Jdeveloper performance issue

Jdeveloper 11.1.1.6
I observe that Jdev is very slow & hangs often, though I am having 8 GB RAM in my PC. Found certain articles in the web to improve Jdev performance & made the following changes in the Jdev configuration files:
$JDEV_HOME/jdeveloper/jdev/bin/jdev.conf
#AddVMOption -XX:MaxPermSize=256M
AddVMOption -XX:MaxPermSize=1024M
AddVMOption -DMainWindow.MemoryMonitorOn=true
$JDEV_HOME/jdeveloper/ide/bin/ide.conf
#AddVMOption -Xmx640M
#AddVMOption -Xms128M
AddVMOption -Xmx640M
AddVMOption -Xms640M
After making the above changes (rows prefixed with # are the original values; getting virtual memory issue if these values are increased more than these), I observed only marginal improvement.
Any thing else to be done to improve Jdev 11.1.1.6 performance?

Hi Timo,
I work on a PC with Windows 7 64 bit OS. Java version details given below:
java version "1.7.0_15"
Java(TM) SE Runtime Environment (build 1.7.0_15-b03)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
I do have an anti-virus software, but I don't see a problem there as my other applications work smoothly.
My jdev hangs mostly when I drag & drop a data control into my form. Other operations like drag & drop within the structure, switching to XML source, typing in XML source etc. are slow.
While running Jdev, I have my outlook, pl/sql developer & the browser windows. I checked in task manager. Hardly 70-75% memory is occupied.

  • Jdeveloper performance issues on Core 2 Quad PC

    Hello,
    I'm fairly new to the forums, I've read a lot but never posted anything, well, on to the problem.
    At work my company uses Jdeveloper, I'm on a low Pentium Dual Core @ 2.66Ghz, and 2GB of ram, not the best computer but it does the job.
    I recently installed the latest version of Jdeveloper at my personal computer (at home) which is a Core 2 Quad @ 2.4Ghz, 4GB ram, Nvidia 8800GT 512MB.... It's a good computer and Jdeveloper is a lot slower on my personal computer than on my work's computer.
    I've noticed that Jdeveloper uses both cores at work, but only 1 out of 4 at my home's computer, anyone know what seems to be the problem here? why isn't it seeing the rest of the cores? I checked the jdev.conf settings and the 1 core thing isn't on, it should see all 4, any ideas?
    Help would be greatly appreciated. Thanks in advance for your replies.

    Hello Frank,
    I've had this computer since December, and every program either uses 2 Cores or all 4, I've read about certain programs not able to identify a Quad core as such and only use 1 core.
    None of my programs does this... except for Jdeveloper and it's irritating that even programs I don't need or like can use several cores and Jdev (the one I actually need to go fast) doesn't seem to be able to recognize the processor or something...
    Anyone have any experience on this?
    Thanks in advance for your replies.

  • Performance issue with Jdeveloper

    Hi Guys,
    I am experiencing strange performance issue with Jdeveloper 10.1.3.3.0.4157. There are many other threads regarding the performance issue in this forum, but the problem I have is a little bit different.
    I have two computers: one is Athlon 3200+ with Vista and another one is P4 dual core 6400 with XP (service pack 2). Both of them have 2GB memory.
    I am running the same simple project on both computer, but only the one with Vista has the problem. The problem is very similar to the problem mentioned in the thread:
    Re: IDE has become extremely slow?
    But it's much worse. It only happens only on JSF pages. Basically, any operations on the JSF pages are very slow. Loading the page, changing the attributes of a button in source editor, or even clicking the items in the design view take forever to run.
    The first weird thing is that it may use 100% CPU, but it never recover, which means the 100% CPU usage never stops or when it stops, the Jdeveloper stops responding.
    The second weird thing is that the project is not big. Actually, it's very small. The problem started to happen since last week. There are not big changes during the period. The only thing I can say is that we created two more JSF pages.
    The third weird thing is that the same project never happened on the P4+XP box. When I open the project on the P4+XP box, it’s always fast and no CPU spike.
    Any advises are welcome!
    Thanks,
    Steven

    Hi Guys,
    I re-made a simple test project for this problem and now I now always reproduce the problem in JDeveloper on both system (XP & Vista). Everytime I open this jspx file in the source editor and try to scroll up/down the source file, or manually delete an attribute, JDeveloepr will hang and the CPU usage is 0%.
    Here is the content of the test file:

  • Performance issues with LOV bindings in 3-tier BC4J architecture

    We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
    One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
    To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
    We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
    The performance is OK (if not great) when the same code is running as 2-tier.
    Does anyone have any good suggestions?

    I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
    They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
    A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
    A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
    We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
    as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
    of time to tune up our codes but that helped very little. Eventually, we found
    the problem seemed to happen on TCP level. There is a 200ms delay in TCP
    level. After we read some documents about Nagle Algorithm,  we disabled a
    registry key (TcpDelAckTicks) in windows2000  on both client and server. This
    makes our program a lot faster.
    Anyway, we think we should provide our clients a better solution other than
    changing windows registry for them, for example, there may be a way to disable
    that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
    or anywhere in our codes. We have not figured out yet.
    Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
    Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
    The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
    See Also http://support.microsoft.com/default.aspx?kbid=328890
    "New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
    Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue.

  • Performance Issue : Why does ADF Taskflow Portlet (JSF bridge portlet) loading ADF Specific images, css, js everytime from portlet producer with dynamic URL with portlet_id and context parameters?

    Hi All,
    We have used WSRP Portlet in Webcenter Portal Page. The Portlet is created using JSF Bridge out of ADF Bounded Taskflow.
    It is causing Performance issue. Every time static content like js, css and images URLs are downloaded  and the URL contain portlet_id and few other dynamic parameters like resource_id, client_id etc.
    We are not able to cache these static content as these contains dynamic URL. This ADF Specific  images, js and css files  are taking longer time to load.
    Sample URL:
    /<PORTAL_CONTEXT>/resourceproxy/~.clientId~3D-1~26resourceId~3Dresource-url~25253Dhttp~2525253A~2525252F~2525252F<10.*.*.*>~2525253A7020~2525252FportletProdApp~2525252Fafr~2525252Fring_60.gif~26locale~3Den~26checksum~3D3e839bc581d5ce6858c88e7cb3f17d073c0091c7/ring_60.gif

    Please suggest , how this performance issue can be resolved?
    Thanks.
    Regards,
    Digesh

    Strange...
    I can't reproduce this because i have issues with creating portlets... If i can solve this issue i will do some testing and see if i can reproduce the issue...
    Can you create a new producer with a single portlet that uses a simple taskflow and see if that works?
    Are you also using business components in the taskflows or something? You can try removing some parts of the taskflow and test if it works so you can identify the component(s) that causes the issues.

  • Report Performance Issue - Activity

    Hi gurus,
    I'm developing an Activity report using Transactional database (Online real time object).
    the purpose of the report is to list down all contacts related activities and activities NOT related to Contact by activity owner (user id).
    In order to fullfill that requirment I've created 2 report
    1) All Activities related to Contact -- Report A
    pull in Acitivity ID , Activity Type, Status, Contact ID
    2) All Activities not related to Contact UNION All Activities related to Contact (Base report) -- Report B
    to get the list of activities not related to contact i'm using Advanced filter based on result of another request which is I think is the part that slow down the query.
    <Activity ID not equal to any Activity ID in Report B>
    Anyone encountered performance issue due to the advanced filter in analytic before?
    any input is really appriciated
    Thanks in advanced,
    Fina

    Fina,
    Union is always the last option. If you can get all record in one report, do not use union.
    since all records, which you are targeting, are in the activity subject area, it is not nessecery to combine reports. add a column with the following logic
    if contact id is null (or = 'Unspecified') then owner name else contact name
    Hopefully, this is helping.

  • Report performance Issue in BI Answers

    Hi All,
    We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
    Could any once suggest to improve the performance in BI answers?
    Thanks in advance,

    I hope you dont have many case statements and complex calculations that you do in the Answers.
    Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
    hope it helps
    thanks

    556GB LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed (RAID 0)
    I have other RAID installed, but not relevant for the present post...
    PSU
    Cosair 1000 Watts
    After many days of tests, I wanna share my results with community and comment them.
    CPU Introduction
    I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
    Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it.  I used Prime 95 to get the result.  // I know this seem to be ordinary, but you will understand soon...
    The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel.  The CPU gives everything it can !
    Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
    (picture 1)
    Disk Introduction
    I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
    Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
    The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
    Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
    (picture 2)
    Now, I know my limits !  It's time to enter deeper in the subject !
    PPBM5 (H.264) Result
    I rendered the sequence (H.264) using Adobe Media Encoder.
    The result :
    My CPU is not used at 100%, the turn around 50%
    My Disk is totally idle !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate seem to be a wave (up and down).  Probably caused by (Encrypt time....  write.... Encrypt time.... write...)  // It's ok, ~5Mb/sec during transfert rate !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  39 Go RAM free after the test !  // Excellent
    ~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
    GPU Load on card seem to be a wave also ! (up and down)  ~40% usage of GPU during the process of encoding.
    GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
    Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process.  Why ????  Is there some time delay in the encoding process ?
    Other : Quadro 6000 & GTX 680 gives the same result !
    (picture 3)
    PPBM5 (Disk Test) Result (RAID LSI)
    I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
    The result :
    My CPU is not used at 100%
    My Disk wave and wave again, but far far from the limit !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate wave and wave again (up and down).  Probably caused by (Buffering time....  write.... Buffering time.... write...)  // It's ok, ~375Mb/sec peak during transfert rate !  Easy !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  40.5 Go RAM free after the test !  // Excellent
    ~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
    GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
    GPU Ram get 400Mb of RAM (No usage for encoding)
    Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process.  Why ????  Is there some time delay in the encoding process ?
    (picture 4)
    PPBM5 (Disk Test) Result (Direct in RAMDrive)
    I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
    Comment/Question : Look at the transfert rate under (picture 5).  It's exactly the same speed than with my RAID 0 LSI controller.  Impossible !  Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage.  CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%).  // This kind of results let me REALLY confused.  It's smell bug and big problem with hardware and IO usage in CS6 !
    (picture 5)
    PPBM5 (MPEG-DVD) Result
    I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
    The result :
    My CPU is not used at 100%
    My Disk is totally idle !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate wave and wave again (up and down).  Probably caused by (Encoding time....  write.... Encoding time.... write...)  // It's ok, ~2Mb/sec during transfert rate !  Real Joke !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  40 Go RAM free after the test !  // Excellent
    ~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
    GPU Load on card = 100 (This use the maximum of my GPU)
    GPU Ram get 1Gb of RAM
    Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only.  Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
    Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).
    (picture 6)
    Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
    You can look the result in the picture.
    Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process.  Why ????   Adobe Premiere seem to have some bug with thread management.  My hardware is idle !  I understand AVCHD can be very difficult to decode, but where is the waste ?  My computer want, but the software not !
    (picture 7)
    Render composition using 3D Raytracer in After Effects CS6
    You can look the result in the picture.
    Comment : GPU seems to be the bottle neck when using After Effects.  CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
    Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.
    (picture 8)
    Conclusion
    There is nothing you can do (I thing) with CS6 to get better performance actually.  GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card).  Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance).  I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU.  I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
    Premiere Pro, I'm speechless !  Premiere Pro is not able to get max performance of my computer.  Not just 10% or 20%, but average 60%.  I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor.  But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post.  It's seem to be a bug...
    Thank you.

    Patrick,
    I can't explain everything, but let me give you some background as I understand it.
    The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
    The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
    As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
    The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
    You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
    There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.

  • Performance Issue for BI system

    Hello,
    We are facing performance issues for BI System. Its a preproductive system and its performance is degrading badly everyday. I was checking system came to know program buffer hit ratio is increaasing everyday due to high Swaps. So asked to change the parameter abap/buffersize which was 300Mb to 500Mb. But still no major improvement is found in the system.
    There is 16GB Ram available and Server is HP-UX and with Netweaver2004s with Oracle 10.2.0.4.0 installed in it.
    The Main problem is while running a report or creating a query is taking way too long time.
    Kindly help me.

    Hello SIva,
    Thanks for your reply but i have checked ST02 and ST03 and also SM50 and its normal
    we are having 9 dialog processes, 3 Background , 2 Update and 1 spool.
    No one is using the system currently but in ST02 i can see the swaps are in red.

    Hi James,
    Could you give me a call, I am at my desk.
    I had meetings all day and couldn't respond to your calls earlier.

    Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
    Hello,
    I just want to reiterate that we are very committed to working on
    this issue, and that our goal is to find out the root of the problem. But
    first I'd like to narrow down the avenues by process of elimination.
    Open Cursor is something that is commonly used in today's RDBMS. I
    know that you must test your query in ISQL using some kind of execute
    immediate, but Sybase should be able to handle an open cursor. I was
    wondering if your Sybase expert commented on the fact that the server is
    not responding to commonly used command like 'open cursor'. According to
    our developer, we are merely following the API from Sybase, and open cursor
    is not something that particularly slows down a query for several minutes
    (except maybe the very first time). The logs show that Forte is waiting for
    a status from the DB server. Actually, using prepared statements and open
    cursor ends up being more efficient in the long run.
    Some questions:
    1) Have you tried to do a prepared statement with open cursor in your ISQL
    session? If so, did it have the same slowness?
    2) How big is the table you are querying? How many rows are there? How many
    are returned?
    3) When there is a hang in Forte, is there disk-spinning or CPU usage in
    the database server side? On the Forte side? Absolutely no activity at all?
    We actually have a Sybase set-up here, and if you wish, we could test out
    your database and Forte PEX here. Since your queries seems to be running
    off of only one table, this might be the best option, as we could look at
    everything here, in house. To do this:
    a) BCP out the data into a flat file. (character format to make it portable)
    b) we need a script to create the table and indexes.
    c) the Forte PEX file of the app to test this out.
    d) the SQL staement that you issue in ISQL for comparison.
    If the situation warrants, we can give a concrete example of
    possible errors/bugs to a developer. Dial-in is still an option, but to be
    able to look at the TOOL code, database setup, etc. without the limitations
    of dial-up may be faster and more efficient. Please let me know if you can
    provide this, as well as the answers to the above questions, or if you have
    any questions.

    We did that trick already.
    When it is hanging, I can see what is doing.
    It is doing OPEN CURSOR. But not clear the exact statement of the cursor
    it is trying to open.
    When we run the query directly to Sybase, not using Forte, it is clearly
    not opening any cursor.
    And running it directly to Sybase many times, the response is always
    consistently fast.
    It is just when the query runs from Forte to Sybase, it opens a cursor.
    But again, in the Forte code, Alex is not using any cursor.
    In trying to capture the query,we even tried to audit any statementcoming
    to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

  • Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

    Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

    Thanks Kelly,
    The answers would be the following:
    1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
    Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
    The cells will be numeric, free text, drop downs, and some calculated numeric.
    Are we reaching the limits for UI performance?
    Thanks

  • IOS 8.1+ Performance Issue

    Hello,
    I encountered a serious performance bug in Adobe Air iOS application on devices running iOS 8.1 or later. Approximately in 1-2 minutes fps drops to 7 or lower without interacting with the app. This is very noticeable in the app. The app looks like frozen for about 0.5 seconds. The bug doesn't appear on every session.
    Devices tested: iPad Mini iOS 8.1.1, iPhone 6 iOS 8.2. iPod Touch 4 iOS 6 is working correctly.
    Air SDK versions: 15 and 17 tested.
    I can track the bug using Adobe Scout. There is a noticeable spike on frame time 1.16. Framerate drops to 7.0. The App spends much time on function Runtime overhead. Sometimes the top activity is Running AS3 attached to frame or Waiting For Next Frame instead of Runtime overhead.
    The bug can be reproduced on an empty application having a one bitmap on stage. Open the app and wait for two minutes and the bug should appear. If not, just close and relaunch the app.

  • Returning multiple values from a called tabular form(performance issue)

    I hope someone can help with this.
    I have a form that calls another form to display a multiple column tabular list of values(needs to allow for user sorting so could not use a LOV).
    The user selects one or more records from the list by using check boxes. In order to detect the records selected I loop through the block looking for boxes checked off and return those records to the calling form via a PL/SQL table.
    The form displaying the tabular list loads quickly(about 5000 records in the base table). However when I select one or more values from the table and return back to the calling form, it takes a while(about 3-4 minutes) to return to the called form with the selected values.
    I guess it is going through the block(all 5000 records) looking for boxes checked off and that is what is causing the noticeable pause.
    Is this normal given the data volumes I have or are there any other perhaps better techniques or tricks I could use to improve performance. I am using Forms6i.
    Sorry for being so long-winded and thanks in advance for any help.

    Try writing to your PL/SQL table when the user selects (or remove when deselect) by usuing a when-checkbox-changed trigger. This will eliminate the need for you top loop through a block with 5000 records and should improve your performance.
    I am not aware of any performance issues with PL/SQL tables in forms, but if you still have slow performance try using a shared record-group instead. I have used these in the past for exactly the same thing and had no performance problems.
    Hope this helps,

    Hi shubhu,
    I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
    Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
    Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.
