• Performance issues with large number of nodes

  I am creating an application to display graphics (large), for example:

  

  But I ran into some performance issues, even for a relatively small number of nodes in the scene graph (+-2000 in the picture above). The graph is built, step by step, adding circles and paths to a StackPane. Circles and paths can be semi-transparant. For a small number of nodes, I get a solid 60 FPS, but this decreases over time to about 5 frames per second. As soon as I stop adding new nodes, the framerate shoot again up to 60 images per second. The framerate drop even when all the nodes are outside the viewport.

  My questions are:

  * Is Platform.runLater () call to 2000 times a minute too?

  * This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)
  * JavaFX pulse recorder says such things, are there meaningful information in that I'm missing?

  PULSE: 1287 [163MS:321MS]

  T14 (0 + 0ms): col of CSS

  T14 (0 + 5ms): layout pass

  T14 (6 + 152ms): waiting for the minutes of the previous

  T14 (158 + 0ms): copy the State for graphic rendering

  T12 (159 + 0ms): dirty opts calculated

  T12: Path of the slow form for null

  T12 (159 + 160ms): painted

  T12 (319 + 2ms): Presentable.present

  T12 (321 + 0ms): completed the presentation of painter

  Counters:

  Background image of the region used cached: 14

  NGRegion renderBackgroundShape slow path: 1

  Nodes displayed: 1839

  Nodes visited during rendering: 1840

  Basically, try some optimization of performance ranging from the simple to the complex.   Each of the changes below may provide you with an increase in performance.  Some will probably increase performance much more that others (depending on where is the real bottleneck).  I would probably start by replace the paths to the lines and reduce the number of Platform.runLater calls (as adding nodes that fall within the viewport can be difficult only).

  > The framerate drop even when all the nodes are outside the viewport.

  Place the nodes in the graph, which fall inside the viewport.

  > Is Platform.runLater () call to 2000 times a minute too?

  Yes, there is no reason to call it more than 60 times a minute when the framerate of JavaFX is capped at 60 frames per second by default.

  > This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)

  Yes, it's a graphics system relatively low-end.  But, look at the comment of developer below - your CPU and choice of graphic primitives can also affect rendering speed.

  > Adding circles and the paths to a StackPane

  You don't need a StackPane to this, a group is a container easier and probably better.

  > may be semi-transparant

  Remove transparency * may * cause acceleration.

  You run may be:

  https://JavaFX-JIRA.Kenai.com/browse/RT-20405 : improve the rendering of path performance

  Maybe if you use lines rather than the paths, performance might improve.

  A comment by a developer on this performance tweak application is:

  «It is quite normal for applications that use arbitrary paths (if the node path objects, SVGPath, polyline, or polygon) because these paths are rendered in software.» As card circle, Ellipse, line and Rectangle very primitive forms easily to the operations that can be performed entirely on the GPU, which makes them essentially cheap. There is no need to compare the rendering of a complicated shape for rendering of simple primitives for this reason. »

  ----

  Setting the cache indicators can help, but probably only if you animate nodes.

  ----

  Present level of detail of your graph functionality so a chart with zoom out is not make as many nodes as a part of zoomed in.

  ----

  You run any code important calculation on the JavaFX application thread that could stall it?

  Can make you available a ftom so that others can reproduce your problems?

  The server has 16 GB of Ram... way means that, due to limitations of 32-bit on windows only 4 GB of Ram was used and the 12 remaining GB is inactive?
  What is the proper way to tune?

  There are restrictions on how the memory beyond 4 GB can be used by Oracle. As far as I know, the memory is reserved for the buffer cache.

  Not all memory below the 4 GB limit is available for programs. Some of this memory is laid out in memory of the device, such as the video cards, RAID cache on board, etc., and some of the memory Windows is needed to track the objects window, icons, etc. Although it is possible to back up 2 GB per process limit to 3 GB, making Windows limit to use for its own purposes the memory that remains after the memory is drawn to embedded devices, and I think that the Oracle Metalink site does not recommend trying to go up the by the limit process completely to 3 GB. And this low by the process boundary should be reserved for the memory window. Your current value of pga_aggregate_target should be checked, because there is no way that the apparent present value could enter into the available memory.

  I agree with Martin - the best way to take full advantage of the memory is to pass on a 64-bit platform. Most, if not all the memory limit headaches disappear on a 64-bit platform. Of Windows 2003 Standard edition supports up to 32 GB of memory, this could be an option for you. It may or may not be a huge effort, but this means system loss of time (which can be considered a reason to call it a huge effort). You will probably find that the server, if less then three years, will support a 64 bit version of the operating system, but check the 64-bit versions of all the drivers are available and consider replacing hard disks containing the operating system if you need to return to the current operating system.

• Performance issues when you build a large crossroads

  Hello
  
  I have a performance issues when you build a large crossroads.
  
  So here's my situation:
  
  We use Discoverer Plus 10.1.2.45.46c
  Database Oracle 9.2.0.6 on Windows 2003
  OAS 10.1.0.3
  1.5 GB of RAM on my PC
  
  -J' planned a workbook with 1 single worksheet that takes 2 minutes to run. The table generated in the database to store the results from 19 columns and rows to about 225000 (I know that's a lot, but it is what the customer needs).
  
  -When I opened the workbook, it takes about 2 hours to recover the data. The data is retrieved in groups of 1000 and at the beginning, the lines are read much faster than at the end. There are also 15 minutes more to build the crosstab. So overall, it takes 2 hours and 15 minutes for the crosstab display on my screen.
  
  Can someone explain to me:
  -Why does take so long?
  -What can I do to improve the execution other than changing the application or displaying the results in a regular tab? Is there some setting that I can do on the database of the Oracle Application Server?
  
  Note: I have reproduced the worksheet in a simple tab and demand it. The table generated in the DB to store the results is the same and it takes only 2-3 minutes to open this spreadsheet and extract all lines.
  
  
  Thank you!
  
  Mary

  Hi Mary
  If you have 225 000 lines in your basic spreadsheet, then it will take a lot of time to produce a crosstab. The reason is that Finder can not calculate how many buckets he needs until he has read all the data. I can almost guarantee that with 225 000 lines to read and manipulate that you are short of memory.

  You might be better suited someone create and populate a table with the results you need rather than try to get the discoverer to calculate values in crosstab on the fly. If the final result of the crosstab is a few lines of aggregated data, then this is what is right for your table. The advantage of using a table and a few SQL (or PL/SQL) is that you will not be using your local computer during the aggregation / sorting phase. Don't forget a crosstab also sort based on the values in the left columns, the columns you have aggregations (buckets) you will have and most necessary sort. Using a table, you can index or even partition the results that will make for a much faster recovery.

  As a tip, recommend Oracle, confirmed by myself during the exhaustive tests, no do not build large paintings to double entry due to the performance of touch that you will have. The tables are much more efficient because you can pull back x lines at once. You can't do that with a crosstab and all values must be read before that whatever it is is displayed.

  Does that help?

• Performance problems with large Photo library size

  Did anyone seen performance issues when the library becomes too great? I used to keep a few different libraries, since some of my libraries are already 1 TB. So, if I merge into one, the file will be 2-3 Tb when it's said and done. Anyone know if it is recommended to size limits or is it more important with El Capitan. Obviously, the response time will be affected by the hard drive and the speed of the laptop, but before you begin merging into one file libraries, I wanted to see if anyone had any suggestions/recommendations or other related advice. Thank you!

  It is not documented, but how many pictures a library can contain pictures, you can migrate photos iPhoto libraries and libraries Aperture, so you should be able to store at least 1 000 000 photos in a photo library.

  I haven't noticed any performance issue with a large library of Photos.  My largest library has 40000 photos.

  During the regular work with the size of the library is not serious at all, as long as you want to keep enough free storage on your system drive. Don't let the photo library fill in your system drive. Keep at least 10 GB free at all times, better more.

  However, there are rare occasions when the size will be discussed:

  • When you need repair library, it will take more time, if the library is large.
  • When you first migrate your libraries of photos, the initial treatment will take longer - scanning for faces and places, creating thumbnails.
  • If you use iCloud library synchronization can take a long time for a large library.
  • Too many smart albums can make pictures a little slower, if the library is large.  I noticed a drop in performance, after that I created 200 smart albums with a search for text across the entire library.

• Smartphone blackBerry Storm performance issues (and suggestions)

  I want to start and say that I don't like my phone.  When it works (which is most of the time), it works fine.

  But there are certainly problems of software.  As a software engineer, the OS has some memory serious management problems.  This seems to cause most of the problems I'm having with the phone.  I'm running the latest Verizon S/W (v4.7.0.148).

  Problem #1:

  I am a paranoid person.  There are a lot of personal information on my phone, I have currently international calls helped that I need this feature.  So to protect me my phone is locked when it is the case or after a period of inactivity time.  It is a good practice.  Part of the draw to the fate of the Blackberry is the security that you can configure on the device (I'm not paranoid enough to allow all the protections of encryption - yet).  Problem of the storm is that it can take 1 to 5 minutes to get the phone unlocked when unholstering.  It is not an exaggeration.  As the performance of the memory gets worse, time takes more time.  If I had to make an emergency call, it could be the difference between life and death.  5 minutes is a long time to wait to call 911.  This must be corrected!

  Problem #2:

  The phone must be "reset" once a day to remember "lost."  It is just poor programming.  I don't know if this problem of BB OS or Apps I'm running, but in both cases, this isn't fair.  After the reboot if I go to the display of memory under options I could have about 3-5 MB of free memory.  After a few hours of use, this will almost always '0 '.  I installed MemoryUp Pro, which seems to have extended the period of time between the battery grips, but I still don't think we should ask all owners of BB Storm to pull there battery once a day.  The other answer I get is "do not run so many Apps.  I get all my applications when finished.  Are the only ones that I continue to turn: Blackberry Messenger, Yahoo Messenger, Google Talk and Google Maps (Latitude).  Other applications running, you can't get out (phone, browser).  I tried doesn't work is not the 'optional' tricks and performance has not really much better.

  Problem #3:

  Missed calls.  This is probably related to problems of memory above, but if the storm can be used as a phone, then I should buy something else.  Although the occurrence of this problem has gone down because I installed MemoryUp Pro and perform the reset once a day, sometimes still about 1 to 5 times.  It takes so long for the phone to 'wake up' when a call comes in (especially if it is holstered), at the time where I hit "Answer", a call has been Messaging voice or even worse, the phone doesn't ring at all.  All I get is a notification of appeal lacks the 'unknown number '.

  Problem #4:

  Battery performance could be improved.  The battery that comes with the storm has about 24 hours on 24 with the Radio and Bluetooth.  Really, this isn't a problem if you know it.  I solved the problem by buying a 2700 mAh battery for extended life of BoxWave I use when traveling.  Makes the storm bit bulky, it will give me 2-3 days of life.  I don't know how this could be improved if not

  I hope that the developers of RIM are trying to solve some of these performance issues.  Certain tasks should be a higher priority as they seem to have (like phone & Unlock).

• Adobe Air performance issues?

  I have recently finished a huge project in Adobe Muse and I love the new sensitive design tools. However, as the project continued to develop, Muse has become increasingly slow to react and interact with the sensitive cursor was almost impossible. As someone who worked for Apple, I'd be the first person to point the finger my Mac and offer to buy a new computer, but it is a new, maxed-out MacBook Pro 15 inches. All other Adobe CC applications work without problem. When Muse was first published, as I remember, it was written on top of the Adobe AIR platform, instead of being natively written in C++. That this has something to do with performance issues that I see? If so, is there something I can do to improve performance, I see?

  Air is not basis for Muse more for a long time. Nativly revised muse was released in early 2014.

  In my view, the Muse team works actively on performance boosts, but I think that we should not expect any miracle: no other application I know not a calculate and display real-time changing dynamically and the same objects interactively from time on endless pages in response.

  In my opinion, the only way to significantly increase the speed would be gray on all goods during the move of the scrubber.

• Performance issues when you use HTML5-Articles

  Hello world

  We build an application where we use HTML5-sensitive inside objects.

  On older iOS Devices (iPad2 iPad4 for example) and the performance is so bad that it is not really usable. Take for example up to 15 seconds of opening an Article downloaded until it is fully restored.

  We have a lot of photos and videos inside but inside the browser OS, it works a lot better.

  Is there anyone who has had the same issues or any idea how to optimize performance (especially on older devices)?

  Thanks in advance and best regards!

  Lars

  Lars salvation,

  The control of the OS used to display content on iOS is a different rendering than the OS browser technology and has different performance characteristics. In particular, it is slower on older devices, such as the iPad 2.

  Based on your description my guess is that your image size is driving performance issues. Take a look at what size in pixels are your images and aggressively, re - compress. I had successful scaling of images to 50% of the size I think I need and then save them in JPEG format at a quality level of 7 (or even 5) in Photoshop.

  Regarding the videos, make sure that you use the

  2 order services and uninstalled the application

  3. has taken a backup of the MS - SQL Database and and got up a new database in its place

  4. install the new version of the application 5.5

  5 import the configuration and the packages in the application.

  Has anyone seen this behavior? or better yet have a fix for this?  5.5 seems to be significantly slower than version 5.1, we were in front.

• CC Dreamweaver performance issues

  There are some performance issues, I wanted to implement.

  1. very slow to open new files

  Particularly noticeable on Mac OS 10.9 Mavericks. I work with PHP, javascript, html, css. And they all seem to be affected. It takes more than 10 seconds with the wheel that appears just to open a single file.

  2 slow down scrolling display of "files".

  I have a large site with over 900 documents within multiple levels of subfolders (not including images, etc.). I realize I'm not all clients, but it seems that there could be some performance tuning done here. I have a modern Macbook Pro that should have no trouble scrolling through or even thousands of files.

  Hello Jeremy,.

  Glad to hear that you do not see the shift as previously, while opening the files now.

  For the 2nd edition, we have a bug connected to improve performance while scrolling of files for a large site. Bug is currently under review and analysis.

• Performance issues with Photoshop CS6 64-Bit

  Hello-

  Issue at hand: in recent weeks, I noticed significant problems with performance since the last update PS CS6 using the Adobe Application Manager, from the unexpected shut downs to bring my computer to a crawl (literally, my cursor seems to crawl on my screens). I'm curious to know if anyone knows these issues, or if there is a solution I have not yet tried. Here is a list of actions that give rise to these performance issues - there are probably more that I have not experienced due to my frustration, or were not documented as occurring several times:

  • Opening files - results by hanging processes, takes 3-10 seconds to solve
  • Paste from the Clipboard - results by hanging processes, takes 3-10 seconds to solve
  • Saving files - takes 3-10 seconds to open the dialog box, another 3 to 10 seconds to return to the normal window (saving an image PNG compressed)
  • The eyedropper tool - will crash Photoshop on the desktop, or take 5 to 15 seconds to load
  • Try to navigate any menu - Photoshop crash on the office or take 5 to 15 seconds to load

  Attempts I took to solve this issue, which failed:

  • Uninstalled all fonts I have added since the last update (it's a pain in the *, thanks to be glitch Windows Explorer)
    
  • Uninstall and reinstall the application
  • Edition 32-bit use
  • Change process priority to above normal
  • Confirm the process for all available cores of the processor affinity
  • Change the configuration of the performance of Photoshop options
    • 61% of memory is available to Photoshop to use (8969 MB)
    • History States: 20; Cache levels: 6; Tile cache size: 1024K
    • Records of work: active on the production of SSD, ~ 10GB of available space
    • Dedicated graphics processor is selected (2 x nVidia cards in SLI)

  System information:

  • Intel i7 2600 K @ 3.40 GHz
    
  • 16 GB of RAM Dual Channel DDR3 memory
  • 2 x nVidia GeForce GTS 450 cards, 1 GB each
  • Windows 7 Professional 64 bit
  • Adobe Creative Cloud

  This problem is cost me time that I work every day, and I'm about to start looking for alternatives and cancel my subscription if I can't get this resolved.

• DPS - simple edition - PDF rendering, text of multi-State performance issues

  Hello

  

  Please advise on the question above...

  On a retina display ipad, I have problems with States multiple objects that contain text. The left column is a clear text, object not multi-state. However when I place the text in a multi (right) state object it is not rendered in high resolution. A bit pixelated.

  One question - Cloud Creative License

  My application is compiled using the version of the app: v24

  I also experienced performance issues of the use of the PDF manual... When you edit a page, everything is super grainy and then ~ 2 seconds later it makes crisp. It used to be made in advance, or much faster. Maybe I was using PNG? I went in mode like PDF than recommended in countless articles. Is that the slow makes just an induced effect of PDF? What can I do to optimize? Recommendations?

  Thank you very much!

  You must select PDF as the format and optionally vector in the slide show of the Group Folio overlays pane.

  And Yes, the delay in rendering is something you have to live with for now.

• Performance issues at the opening of business rule

  Hello
  
  We work in collaboration with Hyperion version 9.2.1 and we have performance issues when opening the business rules. I have analyzed the issue and discovered that it has something to do with the assignment of access privileges to the rule.
  
  The authorisation scheme looks like as follows:
  
  User A is assigned to the group G1
  User B is assigned to the Group G2
  Group G1 is assigned to the XYZ group
  Group is assigned to the XYZ group G2
  Group XYZ is the owner of the 'basic user' delivery to the planning application.
  
  Without attributing any unrestricted access the rule company opens immediately.
  By assigning the privilege to access the group G1/G2 (post or get) the business rule opens immediately.
  By assigning access privilege to the XYZ group the business rule opens after 2-5 minutes.
  
  Anyone has an idea why this happens and how to fix this?
  
  Kind regards
  ULI
  
  Edited by: user13110201 the 12.05.2010 04:31

  This was a problem with the business rules for quite some time. Oracle made front and rear markets in later versions than yours; and they have issued patches address, if it is not completely solved the problem. Finally things seem to be much better in 11.1.1.3, although YMMV.

• Performance issue of SAP with Oracle 10 on Sun SPARC T5240 server

  Dear friends,
  
  We have a performance issue after the migration of our basic system of SAP ERP 6.0. To new servers, we moved a month ago.
  The report of EarlyWatchAlert SAP response time of CPU is too high, although the CPU utilization is never more than 5%,
  
  The current system is:
  
  Database server: Sun SPARC Enterprise T5240 Server - 2 CPU´s with 6 core wire 8, 1.2 Ghz 32 GB RAM
  and we use a different identical server configured as an application server.
  
  Database is Oracle 10.2.0 and Solaris 10 operating system.
  
  The problem is CPU average response time is 450 ms and maximum CPU load is 5% percent.
  
  Configuration prior to migration with the old servers, we got the answer of CPU: 150 ms and max CPU load: 50%.
  Old configuration: 2 X HP rp3440, 2 X PA 8800 (2 core, 1.0 GHz) CPU.
  
  You have experience with a similar situation, setting that could be bad for server CPU´s not making full use?
  or you know any similar configuration for benchmark?
