    The function of DISP+WORK service :

    Disp means Disptcher and Work means Workprocesses.

    When user typed userid and password in GUI, userid will be in disp[tcher queue.

    Dispatcher check whether any work processes (dialog process) are free or not. if any workprocxess (dialog) is free then dispatcher allocate userid to that dialog process. otherwise userid will remin in dispatcher queue.

    As you have mentioned that disp+work is busy. This could be due to the reason that your workprocesses (either dialog or background processing) is running .

    check the corresponding PID with sm50 and note down the report name and user who casues the processing high.

    Inform the user regarding the tyransaction and if possible fine tune program.

    Surely it will busy whenever user tries to request something in SAP this service is responsible to handle the user request and distribute to SAP "Workprocess" (WP) i.e DVEBMGS.

    Hello,

    Go to SM50 when disp+work is hanging or busy

    See which work process is in red or with error

    Open the corresponding work process trace file for this work process.

    use ST11 to see trace files open the work process file and see what errors you

    have.

    regards,

    John Feely

    Hi,

    As John already stated, goto SM50 and search for the process ID. You can then see what the current action and or report is. You can then execute a work process or user trace in ST12 or SE30 to see what's contributing to the high CPU usage.

    Hope this helps...

      Hello Silva,

      What type of application is that. BW / ECC / SCM / Portal / SRM etc.

      Based on the type ABAP / JAVA / ABAP + JAVA Stack also considering corresponding OS & Database need to start your analysis.

      Also let us know if the performance is

      Always Slow or Slow only in specific scenario or Sudden Slow or it's Sporadic.
