit of research, I learned this error occurs
when trying to run Flash Player 10 code in the Flash Player 9
runtime. I thought Flex Builder would handle this for me
automatically when I pointed it to the 3.2 SDK.
Anyways, here is the fix.
In your AIR project do the following:
- Project > Properties
- Choose "Flex Compiler"
- Add "-target-player=10" to your Additional compiler
arguments
- Hit OK
Hope it helps someone :D
EDIT: Fixed the list of steps

Hi,
Can you please post the detailed changes you made in your air
properties ? As the previous post regarding details seemed to be
blank.
Thanks

Load Time and MP3

Hi,
I am revamping a program that was originally done in Captivate 3. All of the sound files were recorded using another program and imported. They were originally in WAV format. The file size is huge on this thing and the load time is (to me) excessive. I eliminated a couple of the videos and coverted about 50% of the WAV files to MP3 and reloaded them. I also made sure I cleared the unused items from the library. Unfortunately the CP file size has remained the same and the load time is still long. Can any of you give me some thoughts on how to cut this thing down?
Many thanks in advance for your help!
Gary

Hello,
How did you check the CP-filesize? Can you please save the file, close Captivate, and then reopen it with the file? Have a look at the filesize then? The decrease of file size is not immediately visible, but do know that clearing up the library, and certainly deleting video/audio does decrease the filesize really. WAV-files will be converted to MP3 anyway when publishing to SWF, unused items in the library do not have any influence on the SWF-size either. Perhaps you are not talking about the CP-filesize but about the SWF-size (because you are referring to load times). To decrease the filesize for the SWF you'll have to look to other means: decrease the resolution (if acceptable, by downscaling), decrease the JPEG-quality, decrease the audio quality. To make the loading time smaller you can also change the percentage to load before starting to play the SWF (default=100%, see Preferences, Project, Start and End).

Flip4Mac Beta, Slow WMV load time?

Just wondering if anyone else who is using Flip4Mac Beta Universal is experiencing slow load time when loading a WMV movie file. I loaded a 1920x1200 606MB video file and that might be why. Anyway, just wanted to see if anyone else is experiencing slow WMV load time.

Like you I've noticed that when working with larger media files it'll slow down loading and other aspects. Especially moving through said files by fast forward/reverse.
I wouldn't exactly call it too bad though. QT native files get slowed down the larger they are too.
Don't forget it's still a Beta.

Updated to 4.0 version and when it loaded I got 4 identical icons on my desktop. I went back in time on my computer and now Firefox won't open.

Updated to 4.0 version and when it finished loading I got 4 identical Firefox icons on my desktop. I went back in time on my computer to go back to an order version and Firefox won't open or is very slow to open.

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

For about the past week, Facebook has been taking forever to load (or just not) on my mac (OSX 10.5.8; Safari 5.0.6). Other sites are fine. I routinely empty the cache, clear history, cookies, etc. each time I shut down. Suggestions?

For about the past week, Facebook has been taking forever to load (or just doesn't) on my mac (OSX 10.5.8; Safari 5.0.6). Other sites are fine. I routinely empty the cache, clear history, cookies, etc. each time I shut down. Suggestions?

I don't use Facebook, but I can say that clearing the cache every time you shut down is excessive - unless you're sure the cache is corrupt you should leave it alone. It exists to speed up your browsing experience by loading frequently requested items from your drive rather than downloading them fresh from the internet each time. So, I would say stop clearing your cache and see what happens.
As for clearing cookies: I'm not sure what method you currently use, but I would recommend you download and install CCleaner. It's free, and allows you to build up a list of cookies that you want to clear and those you want to keep, before deleting them.
Both of these may help speed things up by reducing the amount of work Safari has to perform whilst browsing. Regardless, I'd say that, unless there's a reason you've not mentioned for performing the "purging" that you do, making these two changes should see improvements in general web browsing if not specifically when loading Facebook.

Java applet loading for a long time.

If you go here (warning - long load to start with) -

I have placed a newsticker java applet there but when you first visit the site the browser freezes up for a while untill the applet loads.
Any idea on whats causing this to load so much?
Thanks.
