Problems loading applets - Very Slow
Ok... I have designed my applet in two parts implying that my applet consists of two .jar files, one for each part.
I Launch it by the following html-code:
<applet
codebase="games/"
code="testapplet.TestApplet"
archive="../games/testapplet.jar, ../gameengines/gameapplet.jar"
width="640"
height="480">
</applet>
This works GREAT on my local machine but as soon as I try to launch it om my webpage, it suddenly takes Ages to load! I don't get why. The jar-files are totally 51k so the size cannot by an issue...
Does the number of files packed in the .jar-files matter to how fast my applet loads? I thought I got around that problem by using .jar-files but ... ?
Thanx for you input!
/M
Hmmmm... Well, Would using HTTP 1.1 make my loading process any faster? I'm talking about 20 seconds load time for an applet consisting of 70 classes all packed in to two .jar-files at totally 51k.
No extra graphics, No GUI, No nothing - Except a Game API that has the potential to perform quite well, once it is up and running!
Are there any design issues that I perhaps have to take into consideration when I design Applets?

Youtube app loads videos very slow On my ipad mini
Youtube app loads videos very slow On my ipad mini . I can let it buffer for 10 seconds, it plays and then stops because it has to buffer again and convert the video in very poor quality. i have 20mb internet connection. my sofware version is iOS 6.1.3
Check your internet upload speed. You probably have a very slow speed.

Applet very slow and shows no activity, but its running
I have a new applet for the users, but I am reluctant to implement until I get some others opinions. It is very slow (30 - 40 seconds)
Before it outputs a screen with about 20 lines, it reads 90 different html files. It looks at the forth rec of each to extract a name. It also gets the file size to determine if the record needs to be on the screen.
Anyway, it does 4 reads on 90 files. = 360 reads. Oops, it also reads and loads a 80 record file at the beginning. So total is 440 reads.
It takes 30 - 40 seconds. Which is not horrible, but it is not good. What really bothers me is that the applet screen shows no activity. At the bottom is shows "done" and "100%". Task Manager shows no activity. But if you just let it sit there, it will finally fill the screen. Pretty amazing to me. I would much rather see a "progress bar" moving on the bottom like other screens. Actually, a progress bar would solve it, because the users are not in a big hurry anyway.
I am using "openStream" and "readLine" for the files.
Any opinions?

I would much rather see a "progress bar" moving on the bottom like other screens.Ah, I think I see where you're confused. The progress bar and applet loading subtitles, etc are Java's way of presenting the progress of loading the applet. Once it's fully loaded, though (which it is when your code starts running), it hands off control to you. It's in your hands at that point. -
Safari loads (freezes loading) webpages very slow on iPhone 4
Hi!
I have a problem with Safari on my iPhone 4 (4.2.1). Since I upgraded to 4.2.1 a week ago Safari is very slow and in 80% of time wont load webpages with first time when in 3G mode with strong bars. Well it loads them but very slowly (It takes approximately 20-30 seconds to load google or other pages). Maybe it would be more precisely to say that it starts to load, than the blue progress bar just stops at around 1/2cm and than after 20-30 seconds it actually starts to open the page and the blue progress bar continues to move. Sometimes (not often) after those 20-30 seconds I get message that page can't be opened cause server stopped to respond...
What is important to my mind is that if I press reload while Safari is loading a webpage it opens fast as it should. So it usually works with second try.
Since I noticed this problem after I upgraded to 4.2.1 I think those two things have connection (4.2.1 and Safari problem) but I might be wrong.
This is happening in different locations around the city and it is not problem with coverage...I have three, four or sometimes even 5 bars 3G.
Anybody having the same problem or can help me with some advice?
Thank you!Safari Problems

SQL loader load data very slow...
Hi,
On my production server have issue of insert. Regular SQL loder load file, it take more time for insert the data in database.
First 2 and 3 hours one file take 8 to 10 seconds after that it take 5 minutes.
As per my understanding OS I/O is very slow, First 3 hours DB buffer is free and insert data in buffer normal.
But when buffer is fill then going for buffer waits and then insert is slow on. If it rite please tell me how to increase I/O.
Some analysis share here of My server...................

Problem loading applet from tomcat
I am facing a problem loading the batik applet from tomcat. I have placed all the jar files of batik in ROOT directory in tomcat. Along with the folder containing the batik applet. Still i receive the following exception when trying to load the html page containing batik applet.
Applet tag in html page is:
<applet codebase = "." code="batik_applet.BatikApplet.class" name="myApplet" width="1600" height="1200" hspace="0" vspace="0" align="middle" archive="batik-swing.jar,batik-gvt.jar,batik-bridge.jar,xml-apis-ext.jar,batik-css.jar,batik-util.jar,batik-dom.jar,batik-svg-dom.jar,batik-anim.jar,batik-awt-util.jar,batik-codec.jar,batik-ext.jar,batik-extension.jar,batik-gui-util.jar,batik-parser.jar,batik-script.jar,batik-svggen.jar,batik-transcoder.jar,batik-xml.jar,js.jar,pdf-transcoder.jar,xalan-2.6.0.jar,xerces_2_5_0.jar,xml-apis.jar">
</applet>
I already have a folder named batik_applet containing BatikApplet.class in the ROOT directory.

Any help would be appreciated.Assuming that your applet is not in a jar file (don't see a value for archive)
you have a file callsed ProcessStatus.class in a folder WEB-INF\classes relative to
the location of the jsp file.
So if the jsp file is in
myJSPFileFolder
the class should be in:
myJSPFileFolder\WEB-INF\classes
If you want to see when the jre is trying to load and where it it trying to load it from you
can inspect a full trace, to turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
I think for linux this is somewhere in youruserdir/java (hidden directory)
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
for 1.5:
deployment.javapi.jre.1.5.0.args=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
I think for linux this is somewhere in youruserdir/java (hidden directory)
The trace should show something like :
Caused by: java.io.FileNotFoundException: http://server/location/filename.class (The system cannot find the path specified) -
Safari 8.0 loads pages very slow
Why does Safari 8.0 load webpages so slow now that I have installed OS X 10.10 - even the Apple.com page is painfully slow to load.
Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference? -
Hi,
We are using BAPI to fetch data from R/3, at the time of displaying it on the screen, page load is taking time, and scrolling of page is also very slow.
Can you help me in improving the performance of the page.
Thanks in advance.Hi
Firstly identify it is a issue with the BAPI side or not. Test the BAPI in R/3 side. If it takes too long, then tune the ABAP code. If it is fine, then try using cache settings at Iview level.
Regards,
Murali. -
Flash player loading files very slow and getting stuck after 100%
Hello all,
I have an issue with my development and need your help and feedback for the same:
I have developed various E-Learning courses which was published some in Flash Player 9 and some with version 10. Since Flash Player 10.1 was introduced all my developed courses was running fine. But it's found that user who are using Flash Player 10.1.85.3 is facing issue with file loading and playing the courses. Some time Flash player fails to load the chapters and files after preloading 100%, and sometime it's very slow in loading performance. I like to intimate that all these was not happening with Flash player version 10. Please give me any idea where I am going wrong. Is this kind of issue possible? If anyone faced the same experience. Please give me your valuable feedback.
Please Note: I have faced an scenario that, suppose a user is stuck with loading the course, and after getting stuck he clear his browser cache, and immediately after that the same player start working fine. And loading the course chapter properly. Need help to get rid of this kind of situation.
Thank you

I've published my site, but the videos take entirely too long to load. It takes more than twenty minutes for a two minute video to play. There is only one video per page. I don't know if this can be fixed, but I desperately need for it to. With loading time this slow, the site is rendered useless. Thanks in advance for your help.
http://web.mac.com/kristy_farisI use iSquint to compress the video. Have a look at this site to see my dv project that was 286mb original size, compressed down to 4.8mb. http://web.mac.com/lfairlie/iWeb/Site%204/Welcome.html
You can play with the size it compresses to quality wise as well.

Hi,after a migration from Version 5 to 6.5 the dataload becomes very slow.With V5 the dataload takes 1 hour, with 6.5 it takes about 3 hours.the calculation takes the same time.Any idea?
To many sub VIs could not be found so I can not give you more than some advises. But I see that you run all your loops at full speed. I do not think it is very wise. Insert the "wait (ms)" functions in all while loops, but not the loops handling the daq functions. Since they are controlled by a occurrence. In Loops handling user input only you may set the wait time as high as 500ms. In more important loops use shorter time.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

I've just converted a couple of 6i client server forms to 10g.
I'm using the Developer suite 10gR2, with its own built-in oc4j server.
It all works fine, after some fiddling to get icons loaded etc.
But the form is 10 times slower than in client-server. This is a total show-stopper for us. A form that took 2-3 seconds to load before can now take nearly a minute to come up.
Even our very simple login form is slow, many seconds instead of a fraction of a second.
I've tested on the workstation thats running the OC4J, This is a Dual-Xeon 2.4Ghz with 2G of memory, so its NOT the hardware. Its running XP-Pro.
Then I tested on a workstation, using a dummy html page to launch Jinitiator and get the form up. JInitiator installed itself perfectly, but erformance is exactly the same even though its a P-III-800 with only 256M of memory.
The strange thing that we notice is that the performance monitor on the oc4j server machine shows it as almost idle (3% cpu, almost no network traffic and idle disk).
But on the workstation the cpu is at 80-90% all the time, even when the form is just sat there waiting for user input!
So we think we have some sort of applet mismatch or configuration problem. Is there a newer (or older?) applet version thats quicker, or doesn't nail the cpu this way?
My next step is to download just the forms-and-reports services for linux and put that up on a second identical box that has Redhat-ES.
Has anyone else seen this sort of applet behaviour? if so any suggestions would be a great help because we're stumped at the moment.Good feedback folks, but I still don't see any explanations of whats happening, or why it should be slow.
I'll agree that putting the icons in a single file, one jar archive per form, is definitely more efficient. Putting all your icons in one file strikes me as silly since then you have to download all the icons, even if you never bring up forms that use some of them.
BUT gentlemen, it does not explain why we had the problem I described. I see no reason to suspect that the jar file would fix my problem, (of course I'll try anyway).
The point here is that the form was slow to start, OK, maybe that was because it was individually fetching 15 or 20 icon files.
BUT WHY SHOULD IT THEN BE SLOW AFTER THAT!
Sorry to shout but no-one seems to be hearing what I'm saying here:
1) the applet has the CPU locked-up at over 90% all the time
2) the cpu is at 90% when the form is idle waiting for input.
3) the form has completed painting the user interface just fine, I can see everying,
including all the icons, it all works right, its just slow.
4) its not surprising that its slow since the applet has the cpu pegged
5) we get the same pattern of behaviour on a form that has exactly one icon,
for a download of one file, a total of 232 bytes.
Now there is no way you can claim that a jar archive is significantly faster
than a single gif file download, they are both cached and the sizes are both so small that any difference is insignificant.
It looks to me like a bug in the applet, or some sort of configuration or set-up error on my part. But I can't find any documentation on how to control that. The applet itself appears to be very much a black-box with no visibility into whats going on inside it. No trace file, no log file, no debug options.
I mean debugging the applet itself here, not the form that the applet is presenting to the user.
I'm going to work on bringing it up on Linux today, for now I'll just run without icons while I get the forms/reports integration running. Then I'll come back to the icon issue next week. Maybe if I switch to jpegs the problem'll go away. SO I'll post a follow-up sometime next week.
