Displaying photos in servlet speed issue

Hi,
I am accessing images from an external drive outside of the tomcat directories? The problem is that if i have a report with 30 photos it is taking about 30 seconds to load, and there could be reports with up to 100 photos at any time. I am currently using a BufferedInputStream and a BufferedOutputStream but it is still too slow.
Thanks

How big are they each? What's the complete file size? What's the harddisk speed? What's the interface of the external drive? What's the memory size? What's the network speed?
One (raw) photo can quickly be 1MB. Downloding 1MB over a 1Mbit line can last 10 seconds (at it's best, generally it's a bit slower). Then I'am not talking about the hardisk speed/interface and the efficiency of the code.

Speed Issues

Greetings and Salutations,
I'm having speed issues with my Adobe AIR application. From what I've read on the web, AIR is supposed to be fast at drawing graphics. I am writing an application which has multiple screens. On one of the screens I have a tab (SuperNavigator) which has a canvas on it. That canvas has a series of other canvases (built with a repeater) that have graphics in them. I am having speed issues when I have more than 50 of these children canvases. I've tried running it without the graphics (code below is without the graphics) to see how it performs. When I have 954 of these canvases being drawn it takes about 2.5 minutes to draw. This is unacceptable and I'm wondering if this is something I've induced or if AIR was never meant to handle such a large amount of canvases (actually this isn't a large amount, in a real world environment there could be a lot more). I've included relevant clips from the code. There are a couple empty boxes that in the real application will hold graphics.
The class withing the Tab Navigator is a canvas.
In the action Script (the setter line takes 2.5 minutes to get past) (it's binding to the repeater that seems to be my problem).

The Canvas is a very heavy object that has lots of overhead. Even worse is the VBox object that is in there multiple times.
What exactally are you trying to accomplish? Just looking over the code, it seems that the same could be done directly with the Graphics API, at a much faster rate.
For each of the VBoxes and Canvases you have, the entire size of each child and parent need to be re-evalulated each time you add or change something. This is a HUGE overhead, and probably why the app is running so slow. You may need to convert this app to use simpler objects (UIComponent or something lower-level like that) to get any speed.
Are you using Flex Bulder? Take a look at the app while the Profiler is running to see what I'm talking about.

A few questions re displaying photos (Am I missing something?)

I am a Windows XP user with a brand new AppleTV. I'm generally happy with it but am not impressed with the way it handles photos. Am I mistaken or is there no way to do the following?
- View subfolders of photos individually (it would seem not, based on others posts here.)
- View a slideshow that spans more than one folder.
- Set up a selective slideshow in advance (like a music playlist.)
- View thumbnails of the images in a folder, and go directly to the one I want to see.
- Jump ahead several photos in a folder instead of having to page through every single one.
- Zoom in on a portion of a photo that I have paused.
- Browse photos from the hard disk without syncing them.
- View photos by metada (EXIF tags, maybe.)
I know some of the above are a bit of a stretch, but others seem pretty straightforward. Is it really so hard to display a page of thumbnails? My cheap digital camera does it when I hook it up to my TV. Am I missing some way to do any of the above? What are the odds Apple will enable them in a future update? Thanks.

I totally agree with regard to the Auto/Advanced modes. Maybe the entire idea of streaming/browsing photos from the HD could be buried in the Advanced mode and hence never be an issue for those who want to retain the interface's initial simplicity.
It seems like looping could be added so easily. I used to keep my photos in folders arranged by year (2008), containing subfolders of months (2008_01, 2008_02, etc.) which in turned contained subfolders for each day (20080101, 20080102, etc.) I wanted to be able to view each day's folder individually through AppleTV, so I have moved all the individual "daily" folders into the My Photos root level. This is all well and good (except that scrolling through that many folders is a little clunky*), but it also means that no slideshow can display photos from more than a single day. Adding one option -- "Slideshows span folders: Yes/No" would solve that problem and make it much for flexible for me (and others, I presume.)
I know, I know, I am attempting to use the device for purposes for which it was not intended. Still, it's a fun little box, especially for the price (and who knew I'd get such a kick out of watching YouTube on my tv?)
On the other hand, whoever incorporated the 24-hour limitation for watching an entire rented movie must live in a household without little children around, but that's a subject for another thread.
*Here's a crazy idea: Maybe the basic "Auto" version of the AppleTV should remain exactly as it is, and the full-featured "Advanced" mode require the purchase of an optional advanced remote control that incorporates the famed iPod clickwheel for scrolling quickly through subfolders and/or very long lists of folders?

Front Row Does Not Display Photos After Updating to iLife '11

I just updated to iLife '11 and now Front Row shows only a black screen when it should display photos photos in landscape mode. The background music plays and photos in portrait mode are displayed correctly, but the ones in landscape mode are not shown. Everything seems to be fine in iPhoto '11. What should I do to fix this issue? Thanks.

Same for me on my Mac Mini: I can see the shared pictures but can't see the ones in the local library. Funny thing is that I can see that library from my other Mac.
Also I noticed that one picture appeared in the middle of the (empty) slideshow, only 1 of 67. In the list view, those pictures appear normally, as you can see in this screenshot http://d.pr/eiXB
I'm a first-time iLife user, so I don't know if the issue is '11-specific.

Will it display photos while watching for mail?

Will I be able to setup an ipod touch to display photos (one after the other, like a screen saver) and also in the background monitor for new mail and create a visual or audio alert when mail arrives? It would be connected to a wifi network of course...
Thanks for any info, as well as what applications might do this sort of thing.

I used to have this same issue, the problem was I had the incorrect incoming mail server port (it still worked but once I changed that port # never had the freeze up issue again).
Go into Settings-Mail-your account and see what incoming server port you have listed. Then call your email server and ask what the correct ports should be in both incoming and outgoing. Also ask if you should have SSL on or off, they should have a form already filled out for all of the correct settings to use their e mail with an iphone.
Also, you say you have powered off the iphone. Have you done a hard reset?
Hope this helps.

Speed Issues Fixed In 9.1.2

Lost all my thumbnails updating to iPhoto 9.1.2 but rebuilding the thumbnail database solved the problem. Best of all, the speed issues are finally gone in iPhoto 9.1.2. Opening the application is way faster again (2 seconds as opposed to 12 seconds or more). Scrolling is way faster again. Can't believe it took this long for Apple to fix this mess. Nevertheless, iPhoto '11 feels like iPhoto '09 once again. Thanks Apple.

Iteration Speed issue when Indexing 3D array wried to a while-loop

Brief Description of my Program:
I am working on the real-time signal generation by using LabView and DAQmx (PCI-6110 card). My vi reads the big data file (typically 8MB txt file containing about 400,000 samples (complex double precision). Then, the signal is pre-processed and I end up with a huge 3D array to feed while-loop (typically 3D array dimension is N x 7 x M where N & M >> 7). Inside the loop, that 3D array is indexed and processed before the results are written to the DAQmx outputs. I have a speed issue when indexing the large 3D array (i.e, 3D array having a large sub-array size). My while-loop could not run fast enough to top-up the DAQmx AO buffer (at the output rate of 96kHz). It could run faster only if I use smaller 3D array (i.e, smaller-sized sub-arrays). I do not quite understand why the size of 3D sub-array affects the rate of looping although I am indexing same sub-array size at each iteration. I really appreciate your comments, advices and helps.
I include my 3D array format as a picture below.
Question on LabView:
How does indexing an 3D array which wires to the while-loop affect the speed of the loop iteration? I found that large dimension of sub-arrays in the 3D array slows down the iteration speed by comparing to indexing the same size of sub-array from smaller-sized sub-arrays of the 3D array to perform signal processing inside the while-loop. Why? Is there any other way of designing LabView Program to improve speed of iteration?
attachment:

Thank you all for your prompt replies and your interests. I am sorry about my attachment. But, I have now attached a jpg format image file as you suggested.
I had read the few papers on large data handling such as "LabVIEW Performance and Memory Management". Thus, I had already tried to avoid making unnecessary copies of data and growing arrays in my while-loop. I am not an expert on LabView, so I am not sure if the issues I have are just LabView fundamental limitations or there are any other ways to improve the iteration speed without reducing the input file size and DAQ output rate.
As you request, I also attach my top-level vi showing essential sections such as while-loop and its indexing. The attached file is as an image jpg format because the actual vi including Sub-VIs are as big as 3MB in total. I hope my attachment would be useful for anyone who would like to reply my question. If anyone would like to see my whole vi & llb files, I would be interesting to send it to you by an e-mail privately and thus please provide your e-mail address.
The dimension of my 3D array is N x 7 x M (Page x Row x Column), where N represents number of pages in 3D array, and M represents the size of 1D array. The file I am currently using forms 3D array of N = 28, & M = 10,731. Refering to the top-level vi picture I attached, my while-loop indexes each page per iteration and wrap-around. The sub-VI called "channel" inside the while-loop will further index its input (2D array) into seven of 1D arrays for other signal processsing. The output from that "channel" sub-VI is the superposition of those seven arrays. I hope my explaination is clear.

Looking for iPad App for displaying photos via a projector

I'm looking for an App that will allow me to display photos using a projector yet permit manual advancing through the slides.
The included Photo app only works with the projector when in slideshow mode. As soon as I try to manually advance a photo the projector output stops.
I've seen references to Keynote but I'd rather not have to import 'x' number of photos into Keynote to be able to display them. I'm not convinced Keynote will do what I want anyway.
There's got to be an app out there somewhere that does this. Isn't there?
Thanks.

Locking the iPad so that a user can't exit an app isn't possible for any developer to implement, since the developer kit doesn't provide that sort of access to the low-level routines in iOS. The only way to lock into a single app is to use a case/frame that covers the Home button (and turn off the gesture support in the settings in iOS 5). A number of companies make kiosk mounts for this purpose.

HT204291 Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Here are the steps for AirPlay:
Before starting Azul from your (running iOS 5.x/6.x) home screen where have have all your apps we need to turn on mirroring
On your iPhone 4S/5 or iPad 2 or 3, double-click the Home Button to view your recently-used apps.
Swipe all the way to the right to until you see the icon.
Note: If the icon does not appear, go to the "If AirPlay Mirroring is not visible or available on your mobile iOS device" section.
Tap the icon to see the list of available AirPlay devices.
Enable AirPlay Mirroring in this menu by tapping on an available Apple TV, then sliding the Mirroring slider to ON.
Now you should be seeing your iPad/iPhone on your TV.
Start up Azul now and using the settings icon on the top right corner go to the option that say "TV out" ON.
When you do that you will see an Orange screen
Now click "Done" and play the video you want to watch and it will AirPlay

Home Hub 3 Speed Issue

Some 6 weeks ago I had an issue with losing my internet connection completly, and eventually after a long session with the help desk I magaged to reconnect using the direct port on the main phone socket. However since then I have had a speed issue and Ive been only getting speeds in the order of 2.3Mb.
However running the BT speed test tells me that the connection to my Home Hub 3 is running at 8.13Mb, but the connection to my computer is running at 2.18Mb.
I have tried every thing I can think of. Followed all the advice to improve the connection but nothing works. Reseting the Home Hub, reseting the factory defaults. I've closed down every program running in the background, disconnected the rest of the hardwired network, fitted a new shorter cat 6 cable. All to no avail. The speed still stays firmly at 2.18 to 2.15. down and 0.37 up.
Could their be a fault with my Home Hub?
Thaks for any advice.

Windows 7 64bit speed issues

Hi,
Our company have been purchasing iMacs for the past 4-5 years and installing Windows XP without any problems. Last year we started installing Windows 7 64 bit onto, the then current, leopard model without any issues.
We have recently purchased a whole batch of i5 iMacs with lion installed. I have installed Windows 7 64 bit without any problems but have started noticing huge slowdown with what seems to be hard drive access o every single machine. Even a single one we purchased when they first came out.
Using Perfmon I cant see any stress on the CPU, GFX card or RAM but there seems to be something odd with the hard drive access. I have stripped Windows 7 down to its bare minimum services removing Aero, themes, and all non essential services but still the speed issues occur.
I have messed around with the pagefile size, indexing, etc, but nothing is having any impact.
For example, when I save a simple spreadsheet the saving window appears in Windows 7 with the spinning circle for around 30 seconds. This is a tiny file, why is it taking so long. Its virtually instant if done on a Windows XP bootcamp machine or even in Windows 7 on an older Leopard iMac.
There really isnt a great deal regarding this problem oin the internet but it has occurred on all the new i5 Lion iMacs we have.
Does anyone have any other suggestions (serious ones ) that I could try?
I am currently installing the 32 bit version to see if it is a driver issue.
Cheers

isn't apple now using propritary drive firmware in 2011 imac?
I suspect 30 sec is drive delay spinup and is frequently happens with green drives, I have some and do this. swap for WD black or something.

Best Way To Display Photos On HDTV?

I would like to display photos on a HDTV (16:9 aspect ratio, 1280x720 pixel max) at the highest possible resolution.
The best photo quality, I assume, is obtained by connecting a computer’s DVI output (or a networked media server) directly to the HDTV’s DVI/HDMI/component video input, but my iBook doesn't have DVI out nor do I have a media server.
So the next option seems to be to burn the photos to a disc and play them through a DVD player, but from what I've read iDVD only supports resolutions of 720x540 (4:3) or 854x480 (16:9). And in fact the photos I've burned to disc using iDVD look fuzzy and are not HD quality. Is there any better way to burn them to disc and display something closer to the HDTV’s maximum resolution of 1280x720?
Does some form of photo CD or Roxio Toast’s Motion Pictures allow the display of higher resolution photos?

Hi Ted
i have checked Roxio's support and it states that you require an image from a 3 megapixel or higher camera to get the desired resolution for HD. toast 7, if you have it supports HD resolution of 720p(progressive) and 1080i(interlaced). so its recommended that when you create your masterpiece choose 720p which supports a resolution of 1280x720 and this setting is only available if you choose 16:9 instead of 4:3.
