J2EE data retrieval slow! Is this normal??

Using Sun Server 8.1
I have an entity bean called taglist. Taglist has six 1:1 relationships and one 1:Many relationship. When running the finder "select * from tagList where subId = ? order by tagListId" I get about 85 taglist rows of data back and about 500 rows from foreign key tables. The references come back instantaneously but when I try to put the data into valueObjects it takes about 16 seconds. If I just get the data straight from the local interfaces when I need it it still takes around 16 seconds.
Is this normal? Is there anything I can do to improve performance? Any suggestions will be greatly appreciated.
Thanks!

Did you enable relationship prefetch? As your query selects Taglist entities only, relationship fields should not be instantiated otherwise. Fetching the relationships after the query might take some time, but it shouldn't take 16 sec. to fetch 500 instances.
Please try enabling the logger for the "jdo" module and see what queries are executed by the server.
Is "sudId" the foreign key for the 1:Many relationship?

  • When i installed yosemite on my mac book it runs very slow, is this normal ?

    After installing OS X yosemite on my mac book it runs extremely slow. Is this normal ?

    Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
    Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
    Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.

  • Airport Express downloads SLOW - is this normal or do I have a problem?

    I have a DSL modem connected to an Airport Express and my two Macs (G4 Quicksilver and G4 iMac) are connected wirelessly ( Airport card in the old computer, Airport Extreme in the iMac). Internet downloads are crawling, so I used several DSL speed tests on the iMac from the net, getting download speeds from 62 - 108 kbps. I called my ISP (Mindspring) and they asked me to check connecting the modem directly to the iMac by Ethernet. Now the downloads are going at the rate I'd expect, 1100 - 1300 kbps.
    Is this loss of speed using wireless conections, with 2 computers going, expected with the Airport Express, or is there a way to get better results? Note that signal strengths are good.

    However only 2 speakers will work no matter what I am doing unless I turn on the CMSS 3D setting in the EAX console.Only then will all my speakers work.
    However if the CMSS 3D setting is off I can go into the Speaker Settings console and run the channel tester and the noise button and it plays the sound in all of the speaker channels including the woofer.But when I play music or any games it only uses the front left and right speakers as if it were only a stereo set of speakers and not a 5..But turn on the CMSS 3D again and I get full 5. sound in all speakers the way it is supposed to be.
    Normal. Nothing worng with it.
    As for Ventrilo, no idea cos I don't use that.

  • New connection very slow - is this normal ?

    Hi
    I just had option 3 broadband installed today but seem to be stuck on an IP profile of 2 Mbps. It was supposed to be 6-8, probably 7 Mbps.
    The line is clean and I tried the quiet line and it was very quiet.
    I understand there's a 10 day bedding in period, but wouldn't it start high and go down from there ?
    How long will I have to wait at 2 Mbps ?

  • Slow data retrieval on 8i

    I am using oracle 8i database on Windows 2000 server on compaq
    proliant 350 server machine. The problem is that sometimes
    connecting from a client is very slow and after connection data
    retrieval is also slow. I am usring TCP/IP and net8. I came to
    know from internet that there is a patch which is actually a
    work around to solve this problem. Can anybody help me to locate
    this patch?
    Thanks in advance.
    G. Rajan.

    You can probably prove that this is the issue by creating a retrieve using the excel addin or smart view to replicate the form and see how long it takes to retrieve.
    You will also see in the essbase app logs how long it is taking to perform the retrieve.

  • Logical reporting cube - slow data retrieval

    OLAP 11.2
    I have seen discussion on this board recommending using a logical reporting cube to expose data if there are multiple physical cubes in the workspace.  The problem I am having is that the data retrieval seems very slow from the logical cube while it is fine if I select from the actual physical cubes. Here is my set up.
    Physical cube A - Dimensions x,y,z
    Physical Cube B - Dimension w,x
    Physical Cube C, Dimension y,z
    Logical Cube  D. Dimension w,x,y,z with calculated measures mapped to the measures from the cubes A,B and C as well as some other calculated measures based on these.
    Data retrieval from A, B and C is quick but the query hangs if I select certain measures from D. On some measures, it seems to work without issues.
    Is there some thing I am missing?
    Thanks,
    Usman

    Usman,
    Its probably because of LOOP_VAR  and/or LOOP_DENSE settings of the measures in your Logical reporting cube.
    I have posted on this topic in the past.   With this new Oracle-Forum interface its difficult to search old postings.
    (1). Execute the following:
    exec dbms_cube_log.enable(dbms_cube_log.TYPE_OPERATIONS, dbms_cube_log.TARGET_TABLE, dbms_cube_log.LEVEL_HIGH);
    (2). Run the olap query.
    (3). Query CUBE_OPERATIONS_LOG table
    select *
    from cube_operations_log
    where   upper(suboperation) like '%LOOP%' or upper(name) like '%LOOP%'
    order by time;
    Tell us what you see in the 'NAME  and  'VALUE'  columns, after your query execution.
    Also take a look at this post:   Delay when querying from CUBE_TABLE object, what is it?

  • BPC 10 - EPM data retrieval very slow!

    Hi BPCers,
    We are using an Excel EPM Input Schedules as a Resource Management tool - using VBA to provide the functionality we need.
    Performance is generally good, but quickly deteriorates when handling larger data sets - even 500-600 rows of transactional data is enough to slow data retrieval from our BPC Cube to EPM to an unusable speed. This is in relative terms pretty small so  there should be some option for optimisation.
    Does anybody have any experience with this? All suggestions welcome. We are operating on EPM Service Pack 7 Patch 1, but I'm not sure that EPM is necessarily the problem here.
    Thanks,
    Tom

    Thanks Gersh,
    Had a look through fiddler and have identified the job that is causing the delay - some rooting around in the ABAP debugger produced the answer as to why adding more data slows processing speed so dramatically.
    When we take data from the back end, we select a couple of parameters which limit the range of data that we are pulling through - a certain set of people, and a certain range of days. Once this is pulled through, allocations are made to any combination of person and day within this range, which generates and extra two properties - a project ID and a work status.
    This makes 4 properties, and when BPC pulls data it attempts to find every combination of every one of the properties that exist within this range - so the more allocations made the more this slows down as it dramatically increases the number of combinations.
    The result is that BPC runs through a couple of hundred thousand generated tables, most of which are nonsense.
    Not sure what to do from here. This is how BPC reads data so approaching a fix could be difficult.

  • It goes so slow when I open my Mac, is this normal??

    hi, i don't know if any of you ever experienced this as well or not, but i don't feel happy with how it goes so slow when i open my mac.
    soo.. i just installed OS X Mavericks on my macbook pro 13" (2.4 GHz with memory 4 GB), since then it feels much slower for me to wait for my mac loading into the desktop screen, is it normal?? but i can work with the applications normally after it's opened, not even as slow as the opening part. is this normal too?? or should i downgrade the OS? what indicates that mac isn't compatible with the OS?
    i see some has posted that teir macs running slowly too after installing Mavericks, if you experience it too, is it the whole thing you do on your mac getting sloweer or only at the opening part as what's happening on mine?
    Thanks before!! Regards!

    I have same Problem. I tried all options - Reset All Settings, Erase Content & reset all settings, Upgrated to IOS8.1, Restore using iTune. But problem persists.
    When I turn Cellular Data or Wifi ON, then there is a lag while opening the Apps. But If I turn Data/Wifi off, phone becomes super fast. I have checked with my friends. They are not facing this issue. Not sure if Apple know this.

  • Upgraded from 10.6.8 to Mavericks last week on my MacBook Pro running the 2.4 GHz i5 and it's painfully slow on start-up- I mean, 5 minutes or more, to be fully functional... Is this normal?

    Upgraded from 10.6.8 to Mavericks last week on my MacBook Pro running the 2.4 GHz i5 and it's painfully slow on start-up- I mean, 5 minutes or more, to be fully functional... Is this normal?

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities 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.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    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 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.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

  • Slow wifi on mac book air.. is this normal? (airdrop)

    when using airdrop to send from mac book air (11 inch mid 2011) to a mac book pro (13 inch mid 2011) the wifi airdrop transfers seem very slow. a 5 gig file took 30 minutes to airdrop. when i was at my brothers house and i sent 11 gigs to his imac (unsure which model maybe 2009 <- before thunderbolt) it took 3 hours.
    i thought maybe this was airdrops fault, so i connected this mac book air to my mac mini (mid 2010) using airdrop, it also took 30 minutes for 5 gigs.
    so i made a manual WEP adhoc connection on channel 48, it also took 30 minutes for 5 gigs. i then tried copying files from another laptop (a dell)
    and the 5 gig file copied at the full 300 mbps (or abouts) maybe 5 minutes to the macmini
    whats going on here??? is this normal for the mac book air?? do i have a bum wireless card?? i was going to ask a genius to switch out the wifi card or check the antennas but i thought i would post here to see if anyone else has problems
    when copying to the mac book pro or the imac i made sure that both computers were connected at 2.4 to different networks, to make sure that 2.4 was
    tied up, figuring the simulataneous airdrop connection would prefer 5 ghz. ive seen it sometimes airdrop on the same machines on the same network and taking longer because it was a 802.11g network.

    seems like any of the 2 computers on at 2.4 ghz (even on different networks) slows down airdrop. but havingboth computers wifi cards on but not connected to anybody, speeds up airdrop dramatically.
    sending from air to mini (air = 5 ghz wifi) mini (2.4 wifi) airdrop speed 12 gigs in 1 hour
    sending from air to mini (air = 5 ghz wifi) mini (not connected) air drop speed 12 gigs less then 30 minutes
    sending from air to mini (both at 2.4 ghz) 4 hours
    sending from air to imac (both at 2.4 ghz on two different networks ) 4 hours

    Where can I find this new version?  Thank you
    10.7.4 is the latest update of MacOS X Lion. Run Software Update in System Preferences.
    Since you state to run 10.7.2, Software Update will have to use the combo updater to bring it up to 10.7.4. This will entail a large download that will take some time so have patience. I suggest the following steps:
    Restart the Mac, press and hold Command-R to start up in Recovery Mode (More info: http://www.apple.com/macosx/recovery/ ).
    If needed, select the desired language to move to the next screen (only if it is the first time in Recovery Mode).
    Select Disk Utility in the bottom of the list, Continue...
    Choose the hard disk drive device on the list ( xxx.xx GB APPLE HDD ...) by clicking on it.
    Click on Repair Disk button, wait for it to finish.
    Choose the Lion boot volume, Macintosh HD, by clicking on it.
    Click the Repair Disk button, wait for it to finish. If any errors are found and the process does not end with a "The volume Macintosh HD appears to be OK." message, click on Repair Disk again.
    Click on the Repair Disk Permissions button. This will take awhile to finish.
    Quit Disk Utilities, choose Restart from the menu.
    Now run Software Update in System Preferences, choose to apply all missing updates. This will take quite awhile, depending on how fast your Internet connection is. The Mac will need to be restarted when the updating is done.
    Run Software Update again to have Safari updated to the latest version. This is necessary since Safari 5.1.7 needs OS X 10.7.4 to be running already.
