How can I improve performance on my iPad 1. I am having problems with apps closing unexpectedly and also with slow response.

My iPad 1 has become almost unusable apps crash without warning and the response time is very slow.

1. Close all inactive apps in the Task Bar. Double-click the Home button and hold apps down for a second or two. Tap the minus sign to close app.
2. Hold the Sleep and Home button down for about 10 seconds until you see the Apple Logo.

How can I improve performance when scopes are open?
When Color correcting, performance severely lags, stalls, freezes!
Nothing to complex...simple 3 way color corrector, occasional curves filters.
I am constantly waiting for the timeline to update as I move around....sometimes as long as a minute or so.
I'm on brand new 2.7 Ghz 12-Core MacPro with 64 GB of RAM
Thanks in advance.

How can we improve performance while selection production orders from resb

Dear all,
there is a performance issue in a report which compares sales order and production order.
Below is the code, in this while reading production order data from resb with the below select statement.
can any body tell me how can we improve the performance? should we use indexing, if yes how to use indexing.
*read sales order data
SELECT vbeln posnr arktx zz_cl zz_qty
INTO (itab-vbeln, itab-sposnr, itab-arktx, itab-zz_cl, itab-zz_qty)
FROM vbap
WHERE vbeln = p_vbeln
AND   uepos = p_posnr.
    itab-so_qty = itab-zz_cl * itab-zz_qty / 1000.
    CONCATENATE itab-vbeln itab-sposnr
       INTO itab-document SEPARATED BY '/'.
    CLEAR total_pro.
**read production order data*
    SELECT aufnr posnr roms1 roanz
    INTO (itab-aufnr, itab-pposnr, itab-roms1, itab-roanz)
    FROM resb
    WHERE kdauf = p_vbeln
    AND   ablad = itab-sposnr+2.

Himanshu,
Put a break point before these two select statements and execute in the production.This way you will come to know which select statement is taking much time to get executed.
In both the select statements the where clause is not having the primary keys.
Coming to the point of selecting the data from vbap do check the SAP note no:-185530 accordigly modify the select statement.
As far as the table RESB is concerened here also the where clause doesn't have the primary keys.Do check the SAP Note No:-187906.
I guess not using primary keys is maring the performance.

How can I improve performance for BC4J/JSP-application

Hi,
I have developed a JSP-Applikcation with the master-detail views. This Application has been implemented
as SSO enabled web portlet into portal. Whenn I click on a row retrieved from the master view (Master.jsp), it take 15 seconds
until the associated data in detail view will be displayed on the other window(Detail.jsp). The master table has about 2500 records and detail table about 7000. (Other case: it takes 2 seconds for 162 rows (master) and 228 rows (detail) respectively)
In Master.jsp I set rangesize = "10" to reduce data loading time.
======================== master.jsp =================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" rangesize="10">
<a href="detail.jsp?RowKeyValue=<jbo:ShowValue datasource="dsMaster" dataitem="RowKey"/>">
Here Click
</a>
==================================================================
Because all records from master view have firstly to be retrieved to locate right row, I set rangesize="-1" in detail.jsp. Consequently this leads to a lower performance.
When rangesize="20" sets instead rangesize="-1", The performance is good, but the wanted Data from detail view are not displayed if the records of master view cliked on ist not in this range.
======================== detail.jsp ======================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" rangesize="-1">
<jbo:RefreshDataSource datasource="dsMaster">
<jbo:Row id="msRow" datasource="dsMaster" action="Find" rowkeyparam="RowkeyValue">
<jbo:dataSource id="dsDetail" appid="testAppId viewobject="DetailView">
======================================================================
Is my programming logic not to be suited for the high performance?
How can I improve the performance, if it is so?
Many thanks for your help.

Utl_raw.bit_and - how can I improve performance of this query?

Hi all
Hugely grateful for any light anyone can shed.
I need to do bit AND operations on 128 bit numbers and I'm stuck in Oracle 10g.
10g provides a very nice bitand() function that can be applied to numbers but it only works up to 64 bit numbers (actually only 62 I think because it needs a couple of bits)
So I've been looking at using the utl_raw.bit_and function. It works very well, except that I'm encountering a massive performance hit, which hopefully is in the way I'm using it, rather than intrinsic to the speed at which utl_raw.bit_and itself performs..
With numbers, I do a query like this:
select count(1) from offer_a where bitand(bit_column, 51432) = 51432
With utl_raw.bit_and (and 16-byte RAW column), I am passing in a hex value (may not be the best thing? Would passing in binary be better?) and doing my query like this:
select count(1) from offer_a where utl_raw.bit_and(bit_column,hextoraw('00000000000000000020008000002ca1')) = hextoraw('00000000000000000020008000002ca1');
One million rows using bitand takes about a second, using utl_raw.bit_and like this takes 25 seconds or so!!! Hopefully it's something in the way I'm calling it, and there's a faster way?
Thank you!
Jake

Hmm.. Actually it may not be that simple.
I had created an index on the number column that oracle seems to consistently use if I do a query like:
select count(1) from scott.offer_b where
current_price >= 0 and
bitand(current_price, 9008574719100165) = 9008574719100165
(without the >= oracle seems to do a full table scan. The reason I created the index is that there's other columns in the data table, making larger blocks. I figured that an index, even though most of needs to be scanned, would be faster because I can cram many more rows into each block..?).
But if I drop the index on the number column, it takes about 12 secs/1m rows, in other words about half the time of the utl_raw.bit_and().
So it's possible that bitand on 64 bits takes about half the time of utl_raw.bit_and on 128 bits, which is very reasonable..
So maybe the real problem I have is why oracle is not using the equivalent index that I placed on the RAW column when I do:
select count(1) from scott.offer_b where
hex_bit_sig >= '00000000000000000020008000002ca1' and
utl_raw.bit_and(hex_bit_sig,'00000000000000000020008000002ca1') = '00000000000000000020008000002ca1';
(By the way I realized that I don't need to use the hextoraw - seems like just putting a hex number in '' is the right way to specify a raw anyway?)
So yes, I think that's the real problem - how can I get oracle to use the index I created on the RAW value

The current version of the Mail app on Mac OS X doesn't include a "bounce" feature either as it is largely useless. Most spam comes from either bogus address or ones that aren't monitored.

How can I improve performance over a Branch Office IPsec vpn tunnel between and SA540 and an SA520

Hello,
I just deployed one Cisco SA540 and three SA520s.
The SA540 is at the Main Site.
The three SA520s are the the spoke sites.
Main Site:
Downstream Speed: 32 Mbps
Upstream Speed: 9.4 Mbps
Spoke Site#1:
Downstream Speed: 3.6 Mbps
Upstream Speed: 7.2 Mbps (yes, the US is faster than the DS at the time the speed test was taken).
The SA tunnels are "Established"
I see packets being tranmsitted and received.
Pinging across the tunnel has an average speed of 32 ms (which is good).
DNS resolves names to ip addresses flawlessly and quickly across the Inter-network.
But it takes from 10 to 15 minutes to log on to the domain from the Spoke Site#1 to the Main Site across the vpn tunnel.
It takes about 15 minutes to print across the vpn tunnel.
The remedy this, we have implemented Terminal Services across the Internet.
Printing takes about 1 minute over the Terminal Service Connection, while it takes about 15 minutes over the VPN.
Logging on to the network takes about 10 minutes over the vpn tunnel.
Using an LOB application takes about 2 minutes per transaction across the vpn tunnel; it takes seconds using Terminal Services.
I have used ASAs before in other implementation without any issues at all.
I am wondering if I replaced the SAs with ASAs, that they may fix my problem.
I wanted to go Small Business Pro, to take advantage of the promotions and because I am a Select Certified Partner, but from my experience, these SA vpn tunnels are unuseable.
I opened a case with Small Business Support on Friday evening, but they couldnt even figure out how to rename an IKE Policy Name (I figured out that you had to delete the IKE Policy; you cannot rename them once they are created).
Maybe the night weekend shift has a skeleton crew, and the best engineers are available at that time or something....i dont know.
I just know that my experience with the Cisco TAC has been great for the last 10 years.
My short experience with the Cisco Small Business Support Center has not been as great at all.
Bottom Line:
I am going to open another case with the Day Shift tomorrow and see if they can find a way to speed things up.
Now this is not just happening between the Main Site and Spoke Site #1 above. It is also happeninng between the Main Site and Spoke #2 (I think Spoke#2 has a Download Speed of about 3Mbps and and Upload Speed of about 0.5 Mbps.
Please help.
I would hate to dismiss SA5xx series without making sure it is not just a simple configuration setting.

Hi Anthony,
I agree!. My partner wants to just replace the SA5xxs with ASAs, as we have never had problems with ASA vpn performance.
But I want to know WHY this is happening too.
I will definitely run a sniffer trace to see what is happening.
Here are some other things I have learned from the Cisco Small Business Support Center (except for Item 1 which I learned from you!)
1. Upgrade the SA540 at the Main Site to 2.1.45.
2a. For cable connections, use the standard MTU of 1500 bytes.
2.b For DSL, use the following command to determine the largets MTU that will be sent without packet fragmentation:
ping -f -l packetsize
Perform the items below to see if this increases performance:
I was told by the Cisco Small Business Support Center that setting up a Manual Policy is not recommended; I am not sure why they stated this.
3a. Lower the IKE encryption algorithm from "AES-128" to DES.
3b. Lower the IKE authentication algorithm to MD5
3c. Also do the above for the VPN Policy
Any input is welcome!

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

How can i improve performance of a horizontal parallax on an mobile device?

I've created a Horizontal Parallax website using Adobe Muse, and it works perfectly on a desktop machine, but as you use it on a mobile device such as an iPad, the performance becomes jerky and jumpy.
I added navigation buttons to jump to set keypoints, which again, work smoothly on a desktop, but then jump on a mobile device.
Is there any way to prevent this jumpy motion and make it more smooth?
Thanks in advance!

Its just scrolling images. A Horizontal Parallax, (the pages are placed in the project vertically, as suggested by adobe). There are no animated images, no videos either. All are just transparent PNGs with scroll effect attached.
It seems jumpy if you use it on the ipad, both through scrolling, but even worse if you use the navigation i've implemented, which is supposed to scroll to the anchor point.

How can i improve the batterylife?(iPad 2)

Could you help me?

The iPad 2 camera is not the equivalent of the iPhone 3GS which has a 3-megapixel camera (resolution: 2048x1536 pixels). The iPod 2 rear-facing camera is really for HD video (1280x720 which is less than a megapixel).
To get the best pictures shoot in good light and don't use the digital zoom. The iPad 2 camera is not intended for high quality still photography.

How can I improve performance (image searching)

Hello,
My program makes many calls to a method that compares two images. It does this by using nested for-loops (one for x-pixel and one for y-pixel) to search through a BufferedImage image and use getRGB() to compare pixel-by-pixel to see if the two images are the same.
I've added a little bit of "optimisation" that first compares the central 5-pixles (the 5 pixels in an "X" shape in the middle of each image), and will only continue to search pixel-by-pixel if those are shown to be the same.
Of course, both searches (the optimisation-pre-search and the pixel-by-pixel search) will quit out of the loops and return false as soon as one non-matching pixel is found.
The problem is that it has to do this millions of times. For every single pixel in the source image, it has to go through one-by-one and compare, starting with the "optimised" speedy-compare and then moving on.

Try this:
public static boolean areImagesIdentical(File file1, File file2) throws IOException {
          // Safe to do this?
          if(file1.getAbsolutePath().equals(file2.getAbsolutePath())) {
               System.out.println("files are same - same path");
               return true;
          if(file1.length() != file2.length()) {
               System.out.println("files are different, different file size");
               return false;
          BufferedImage image1 = ImageIO.read(file1);
          BufferedImage image2 = ImageIO.read(file2);
          if(image1.getHeight() != image2.getHeight() || image1.getWidth() != image2.getWidth()) {
               System.out.println("files are different, different height or width");
               return false;
          // Take 10 pixels from anywhere in each image
          for(int i=0; i<10; i++) {
               int x = (int) (Math.random() * image1.getWidth());
               int y = (int) (Math.random() * image1.getHeight());
               if(image1.getRGB(x, y) != image2.getRGB(x, y)) {
                    return false;
          int[] image1AllRGBs = image1.getRGB(0, 0, image1.getWidth(), image1.getHeight(), null, 0, image1.getWidth());
          int[] image2AllRGBs = image2.getRGB(0, 0, image2.getWidth(), image2.getHeight(), null, 0, image2.getWidth());
          return Arrays.equals(image1AllRGBs, image2AllRGBs);
     }

How can i copy multiple projects that reference one event without having to duplicate the event over and over for each project?

Each project has compound and regular media in them, and every time i attempt to duplicate the projects and have them reference one event on the new drive the rest of my media shows up missing and will not reconect. Wondering if anyone has had to tackle this problem. I have a limited amount of space on my Drobo thunderbolt drives and need to optomize it. Thank you

So i called apple and after a few hours on the phone and them taking control of my computer they pretty much told me they had never seen this before and were sorry they couldnt assist in any way. The long explination is that i work for a company that films their footage in one long take and then sends it to me to cut into segments, i then have to copy these small edits which are all in different projects and the one large event over to a new hard drive to give to a guy to put titles on and then send back to the company. when i do this copy of project final cut X forces me to also duplicate the event leaving me with "event" (fcp1) and so on depending on how many projects there are. When i dont duplicate event and project together the whole project shows up as missing media and final cut X does not recognize that the original footage is being lost and therefor i am not even given the oportunity to reconect media. I have tried all conventional ways of copying and transfering and have an extensive background in editing and have never come across this, but then again this is final cut X and something that i try and stray away from if i have a choice in systems.
to answer Tony im using copy project and event because it is the only option that works (copy project and used media works as well but only creates more confusion with having to rename files) I would prefer to be able to just copy the first project and event and then be able to source the rest of the project files from the first event i copied over.
