• Check applications for possible bottlenecks.
• Examine the data communications environment for sources of trouble.
• Analyze the system hardware to determine if it provides an optimum configuration.
For system tuning, you need to keep in mind that GPA is meant to serve mainly as a
guide and to provide a quick and convenient performance analysis. For the best long-
term solutions to system performance problems, you need to have properly trained
personnel do a careful and detailed analysis.
The Detail System Performance Score Reports
The Detail System Performance Score Reports provide more detailed information
about how GPA rates the performance of a node and its subsystems, and how it
derives the final scores in the System Performance Score subsection of the System
Performance Summary. The Detail System Performance Score Reports consist of the
following ten subsections:
• Negative Contributing Factors to CPU Score
• Negative Contributing Factors to Memory Subsystem Score
• Disk Cache Performance Score Grading
• Negative Contributing Factors to Disk Volume Score
• System Recovery Performance Score Grading
• CPU Failure Simulation
• Server Process Analysis for the Individual CPUs
• Dynamic Server Process Analysis
• Disk Cache Change Analysis
• CPU Cache Change Analysis
Example 4-35 is a cover page for the optional System Performance Score Reports. In the
example, detailed sections are requested for each score.
