Loading times for images

Just a quick one on file sizes up download times.
When you do view an image preview, and it shows the filesize,
and a time @ 56kbps, is that the estimated time it takes to
download at 56kbps?
In which case, why does it quote 8 seconds for a 50k image,
or 30 seconds for a 200k image? Shouldn't a 50k image take about 1
second, and a 200k image take about 4 seconds?

Modems have been rated with 'baud' values ever since the
dinosaurs. "Baud"
means bits per second. It was quite 'modern' when we dropped
the use of the
baud nomenclature and adopted the 'edgy' bits per second....

Optimization on Load Time (Large Images and Sounds)

Hi,
I have an all flash website that works by having each portion of it to load and unload in the center of a frame based off the navigation chosen. Load times on everything but one part of my site are ok.
The dimensions of the part inside the frame are 968x674. I know that's relatively large for a flash file, but that can't be changed at this point.
Within the page there are objects that come up when you find an item on the screen. Its a dialog box and it shows text, an image, and has a voice over that reads what the text says. After you're done looking at it, there is an x-button to dismiss the window. There are 15 of these and they are exported to the actionscript. I add them in the actionscript via addChild. I figured this is a huge spot that could be reconfigured, but I'm not sure if it would make much a difference.
The other huge thing is there is a ton on the screen. It starts you off in an environment, and when you click 3 different sections, it zooms into that portion allowing you to look for the items you're trying to find.
There is also a man that talks and animates in the beginning and at the end. We are planning on taking out the end part and putting a text box up.
Here is the website.. its a propane safety site for kids. I know its kind of a weird idea, but it works and people seem to like it.
www.propanekids.com
The two parts of the site we are trying to optimize is the main menu when you first are at the site, and the "Explore" section. (Just click on the cloud on the front page.
If someone could take the time to give me some new ideas of how I can get these loading times down, I would greatly appreciate it!
Thanks

Increase in Loading time for LV search in 2011

Initially when I loaded LV2011 my quick drop and the search took nearly 5 seconds but now it takes nearly 20 seconds to load so is there any reason for this kind of performance. Also I don't have anyother big software loaded or running in my PC. I have added few toolkits from VI package manager may be that is the reason?.
The best solution is the one you find it by yourself

RavensFan wrote:
In my message in the other thread, I commented that I thought 20 seconds wasn't all that long. But I thought you were commenting on the loading time for LabVIEW itself. That does seem like a long time for any of the internal LabVIEW dialogs to come up.
(Actually, I find several internal dialogs seem to take longer to load the first time then they should including the properties dialog. But not 20 seconds long.)
Hopefully, with this message thread in the LabVIEW forum, others can comment and offer suggestions on how to determine what the issue your having is.
Yes now I have plenty of toolkits ( Thanks for spotting me in the other thread )
Jeff you hit the bullseye. The loading was set as Load palette when needed.

DrawImage takes long time for images created with Photoshop

Hello,
I created a simple program to resize images using the drawImage method and it works very well for images except images which have either been created or modified with Photoshop 8.
The main block of my code is
public static BufferedImage scale( BufferedImage image,
                                      int targetWidth, int targetHeight) {
   int type = (image.getTransparency() == Transparency.OPAQUE) ?
                    BufferedImage.TYPE_INT_RGB :
                    BufferedImage.TYPE_INT_RGB;
   BufferedImage ret = (BufferedImage) image;
   BufferedImage temp = new BufferedImage(targetWidth, targetHeight, type);
   Graphics2D g2 = temp.createGraphics();
   g2.setRenderingHint
         RenderingHints.KEY_INTERPOLATION,
         RenderingHints.VALUE_INTERPOLATION_BICUBIC
   g2.drawImage(ret, 0, 0, targetWidth, targetHeight, null);
   g2.dispose();
   ret = temp;
   return ret;
}The program is a little longer, but this is the gist of it.
When I run a jpg through this program (without Photoshop modifications) , I get the following trace results (when I trace each line of the code) telling me how long each step took in milliseconds:
Temp BufferedImage: 16
createGraphics: 78
drawimage: 31
dispose: 0
However, the same image saved in Photoshop (no modifications except saving in Photohop ) gave me the following results:
Temp BufferedImage: 16
createGraphics: 78
drawimage: 27250
dispose: 0
The difference is shocking. It took the drawImage process 27 seconds to resize the file in comparison to 0.78 seconds!
My questions:
1. Why does it take so much longer for the drawImage to process the file when the file is saved in Photoshop?
2. Are there any code improvements which will speed up the image drawing?
Thanks for your help,
-Rogier

You saved the file in PNG format. The default PNGImagReader in core java has a habit of occasionally returning TYPE_CUSTOM buffered images. Photoshop 8 probably saves the png file in such a way that TYPE_CUSTOM pops up more.
And when you draw a TYPE_CUSTOM buffered image onto a graphics context it almost always takes an unbearably long time.
So a quick fix would be to load the file with the Toolkit instead, and then scale that image.
Image img = Toolkit.getDefaultToolkit().createImage(/*the file*/);
new ImageIcon(img);
//send off image to be scaled A more elaborate fix involves specifying your own type of BufferedImage you want the PNGImageReader to use
ImageInputStream in = ImageIO.createImageInputStream(/*file*/);
ImageReader reader = ImageIO.getImageReaders(in).next();
reader.setInput(in,true,true);
ImageTypeSpecifier sourceImageType = reader.getImageTypes(0).next();
ImageReadParam readParam = reader.getDefaultReadParam();
//to implement
configureReadParam(sourceImageType, readParam);
BufferedImage img = reader.read(0,readParam);
//clean up
reader.dispose();
in.close(); The thing that needs to be implemented is the method I called configureReadParam. In this method you would check the color space, color model, and BufferedImage type of the supplied ImageTypeSpecifier and set a new ImageTypeSpecifier if need be. The method would essentially boil down to a series of if statements
1) If the image type specifier already uses a non-custom BufferedImage, then all is well and we don't need to do anything to the readParam
2) If the ColorSpace is gray then we create a new ImageTypeSpecifier based on a TYPE_BYTE_GRAY BufferedImage.
3) If the ColorSpace is gray, but the color model includes alpha, then we need to do the above and also call seSourceBands on the readParam to discard the alpha channel.
3) If the ColorSpace is RGB and the color model includes alpha, then we create a new ImageTypeSpecifier based on an ARGB BufferedImage.
4) If the ColorSpace if RGB and the color model doesn't include alpha, then we create a new ImageTypeSpecifier based on TYPE_3BYTE_BGR
5) If the ColorSpace is not Gray or RGB, then we do nothing to the readParam and ColorConvertOp the resulting image to an RGB image.
If this looks absolutely daunting to you, then go with the Toolkit approach mentioned first.

Issues with site load time. (bg images)

Hey, guys.
Having an issue with a site uploaded with MUSE. None of the images are overly large, but the load time is 5 to 6 seconds where it should be instant.
Looking at it, it appears as though all of the images are attempting to load simotaneously in one large chunk rather than in a line. Is there anyway to remedy this?

This isn't related to background images. It's how Muse is handling the loading of the ~100 images in the slideshow. Thanks for pointing this out. Until we have altered the loading method for these images, the only workaround I have is to decrease the number of images in the slideshow.

Slow load times for itunes u

We have noticed that lately iTunes U for UW-Whitewater (uww.edu) has been extremely slow, and sometimes even timing out. We have been trying this from various different locations and computers. It appears to be something on the apple side. Has anyone else seen this?
Apple Engineers: Any updates as to what might be going on?

Greetings Guys;
We had the same issue yesterday, but the issue seemed to be affecting only the iTunes desktop application. When I would preview using the iPad, load times were normal. The issue seems to have been resolved this morning.

How to decrease loading time for 0Mat_Plant

Hi Experts,
I am currently looking to decrease loading time of 0Mat_Plant. I have gone thru performance material available and checked following things listed below :
Plz note following:
1) Standard delta is avail but it has been enhanced and there are Z fields. So if i use delta, them I might be missing delta for Field.
2)Can we switch OFF number range SID buffering to avoid memory allocation on daily basis ...somehow through ABAP program?
3) BUffering can be switched OFF, but there is delta load also alonwith full load. So performance would decrease for delta records. But no of records for Full load is 188000 and for delta is just 1700 around. SO will this helps in decreasing overall time? Any idea?
Load is taking around 90 minutes in my system (Full Load)..
I m not clear abt data package size and if it will help me or not..
What more can we do??
Any help would be appreciated and points would be assigned......
Thanks in advance

Hi Nagesh,
Here are my replies;
1) Loading time is only for 0mat_plant..
2) R/3 job finishes quickly....no prob seems to be with this..
3) I m not clear about "locked trfc..but there are no errors in trfc...and there doe snot seem to be IDOC clogging problem...
4) Not sure what yu mean by trfc "released"....
I checked R/3 JOb log and its pasted below ( though for other datasouce)....
I want to know wht does it implies.....in general i hve few questions listed below after the log..::

I want to confrm my understanding abt extraction process when infopackage gets triggerred...
Infopackge gets triggered....->R/3 job gets created/triggered....-> Info iDoc regarding request sent to BW..-> Application document(??)) posted..(( posted to what???.... passed to Trfc??....and then to psa which is seen in monitor??))...
Like wise after successfull passing of datapackage to BW ( not posting to pSA) , next datapackage is sent..... and so on...
What is TRfc?? .as far I know its function modules created to pass data to bW thru RFC call...(??)...
IF you can give me clear picture of whts happening behind the scenes, it would be great.. or helpful links would do....it would be help me to enjoy wht you ae saying and how to tune more...
THanks for your patience and help...
Already assigned points to you..
PS: I hve turned OFF buffering for master data records greater than 100, 000 and saved approx 25% for each master data records....

Load Time for executable

Hi,
I've just built an exe from a vi that loads very quickly. It takes about 10s to display the icon in the task bar and then more than 40s to display the front face.
I've disabled everything in my vi so that the only thing made at start up is an apparition of the front face from 100% transparancy to 0%. In the exe i just include my vi.
Do you have an idea to fix this?

Remi
Here are attached the CPU charge of the vi itself and the vi in exe. I've checked the while loop and added some timings which improves a lot the load time of the vi and a little the load time of the exe.
I don't use high resolution images on the front panel.
I'm using Labview 8.5 under windows XP SP3. I don't know exactly the version of the driver installed (I couldn't find).
The application is acquiring data on a RFID system and after some analysis fills a database. In the meantime, a bigger part of the database is read and displayed on the main front panel.
It has been designed by launching 6 times the same acquisition vi (which is composed of 2 loops one generating data and one consumming datas) in order to try to rich real time treatment.
Best regards,
Julien

Load time for a 1hr m2v and wav timeline

Hardware: Intel P4 3.2ghz, 3GB ram, Nvidia FX 5700, Asus P4C800 mobo, m-audio delta-66 sound
I'm experiencing a lengthy wait time to load a 1hr video and sound track as timeline. It has been loading for over 25 minutes now and thelittle splash screen reports over an hour to go... as I write this note.
I'm curious if that is about normal an this kind of hardware? I ask because I loaded the same video and sound file into DVD architect in less than a minute. and I've had really bad trouble with Encore CS4 crashing repeatedly. Or locking up and having to be killed.
I moved the whole shooting match to a different machine and am able to at least run Encore, but wondered if the lengthy load time is a signe of trouble on this machine too.
Oh, and nothing else going on while the video is loading... (just normal stuff running as always)

2 Sata 200 GB No partitions
All are 7200 rpm (or whatever the 7200 stands for)
The work is located on 1st sata drive (E)
Common stuff for the hardware its on. Also I recall loading stuff in `the blink of an eye' when I was using CS2 Encore (On this same machine, but no longer no installed)
I see a monster thread here about Nvidia cards and Encore crashing. I do have an Nvidia FX 5700 as mentioned earlier, and it has the latest drivers available at nvidia site.
Also I have hardware acceleration set at 50 percent... Encore will not run with it set 100 percent.
Acceration itself should not come into play when importing right?

Long loading times for Safari on iPad Air with iOS8

I've had long loading times in Safari sInce upgrading to iOS8 on my iPad Air 128 GB. Are any of you having the same experience?

Sometimes I question myself, how come that iOS being held in beta for over quarter or even over a half a year, and most certainly long enough in alpha, still comes out so much raw and buggy every release? Sometimes it feels like it's only getting worse concerning the debugging.
I wanted to address the HR manager of the Apple Inc. to query him/her about HIS/HER dedication to the overall work being done. Why, the ****, does Safari get slow, why, the ****, is it unpredictable to define whether a sound stream in Safari's tab will end upon tab closure or not. Morever, why do iPhone iMessages fail to mark a message or a chain as a read one even thought you just really did it. Beyond that miriad of similar questions I have just another three, since when is it official Apple support position to advise you to wipe out your device and install everything back from iTunes, not the cloud? But what is more important, how come that support representative tells you first to back up your buggy iPad, wipe it out and restore from that backup both with iTunes? Finally, we all know how Apple does cherish it's developers, can somebody tell me how, for heavens sake, this website ever possible to exist then — Texts From Xcode?
I don't want neither need to mention that switching between tabs in iOS7 (I have had no chance to test it in iOS8) in Safari never gave you any sure answer whether your tab will be reloaded when you get back or not: whether have you copy any post before leaving, to paste back on return or not.
After all I do still love Apple, I do love people's ideas. I do love the overall outcome, but I want to tell Mr. Cook one phrase I heard when I used to be a head of a department in a medium size company and had to deal with continuous fails of the personnel and most often ended up doing much things myself, it was not the exact situation as with Apple although I hope you can trace a path: If a manager has to do anything besides managing he or she failed to manage one major issue — the personnel one.

Slow loading time for text

The website is published, and was working fine. Now when I go to the website homepage > projects > enclosed retail (or any of those project pages) , the text that is supposed to show under the images isn't loading. If I move the mouse around over where the text should be (underneath the image), it reappears, but otherwise stays hidden. How do I get the text to load with the images?

Chrome version 33 broke the loading of web fonts (for most websites that use webfonts, not just Muse sites). The symptom of the bug is that some combination of the webfonts used on a page fail to draw on the first paint of the page. Refreshing the page or interacting with it such that items are re-painted by Chrome causes the undrawn text to appear.
Google is very aware of the bug. The Google bug report is here <https://code.google.com/p/chromium/issues/detail?id=336476&q=font&colspec=ID%20Pri%20M%20I teration%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified>. From the notes in the bug it appears they're considering folding a fix from their development branch back into 33, presumably so they can do an update prior to their normally scheduled 34 release.

Extremely long load times for Cisco's WEBEX.

My company attends numerous meetings with our customers/suppliers and WEBEX is giving me headaches. 5-15 minute load times. Conference room PC is running win7 and I've tried both google chrome's webex app and just running webex from IE to no avail. These connections do go through eventually but I'm constantly hounded about why they are taking so long and I don't know why. Have any of you experienced this or have any clue as to a possible root cause?

Slow load time for Quick Time in Mail

Does anyone know why when you receive a video file (like WMV) in Mail that Quick Time takes so long to load it? It did not use to take so long before Snow Leopard. If you click on play before it is loaded, you get audio only. Are there any work arounds or something other than Quick Time that can be used?

From Adobe Support: 17 secs response time is a normal time interval for the "Print Settings" dialogue.

Very Slow Load Times for PDF Document

Hi,
I have a PDF document that takes forever to load in preview (on the order of a minute or more). It is eight pages, but when I try to go to the last two pages, each of which has a drawing created by using Autoshapes in Microsoft Word, again they take a minute or more to load.
The document looks to have been created by Acrobat 6 for Windows from a MS Word document. Adobe Reader 7.0.7 on another machine loads the document correctly and speedily (well, as speedily as Adobe Reader can...).
Are there known problems with this type of graphics, MS Word drawings, in a PDF document? Is there any way I can make the document load faster?
Thanks,
Jeff Corbets
