Question

Hi,
I'm working on Stellent 7.5.1.
For one of the portlet in portal its taking more time to fetch data. Please can some one help me to solve this issue.. So that performance can be improved.. Please kindly provide me solution.. This is my code for fetching data from the server....
public void getManager(final HashMap binderMap)
throws VistaInvalidInputException, VistaDataNotFoundException,
DataException, ServiceException, VistaTemplateException
     String collectionID =
getStringLocal(VistaFolderConstants.FOLDER_ID_KEY);
     long firstStartTime = System.currentTimeMillis();
HashMap resultSetMap = null;
String isNonRecursive = getStringLocal(VistaFolderConstants
.ISNONRECURSIVE_KEY);
if (isNonRecursive != null
&& isNonRecursive.equalsIgnoreCase(
VistaContentFetchHelperConstants.STRING_TRUE))
VistaLibraryContentFetchManager libraryContentFetchManager =
new VistaLibraryContentFetchManager(
binderMap);
SystemUtils.trace(
VistaContentFetchHelperConstants.CONTENT_FETCH_TRACE,
"The input Parameters for Content Fetch = "
+ binderMap);
          resultSetMap = libraryContentFetchManager
.getFolderContentItems(m_workspace);
* used to add the resultset to the binder.
addResultSetToBinder(resultSetMap , true);
else
     long startTime = System.currentTimeMillis();
* isStandard is used to decide the call is for Standard or
* Extended.
SystemUtils.trace(
VistaContentFetchHelperConstants.CONTENT_FETCH_TRACE,
"The input Parameters for Content Fetch = "
+ binderMap);
String isStandard = getTemplateInformation(binderMap);
long endTimeTemplate = System.currentTimeMillis();
binderMap.put(VistaFolderConstants.IS_STANDARD,
isStandard);
long endTimebinderMap = System.currentTimeMillis();
VistaContentFetchManager contentFetchManager
= new VistaContentFetchManager(binderMap);
long endTimeFetchManager = System.currentTimeMillis();
resultSetMap = contentFetchManager
.getAllFolderContentItems(m_workspace);
long endTimeresultSetMap = System.currentTimeMillis();
* used to add the resultset and the total no of content items
* to the binder.
addResultSetToBinder(resultSetMap , false);
long endTime = System.currentTimeMillis();
if (perfLogEnable.equalsIgnoreCase("true"))
     Log.info("Time taken to execute " +
               "getTemplateInformation=" +
               (endTimeTemplate - startTime)+
               "ms binderMap=" +
               (endTimebinderMap - startTime)+
               "ms contentFetchManager=" +
               (endTimeFetchManager - startTime)+
               "ms resultSetMap=" +
               (endTimeresultSetMap - startTime) +
               "ms getManager:getAllFolderContentItems = " +
               (endTime - startTime) +
               "ms overallTime=" +
               (endTime - firstStartTime) +
               "ms folderID =" +
               collectionID);

Hi.
The Select statment accessing MSEG Table is Slow Many a times.
To Improve the performance of  MSEG.
1.Check for the proper notes in the Service Market Place if you are working for CIN version.
2.Index the MSEG table
2.Check and limit the Columns in the Select statment .
Possible Way.
SELECT MBLNR MJAHR ZEILE BWART MATNR WERKS LIFNR MENGE MEINS
EBELN EBELP LGORT SMBLN BUKRS GSBER INSMK XAUTO
FROM MSEG
INTO CORRESPONDING FIELDS OF TABLE ITAB
WHERE WERKS EQ P_WERKS AND
MBLNR IN S_MBLNR AND
BWART EQ '105' .
Delete itab where itab EQ '5002361303'
Delete itab where itab EQ  '5003501080' 
Delete itab where itab EQ  '5002996300'
Delete itab where itab EQ '5002996407'
Delete itab where itab EQ '5003587026'
Delete itab where itab EQ  '5003587026'
Delete itab where itab EQ  '5003493186'
Delete itab where itab EQ  '5002720583'
Delete itab where itab EQ '5002928122'
Delete itab where itab EQ '5002628263'.
Select
