Performance analysis -1

Major reasons for the performance issues:
1. Long running programs may cause system bottlenecks
2. High utilization of cpu (ST06)
3. High utilization of RAM (ST06)
4. High utilization of i/o (ST04)
5. High utilization of Network (ST06)
6. Configuration (Memory / buffer) configuration.

Who are responsible for performance tuning:
  1. BASIS Consultant.
  2. ABAP Consultant.

BASIS tuning:

1. Optimize system parametrs
    - R/3 paramters (for example, No. of dialog workprocess).
    - Database parameters (for example, Database buffer sizes).
    - Operating system
    - network parameters
2. Optimize database disk layout through I/O balancing.
3. Optimization of workload distribution
    - Number of workprocess
    - Number of background process
    - log -on groups
4.Verify hardware sizing by detecting hardware bottlenecks
