Performance issue in CrystalReportViewer.processHttpRequest(), Java SDK

Question

Hi,
We are using BOXI R2 sp3. We have a schedular which schedule the reports on daily basis and create the file on boxi server. These reports are shown to the user on web UI through jsp. Below are the steps I am following while showing the report on UI:
1) Create the IEnterpriseSession object for the user session and save it for future use.
2) Get a reference to the IReportSourceFactory using EnterpriseSession.GetService(u201CPSReportFactoryu201D).
3) Open the report source using IReportSourceFactory.openReportSource(<report id>, Locale) call.
4) Create the CrystalReportViewer object and set the report source in it. Below I am showing all the settings for crystal report viewer object.
      CrystalReportViewer reportViewer = new CrystalReportViewer();
      reportViewer.setEnterpriseLogon(es);
      try {
     reportViewer.setReportSource(reportSource);
      } catch (ReportSDKExceptionBase e) {
     logger.log(Level.SEVERE, "", e);
      reportViewer.setDisplayPage(true);
      reportViewer.setDisplayGroupTree(false);
      reportViewer.setDisplayToolbar(true);
      reportViewer.setOwnPage(true);
      reportViewer.setHasViewList(true);
      reportViewer.setHasLogo(false);
      reportViewer.setHyperlinkTarget("_blank");
      reportViewer.setHasRefreshButton(false);
      reportViewer.setEnableDrillDown(true);
5) Call processHttpRequest() function on crystal report viewer object to display the report on UI.
These steps works fine in order to display the report on UI but the issue I am facing is related to time. This entire process is taking almost 1 minute to display 10,000 pages of reports which is not acceptable in our case. This time delay is happening for first time when user is viewing the report since later it is being served from cache but problem doesn't get resolved using cache. The cache size is limited and we have lot of these kind of reports so cache will get swapped often.
I tried debugging the above code and found that processHttpRequest() call itself takes 55 seconds. Could anybody tell me what this function is doing internally and why it is taking so much time.
My manager is thinking to get rid of crystal reports because of this issue and develop our own custom solution. Please provide any help if anybody knows about it.

Answer 1

I found some more query in code after digging up further:
After getting the folder id, We execute the below query to display list of all avaialble reports on the server
Select SI_ID, SI_NAME, SI_LAST_RUN_TIME From CI_INFOOBJECTS Where SI_PROGID='CrystalEnterprise.Report' And        SI_INSTANCE=0 AND SI_PARENTID = "     + serverDao.getReportFolderID(iSession) + " ORDER BY SI_NAME
The SIID returned for a report from above query is passed to get all the instances for it in another query, which is mentioned below:
Select * From CI_INFOOBJECTS Where SI_PROGID='CrystalEnterprise.Report' AND SI_INSTANCE=1 AND SI_SCHEDULE_STATUS=1 AND SI_PARENTID = " + SI_Identifier + " ORDER BY SI_ENDTIME DESC
This query returns me the list of instances with SIID. Finally this SIID is used to get the content. I hope this answer your query.
Also I tried the crystal interactive viewer yesterday but found no difference in performace. Could you tell me how exactly we can use the interactive viewer.
