XIr2 Recommended Performance Tuning

XIr2 Recommended Performance TuningPerformance Tuning DefinedPerformance tuning is the improvement of system performance. The motivation for tuning can be real (its slow now) or anticipated (adding users).As load increases, performance decreases.The ability to accept a higher load is called scalability

Systematic TuningSystematic tuning follows these steps:Assess the problem and establish numeric values that categorize acceptable behavior. Measure the performance of the system before modification. Identify the part of the system that is critical for improving the performance. This is called the bottleneck. Modify that part of the system to remove the bottleneck. Measure the performance of the system after modificationUniverse DesignA separate discussion on optimizing SQLFollow best practicesUse Indexes, aggregates, shortcuts, etc.Apply row and time limitsTrain your users on not only how to build reports, but how to use specific universesReport Efficiency and Schedules Verify reports are built according to best practices (you do have these?)Your BI Center of Excellence can helpAudit the system for report usage, etc.Can some reports be scheduled?Audit the report schedulesDatabase resources / data modelsDB server percent utilization?What else is running on it?Is the data model for OLTP or queries?Indexs?Extra summary tablesNumber of DB connectionsRepositoryMove the repository to a separate serverFor the DatabaseFor the File StoreSplit Web and Application ServersAre you running Tomcat standalone?If yes, then add an HTTP server.This lets the application server focus on what it is good at, code translation, and lets the HTTP server handle HTML and image requests.Put each on separate serversTurn off IIS if not in use.Add another Tomcat instanceAdd another Tomcat instanceFor failoverTo maximize server memory (Tomcat has a max of 1024MB JVM)

Use Server GroupsServer groups can be used to direct report processing to a specific set of servers Organizes servers into sub-groups that can be managed and used independentlyDedicate resources to a particular set of users and/or applications
