In a traditional multitier applications performance bottlenecks can be in user interactions level or network latency or data access or business logic level. The solutions as changes or tuning parameters can be applied at architect, design, framework or algorithm or at coding level. This paper highlights an inquisitive, experimental, top down, tear apart, drill down and analytical approach across two aspects one across end to end process flow and data flow on those specific use cases or scenarios requiring performance improvement and another across layers of abstraction like architecture, framework, design, logic and coding. Re engineering for performance gain requires identifying hot spots on both aspects viz which architectural, design decision or which processing or data flow stage is having performance issue.
