Few calculation for Performance tuning

1. R/3 workload monitor (ST03N)       

                  wait time > 10% of response time

                        Solution: General performance problem, can ignore.
       2.High database time: database time > 40%(response time- wait time)
                        Solution: detailed analysis of the database
       3.Processing time > cpu time *2
                        Solution: Detail analysis of hardware bottlenecks
       4. load time > 50 ms
                        Solution: Detailed analysis of R/3 memory configuration( is the program buffer too small?)
       5. Roll- wait time or GUI time > 200 ms
                      Solution: Detailed analysis of interfaces and GUI communication
                                                   -->OS logs.

      6. T-code OS06-->  for network speed check.
