    Performance Issue with JBP2.7.1; Any workaround??

    vivek saini Newbie

      I observed that Hibernate layer is firing unnecessary queries to DB. This is observed in getPortal(String name) method of ContextImpl class.
      This method called from getDashboard(User user) method of CustomizationManagerService.

      I put following sop in getPortal(String name) method.

       public Portal getPortal(String name)
       {
       System.out.println("before getChild(name);===>");
       PortalObject child = getChild(name);
       System.out.println("After getChild(name);===>");
       if (child instanceof Portal)
       {
       return (Portal)child;
       }
       return null;
       }
      


      and these are the logs from server

      So in this following query is being fired repeatedly.

      select portalobje0_.PK as PK10_0_, portalobje0_.LISTENER as LISTENER10_0_, portalobje0_4_.INSTANCE_REF as INSTANCE2_18_0_, case when portalobje0_1_.PK is not null then 1 when portalobje0_2_.PK is not null then 2 when portalobje0_3_.PK is not null then 3 when portalobje0_4_.PK is not null then 4 when portalobje0_.PK is not null then 0 end as clazz_0_, declaredpr1_.OBJECT_KEY as OBJECT1_2_, declaredpr1_.jbp_VALUE as jbp2_2_, declaredpr1_.NAME as NAME2_, modes2_.PK as PK3_, modes2_.name as name3_, windowstat3_.PK as PK4_, windowstat3_.name as name4_ from JBP_PORTAL_OBJECT portalobje0_ left outer join JBP_CONTEXT portalobje0_1_ on portalobje0_.PK=portalobje0_1_.PK left outer join JBP_PORTAL portalobje0_2_ on portalobje0_.PK=portalobje0_2_.PK left outer join JBP_PAGE portalobje0_3_ on portalobje0_.PK=portalobje0_3_.PK left outer join JBP_WINDOW portalobje0_4_ on portalobje0_.PK=portalobje0_4_.PK left outer join JBP_PORTAL_OBJECT_PROPS declaredpr1_ on portalobje0_.PK=declaredpr1_.OBJECT_KEY left outer join JBP_PORTAL_MODE modes2_ on portalobje0_.PK=modes2_.PK left outer join JBP_PORTAL_WINDOW_STATE windowstat3_ on portalobje0_.PK=windowstat3_.PK where portalobje0_.PK=?


      The no. of times this query gets fired is equal to no. of children of dashboardContext in Database.

      I used following query to know the no. of children of dashboardContext in Database.
      select count(*) from JBP_OBJECT_NODE where PARENT_KEY=8
      


      It's true that these query gets fired only first time of method call. All subsequent data comes from cache.

      But It is a performance issue since suppose there are thousands user dashboard, then this query will be fired thousands time before end user see his Dashboard first time.

      Is there any workaround??

          You should try the project trunk or EPP 4.3 CP01, there was some fixes in that domain

            Thank you Thomas !!

            I will try to checkout from SVN trunk and come back with results.

            Again thanks a lot.

                JBoss-portal-2.7.2-GA Notes says,

                * [JBPORTAL-2281] - Perf issue when many user dashboard

                is it the same issue we are looking to, have some one verified for the scenario mentioned by Vivek with latest 2.7.2?

                  So no call to db, picking nodes from cache. Now compare the results with my previous tests (posted before this with SVN code),
                  If we were getting nodes from cache, the time taken was always 0 to 1 milli seconds, its now consistently
                  4-5 milliseconds(If there will be 10000 dashboards, perfromance will be pretty poor even if we get from cache)


                  Any thoughts to avoid this, or should go with SVN code..

                    This issue should be fixed in subversion. Can you please give a try to the latest revision and let us know how it works for you?

                      Hi Chris & Thomas,


                      We build portal-core-lib.jar from SVN and deployed it in our setup. Problem got resolved by this, although we got surprised by addition of two new methods in CustomizationManager interface since we have our own implementation for CustomizationManagerService.

                      Thank you for quick reply and resolution of problem.

                        Ah, sorry about that. Then again CustomizationManager is not part of the public API... :)
                        May I ask why you need your own implementation?

                          Hi,

                          Actually we wanted to have different dashboards for different group of users.
                          In this scenario a Manager can define dashboard for his team members. The end user will only see pages/portlets on his dashboard, which ware assigned to him by his manager. End user can also have his private pages.

                            Yes. This is something like what we would want to have. Is there an out of the box solution to grouping collections of users and having a group admin? The group admins should have a definable subset of responsibilities assigned by the uber admin to administer their group or community.

                              The following is the reason for writing a custom implementation:

                              we wanted to assign a set of pages with a set of portlets to a user group.

                              So, we wanted to have different user groups and then assign each group a set of pages and give them personalization feature to add more pages of their choice.

                              We can do this by writing a MBean like CustomizationManagerService, with following logic for getDashboard, method:

                              Find the group of user, get what all pages (with what all portlets) needs to be there for that user group, Add everything on dashboard of the user.

                              Will like to have your views on this design..from JBP point of view..will it be a performance hit..(even if i use the SVN fix :-) )
