Do JavaFX applets tend to download faster than Swing applets?

Historically, the biggest concern with Java applets is that they take too long to download.
Is it true that JavaFX applets will download faster?
In particular, by using CSS properties instead of all the Swing method calls, will JavaFX applets tend to be smaller and download faster (since the browser, not the bytecode, will do the work of translating the CSS code to graphics commands that the operating system can understand)?
Thanks,
John

I do not think size is the main issue for startup.
It is only applicable to cold start (i.e. first launch) as on subsequent launches jars will be coming from cache.
And it does not impact much "perceived" startup as typically application can appear to be "live" earlier than it is fully loaded
(e.g. using preloaders).
For the warm start scenario it is still the same plugin but
a) JavaFX applications are by default deployed in a way to minimize number of network connections
b) JavaFX toolkit is initialized instead of AWT/Swing
This gives JavaFX fundamental benefit over "Swing applet" scenario but ...
a) it does not magically make it instant as jvm still need to be started, etc.
(if your application is slow to start as standalone it will not be starting instantly in the browser)
b) JavaFX runtime and Java deployment code may have bugs that lead to suboptimal performance
Best is to give it its own try and see if it is fast enough for you.

Downloading faster than restoring :S

Hi there again,
I just figured out that I'm actually downloading faster than restoring up :s
Picture this:
I have a internet connection of 20mbit, my average download speed is around 19mbps I can download around 6/7Gb a hour.
At the moment I'm restoring a map with high-res RAW images (16MB each). the map is 5,5Gb large and the estimating time is 4 hours.. This means that the restore speed is around 13mbit / h. How is this possible?
And the fun part: I can download while I'm restoring and it doesn't effect my download/restore speed???? Connected with a wire to timecapsule 500gb.
Hope someone can clear me out.. I can't figure it out...

Mac's can be faster than PC's and PC's can be faster than Mac's.
It all depends upon the processors, graphics capability and other factors, age of each machine, data on the drive, etc.
If you put Windows and OS X on the very same type hardware, freshly installed on each hard drive, everything matches. Likely OS X would be a hair slower than Windows.
It's because OS X renders the UI with a finer degree of detail.
However when it comes to hardware, PC's outstrip Mac's in that department not mainly in the processors, which they both share the same Intel ones (Mac's sometimes gets theirs before PC users) but rather the video card upgrade choices and tweaking ability Windows towers users enjoy and Mac owners do not.
http://www.cbscores.com/index.php?sort=ogl&order=desc
So if your considering a 3D gaming machine, your choices are simply a Win 7 tower.
Generic PC's also have another advantage, one can replace Windows with the lighter Linux, I've done that with HP XP netbooks that were going for a song, slapped Linux on them and they make great portable use machines for the basics. I even use a UI that looks like OS X so I feel at home.

Why is my MacBook downloading faster than my new Imac?

I have a two year old Macbook; 2.4 GHz Intel Core 2 Duo, 2GB 667 MHz DDR2 SDRAM with about 30GB left of memory. I also just purchased, from apple, a 27" Imac; 2.8 GHz Intel Core i7 with 4 GB 1067 MHz DDR3. and have just under 850GB left. The Macbook is running on 10.5.8 and the Imac is on 10.6.3.
My issue is that when i download/stream video to my Imac it takes a substantial amount of time. I love to watch movies, tv shows, ect, on my Imac. I was disappointed by how slow the downloads would take. So I set up my macbook right in front of the Imac to compare the speeds. I went to the Movie Trailers section on apple.com and I clicked on The Last Airbender 1080p (149MB) at the same time for both computers (on WiFi of the same network). My macbook finished the download 5 minutes faster than the Imac. I then tried the 42MB version with a minute difference with the Macbook. I then went to youtube and it was almost the same speed. I tried Itunes and it was about the same speed as well. I then did an internet speed test with both and got these results:
Macbook: Download 18.45Mb/s, Upload 2.28Mb/s, Ping 93
IMac: Download 20.88Mb/s, Upload 2.3Mb/s, Ping 89
I don't know if any of this information helps or if anyone will even read this far but the apple store is extremely far from my house and would try almost anything to fix this issue. My questions are:
1) Is this a known issue that has a fix, if so how do i fix it?
2) Is this possibly a faulty computer that i would have to return?
3) Is this the way it's supposed to operate and if I don't like it take it back
Thanks in advance for anyone who even reads this post.

You may also want to check your router. Some routers use a priority bandwidth feature that will dedicate more bandwidth to one machine. If for some reason the macbook's download was started earlier than the imac's, then this might be part of the discrepancy. There are a lot of factors to think about when it comes to wifi bandwidth.
I do agree with the one comment about testing one computer at a time instead of simultaneously.
Also, when you said you have the movies from the Macbook on your iMac, can you elaborate? If you are using a shared library, then your iMac is going to be using part of your download speed for updates to your shared itunes library, where your Macbook is only going to be uploading the list. If I am incorrect in my understanding of the sharing of iTunes library, someone please let me know.

Swing applet looks different in browser than in applet viewer

I'm developing an applet using Net Beans 5.0. When I run the applet in the applet viewer I get a totally different look and feel than when I run the applet in a web broser. The background colors are different, the buttons are a totally different style and color, and some buttons that show up essentially transparent in the applet viewer are totally opaque in the browser.
The applet viewer is the one that looks like the interface that I designed in the Net Beans GUI builder, so can anyone tell me how I make it look the same in a Web Browser?

It looks like you're right, so how do I ensure that
my applet will look the same on different versions of
JVM? There's got to be a way, right??yes. you should look into javas pluggable look and feel system.
the cross-platform (java) look and feel changed dramatically between versions 1.3, 1.4, and 1.5.
however, if you use another look and feel, such as motif, or perhaps your system's look and feel (windows, mac, etc), the program should look pretty much the same (perhaps a little different, but not like the differences in the Java look and feel).
if you want to be COMPLETELY sure that they will always look the same, select a third party look and feel that comes packaged in a jar file that you are free to distribute with your applet.
Some good third party look and feels are JGoodies Plastic, and Incors Alloy. And there are others.
if you use one of those, it should look pretty well the same on all platforms, and in all JVM's.

Why AWT apps are faster than Swing apps?

I have written applications using both AWT and Swing. While running under Windows, I feel that AWT apps are much faster and smoother. In contrast, Swing apps fare terribly. Regardless, I can not go back to AWT because of thier limited capabilities.
I love Java APIs, it is great for programmer. But what about the consumers? Consumers do not care whether it is written in Java or Visual C++?
I am having a mid-"programming" crisis. I do not want to but, but would be forced to use VC++ for desktop apps abandoning Java.
I would like to know if you are a serious desktop programmers, what is your motivation for using Java, not VC++ or something?
Thanks.

well, for me, it's that one it's Platform Independent. and that does come in handy when your work uses macs instead of normal PCs. Second, it's free to use, unlike VC++ and Pseudo Code (Visual Basic), you don't have to pay unbeleivably large sums of money to get a good compiler. And then there's the whole "Swings Apps are Slower", yes they are, however, if you program them write, they only take a while to initialize, once that is done they run as fast as any Native Program unless you have a tremendous amount of calculations and dynamic generation of components. And also the no Excecutables, true, and... not true, creating a Jar File is almost the same as making a making an EXE, only Jar Files are... platform independent.... and unlike C++ which gives you enough rope to run around the world three times, jump over the moon and hang yourself for actually using it, Java is a clean programming language, not a whole lot of those nasty characters and styles that ugly up your code. at least these are the reasons why i pick Java as the language to come out on top of all others.

Swing Applet using JSObject.getWindow can not use javaFX

I have a Swing Applet that I will like to extend with some javaFX 2.0.3 abilities.
The Swing Applet uses the JSObject.getWindow method which is part of plugin.jar.
When I add javaFX I am not able to compile my application as jfxrt.jar also has a JSObject implementation, but without the getWindow method.
Is there any way I can extend my existing applet with javaFX?

The order of dependencies is probably not the issue here but rather that there are two classes with the same fully qualified name which causes problems if the signatures differ

The video sound faster than video ipad mini, this happen when I download the iOS 7.1 to my iPad mini, how can I fix that?

The video sound faster than video ipad mini, this happen when I download the iOS 7.1 to my iPad mini, how can I fix that? Or just wait till Mac release a new version update, also some game and apps doesn't open or when open they close, please help!!!

Start by closing all apps and resetting your iPad and see if that helps with any of your issues.
To close an app, drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it. Close all of the apps on the iPad this way.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Very slow network performance - with uploads faster than downloads

I just got new ISP - 100 mbps through a Cat5 line. It checks out when I run ethernet directly to a computer. However, I want a totally wireless network.
I have a Time Capsule attached by ethernet and that is my main network device. I also have two airport Xpress' to extend the network.
I am getting, on average, 16 mbps! And, upload speed is generally higher.
The Time Capsule is about 2 yrs old, but it is an "n" device.
Anybody have any idea what the problem might be? I was considering getting a new extreme and using the Time Capsule as an extender instead of the expresses because, as I understand it, the express has one band only. Would that be better? Mainly, I want to get the speed up to what it should be.
Is there some way to trouble shoot the Time Capsule?
Others in my building with D Link or Linksys routers are getting over 80 mbps wirelessly, so I know it is possible.
Any help would be greatly appreciated. I want to stay with Apple products, but if not possible I will get another brand of router.
Thanks,
Deanna

So, William, I got an Airport Extreme. Within 20 or so feet of it I am now getting 85 to 95 Mbps!
Great!
However, in the far reaches of the house, signal is low and I have not been able to extent network with either the Time Capsule or an Airport Express. They just won't connect.
Based on the earlier numbers you gave me, you won't be able to establish a reliable connection "in the far reaches of the house", as it's too far away from the base router. You'll either have to (1) run Ethernet to that remote unit, (2) use PowerLine units as an Ethernet extender, or (3) put the remote unit closer to the base unit.
I reset the Time Capsule a couple of times. I noticed that both devices are automatically set to channel 157.
That's a 5 GHz channel. That band can give faster throughput, but the signal strength falls off faster than in the 2.4 GHz band.
The Extreme has 2 channels - 2 and 157. I do not have the option of changing the channel on either of the other devices.
That makes sense, if they're configured to extend an existing network. They must communicate on the same channel as the base station they're extending.

How can I get tracks to play faster than normal speed in itunes?

I have lectures, audio books, and other recordings that I would like to play at faster than normal speed (like 1.5X or 2X normal speed).   I've set all of these recordings as audio books because I read that they have the option to play faster, but, I can't find how to actually make them play faster. I also read that it's possible to open them in quicktime, but that is very much less than ideal and a waste of time. Surely there is a way to do this in itunes, but I can't figure it out.
Thanks for any help.

I will show you how I played my audio or mp3 files at any particular speed. This method will allow you to simply enter in your desired speed.(ex. 1.5 or 1.33)
In my case Im using an audio book [Lord of the flies] I download off youtube as a MP3 file using this program:
http://download.cnet.com/MediaHuman-YouTube-to-MP3-Converter/3000-2140_4-7544580 3.html
      First off, you will need to make sure your audio file is open in QuickTime player rather then iTunes. First you need to locate the audio file. If your audio file is in itunes then right click the file and select "Show in Finder"
     The file should open in a finder window, highlighted. Right click the file, go to "Open With.." And click Quicktime Player. (If quickTime Player is not an option, you need to go to "Other..." and select QuickTime Player from your Applications folder)
Now that your mp3 file is open in a QuickTime window you may proceed to step 1.
1) Open Finder
2) Click Applications
3) Click Utilities
4) Open AppleScript Editor
5) In the program copy and paste the script below.
6) Click "Compile"
7) Now to test this script, click "Run" A window should pop up prompting you to enter your desired speed (default is 1.5)
8) press "OK" and quick time should start playing your audio at the speed you entered in.
9) If you would like to use this script again, go to File > Save... >Name your AppleScript and save it Anywhere (I saved mine in the Music Folder for easy access)
tell application "iTunes"
pause
set myTrack to location of current track
# the player’s position within the currently playing track in seconds
set mySeconds to player position
end tell
# show a Dialog
set SpeedFactor to 1.5
display dialog "Enter speed factor:" default answer SpeedFactor
set SpeedFactor to text returned of the result
tell application "QuickTime Player"
activate
# pause all previously opened documents
set open_docs to documents
repeat with doc in open_docs
pause doc
end repeat
# open the track just played in iTunes
open myTrack
# get the 'QuickTime' document, MyTrack should be equivalent but it isn't
set MyMovie to first document
# rewind by 10 seconds
if mySeconds > 10 then
set mySeconds to mySeconds - 10
end if
# set current time
set current time of MyMovie to mySeconds
# set Speed Factor and start playing
set rate of MyMovie to SpeedFactor
end tell

Why is iMovie 5 x faster than AP3?

I noticed that slideshow exports in AP3 seemed to take a long time and did a test with iMoive 09. I exported the exact same slideshow of 60 pictures and 1 song from both iMoive and AP3. The iMovie export was 5 times faster than the AP3 export.
Why is this and can anything be done to speedup AP3 slideshow exports?
I have a fairly quick Mac, 2 x 2.26 Ghz Quad-Core Intel Xeon, 16 meg of ram, ATI Radeon HD 4870.
Any thoughts?

I read on the website that the update 4.0 was supposed to work faster than the last but I that since I updated (2 days ago) my work in firefox has become quite sluggish. Any suggestions?

Hi there. I upgraded to firefox 4 on Monday (two days ago) since I saw that the new version was supposed to run faster than firefox 3 that I was using. However, since I've started using it, I wait longer for a page to download than I had to before and the whole browser just is sluggish to respond. Any suggestions?

Sounds like it either believes that there are headphones plugged in, or the switch is broken.
Why in the world would you take it to Best Buy for service? Take it to an Apple Store. They can replace it on the spot if it's defective.

Is DVD Studio Pro faster than iDVD?

Sorry I'm double posting this but I didn't get my question in the Subject line. Is DVDSP faster than iDVD? If so, by how much? I'm on the endless quest for more speed.

I have a feeling you're asking about the time to compress video, in which case it will depend on the settings you've chosen. As a rough guestimate I would say that iDVD will compress as fast as the faster possibilities in DVD Studio Pro (which is using Compressor behind the scenes). Using Compressor would allow you to more carefully get the best quality for a given amount of video, instead of iDVD's one hour or two hour approach.
Usually though you would tend to compress the video before taking it into DVD Studio Pro, and you wouldn't need to compress it again before doing a build or burning a disc.
If you meant is DVD Studio Pro faster to create a title, it varies depending on what the disc needs to do. The important thing is that there are things you just cannot do in iDVD, and if you need to do those you could use DVD Studio Pro to do them.

Netscape is faster than Safari uploading pages to busy site.

Netscape 7 is MUCH faster than Safari uploading pages to an interactive web site that has a lot of traffic. Several times using Safari to upload after filling out forms or doing other things, I've gotten impatient, switched to Netscape 7.02, did the same form or interaction, and sent the page. Netscape hangs much less time before the confirmation downloads to my browser. I've gotten confirmation via Netscape while Safari is still hanging, even though I tried to upload via Safari several minutes before I switched to Netscape. This has happened at NYTimes.com and other busy web sites.

Greetings,
The reasons behind your experience could be many, but try this to see if it improves things:
Quit Safari if it's running and open System Preferences>Network.
In the DNS Server tab, make sure IPv6 is turned off, and enter these two DNS servers to replace the ones you currently have:
208.67.222.222
208.67.220.220
click Apply Now and quit System Preferences.
Next, do these things in order:
1. Go to Home/Library/Cookies and delete the Cookies.plist file.
2. Go to Home/Library/Caches/com.apple.Safari and delete the contents of that folder.
3. Go to Home/Library/Caches/com.apple.Safari/Web Page Previews and delete the contents of that folder.
4. If you don't want to use the Top Sites feature, open Terminal and paste in this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2
5. Go to Home/Library/Caches/Metadata/Safari and delete the contents of that folder.
6. Go to Home/Library/Caches/Safari and delete the contents of that folder.
7. Go to Home/Library/Safari and delete these files (if you have them):
Downloads.plist
History.plist
Form Values
LastSession.plist
WebpageIcons.db
Repair Disk Permissions, then restart Safari and see if the speed is improved.
