8 Key Performance Metrics Quality Assurance or Performance calibration Does a platform meet performance requirements? Are vendor's performance numbers achievable? Are there any performance bottlenecks in the platform, which have impact to application performance? Does the platform at least deliver the same performance after the system change?

9 Key Performance Metrics Platform evaluation Which platform delivers best price-performance ratio, taking into consideration Oracle license costs? How to get adequate figures in a short time for management decisions? Application(s) Middleware Database System 1,0 1,0 1,1 2,5 0,7 2,1 Price Performance DataGuard Network Fusion I/O Interconnect File System Volume Management Operating System Server Virtualization Storage System Storage Network Current System New System A New System B copyright 2014 by benchware.ch slide 9

10 Key Performance Metrics Capacity planning What are the performance limitations of a platform? How much of the resources are already utilized? How much reserve of resources is still available?
