Application response too slow- How to resolve (webLogic)

Hi All, Can you please let me know what are all the main areas that i need to concentrate in the weblogic application server if i get the complaint from the clients saying "application performance is too slow".
Edited by: user11361691 on Apr 21, 2010 12:18 AM

you need to check the following:
1: Check the server log files to find any errors at the time when the Client is complaining about the server performance.
2: You can enable the GC logs in the server log and can check whether the there is any issues with the memory usage of the server. From the GC logs you can that whether the time has been taken to to the GC and hence you can try allocating higher memory or you can try changing the GC algorithm according to the analysis.
For details refer the following link:

http://download.oracle.com/docs/cd/E13222_01/wls/docs100/perform/JVMTuning.html
3: Finally you can collect the thread dumps snap shots and can see whether there are any stuck threads or deadlock situation in the server at the time of slow performance.

  • TP Yoga 15 - Windows: Keyboard response too slow after coming back from hibernation

    I've got the same issue as outlined in this thread for a Y50 - there seems to be a BIOS update to solve it, but what about TP Yoga 15? Quote:Simply put, In keyboard properties , the Repeat delay is default at maximum (eg, holding down a keyboard button and how fast it generates the key strokes). When the system is put in hiberanation, then turned on again to come back, the Repeat delay some how gets decreased to about 2/3 of what it originally is. https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Re-Y50-Windows-8-Keyboard-response-too-slow-after-coming-back/td-p/1676309/page/1 

    hi guys,
    Can you please provide also these additional information:
    (this is to check if the issue is isolated to a certain model number)
    Model Number (eg. 59-xxxxxx): 
    Place of Purchase (eg. Amazon, Bestbuy, etc.): 
    In addition, the solution from this thread seems to be a good workaround (the app is for Win7 but may also work for Win8.1)

    When my application running, some of CPU have IDLE state = 0 and hold the CPU while another CPU have IDLE state 100. I think this is my bottleneck but I cannot find any solution for solve that.

    Why would anyone spend the time to try to give help that you have already received elsewhere? That's a waste of their time.

    Hey everyone in Apple world!
    I figured out how to fix the flashing yellow screen problem that I've been having on my MBP!  Yessssss!!!
    I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
    I followed the instructions on this page and here's what I did:
    Resetting NVRAM / PRAM
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process.  Since I did that, my MBP boots up just like normal.  No flashing yellow screen anymore!!   
    (Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
    Let me know if this works for you!

    Check your web server's access logs to see how many requests web start is sending for each jar. After you've loaded the application the first time, for each subsequent launch, if you've got everything configured right, you should only see requests for the JNLP file and maybe some gifs because web start should load everything else out of the cache (if you're using the version-based download protocol). Or if you're using the basic download protocol, then you might see requests for each jar file, but even in this case, if your web server is prepared to evaluate the last-updated attribute for each jar request and for jars that have not changed, respond with no actual payload and a header value of Not-Modified, then that should run almost as fast.
    You might also want to consider changing the "check" attribute of the "update" element from "always" to "background" for a couple of reasons. It should allow your app to start sooner (but this means that you might have to launch once or twice after an update is applied to the web server before the update shows up on the workstation). Also, my impression is that "always" is broken and prevents web start from ever checking to see if your jnlp file has been updated if you launch your app from a web start shortcut - launching from a browser is less likely to have this problem, depending on how often your browser is configured to check for updated resources.

  • Application running too slow on Sun SPARC T5440 but run normal on sun T5220

    Hi all,
    I have application running on sun server T5440 1.4 GHz, 95 GB RAM, 32 cores(s), 256 logical (virtual) processor(s), application is running slow on load. when I install my application on another server SPARC-Enterprise-T5220 (UltraSPARC-T2 (chipid 0, clock 1165 MH) , 8GB RAM, 1 core, 8 virtual processors ), application runs smoothly.
    Could anyone please help me out what could be the possible reason for this behavior as ideally it should give better performance on T5440 server.

    There is no need to duplicate what is happening there, particularly since you continue to refuse to mention your other web postings (very bad forum manners).   If no one knows what you have posted elsewhere they will probably waste their time duplicating what you have already been told.   No one here is paid to type a response.   This is a user-to-user community forum site. 

  • Encoder movement response too slow

    I have a USDigital QSB-D USB/serial encoder which uses a serial uart interface at 230.4 kb/s, 8 bits, no parity, 1stop bit.  The USDigital driver (USDQSB.dll) allows me to open/close and read/write to registers and provides get/set functions to set specific modes.  The driver provides StreamEncoderCount function which takes threshold and intervalRate parameters.  The threshold specifies count changes to trigger transmission and the intervalRate is time interval between transfers.  In the attached VI I am attempting to use the StreamEncoderStatus() function to wait for the encoder index pulse which indicates the encoder has passed zero counts.  When the index pulse is detected I would like to use the StreamEncoderCount function to retreive encoder counts as rapidly as possible.  I am setting the threshold to 0 so it will read the count even if it is not moving and intervalRate to 1 which should be sending count value at 1.9 msec intervals.  The for loop count ie 100 which should take 190 msec to read at 1.9 msec.  The for loop takes over 3 sec which means that the sample rate is over 30 msec instead of 1.9 msec. I am using a notification to notify another the other while loop which plots the results.  Everything works as intended except for the slow response of 30 msec per sample instead of 1.9 msec.

    QSBEncoder2.vi ‏72 KB

    I was not able to find your dll benchmark application to do that test but I am beyond that now.  I have found the correct function to read streamed serial input from the encoder which is the USDQSB.dll function: GetCountWithTimeStamp() which apparently just reads the streamed serial input and does not query the count register repeatedly.  The attached QSBEncoder3.vi uses that function and performance is as expected.
    I have rewritten the encoder application to use the VISA driver.  The encoder is automatically recognized as a serial device by VISA and assigned the instrument ID: ASRL3::INSTR.  The attached QSBEncoder4.vi attempts to access the encoder using VISA but I don't get any response from the encoder serial port.  Any ideas on what I am doing incorrectly?  I am able to access the encoder using the VISA interactive control but when using the LabView QSBEncoder4.vi application I don't see any input coming from the ASRL3::INSTR  device.

  • My swing application is too slow

  • Imac is way too slow-how can i speed it up

    I have been using my imac for over four years. Recently. it has really started to slow down.
    How can i run a diagnostic test to know what the problem is?

    Download, install and periodically run AppleJack[url]. This calls several unix routines including those which repair your directory and disk permissions, and cleans out extraneous cache and corrupted preference files.
    Consider reapplying the current combo updater for your OS. For Mac OS X 10.4.11, the intel package is available [url=http://support.apple.com/downloads/MacOS_X_10_4_11_Combo_Update__Intel]here. You must use this larger Combo updater and not the smaller Delta one to impact this issue.
    Consider reinstalling Safari 4.04 which is likely responsible for much of your perception that the machine is 'running slowly.'

    I also have this problem.

    Model: 20378
    Purchase from: Replacement/Exchange from Lenovo
    I wish I saw this thread before I did a factory restore. Ohh well, atleast its somewhat comforting to know I'm not the only one having this issue. I initially blamed the problem on my Razer Orochi 2013, but turns out that wasn't the issue.
    And I agree a proper fix is needed, wether is be some kind of BIOS or Driver update, but not some 3rd Party work around. For a $1,200+ laptop, this shouldn't be something that just get's swept under the carpet with a "temporary fix".
    Please keep us up to date on the status of this issue Lenovo.
    EDIT: Using this post as the first in the thread for escalation purposes - Amy_Lenovo

    When I put the Y50 to sleep or hibernate and then wake it, the keyboard refresh rate defaults to incredibly slow speeds.  So when I hit and hold backspace, it only removes 3 characters a second as opposed to 15-20 per second like I desire.  The only solutions are to reoboot or go into keyboard settings in the control panel and save the settings again.  The settings don't actually change, so just opening the settings and hitting apply is good enough to fix it.  This is obviosuly a software bug and others on online forums are experiencing the same issue.  If anybody else is experiencing this bug, please post here so Lenovo might take action to correct it faster.  Lenovo, if you're listening, please offer us a solution.

  • Database slow; How to check the Oracle query timings

    Hi,
    I have a quick question regarding a troubleshooting iam currently working on.
    We have a J2EE application runnig on WLS 81 SP3.
    We are experiencing a problem where the customer response time on our application is "too slow". We checked our N/W and they seems to be OK. The Iplanet webserver and BEA application servers looks good but on the Oracle database box - i saw "iowait" (when doing top UNIX command) to be 50-60 % which is extremly high. We are suspecting this to be our issue as the "iowait" is very high at the DATABASE box hence causing BEA servers to show "slow response" on certain pages which are database accentric.
    Now, in order to proove that the queries are taking "too longer" to execute from the time BEA server requested and it actually got the reply back from database, i need to dig down and get some "profiling" (due to some political reasons, i can request to turn on profling at the moment) done. So, is there any way i can verify the response time when the BEA server requested some information from the database and the time when Oracle database responded with all the information requested ?
    thanks for your help,

    Yes. Create a Date object prior to the database call. Then create another one when the call completes. Convert both to mililseconds and subtract. You will have network latency in that statistic, but especially if you are using connection pools, the vast majority should be database access.
    Another option is to turn on tk_prof or create an EXPLAIN plan table in Oracle. That will show the 'cost' of each query. Also, try running statistics on the database, that should help the optimizer.
