System Performance Score
This subsection of the report (Example 3-4) rates the performance of the node and its
subsystems from 0 to 100%, with a score of 100% being best. Note that these scores
are not absolute values. They merely indicate the quality of performance of the
subsystems and show which of the subsystems might profit from corresponding tuning
changes.
The system recovery performance score indicates how well the system would be able to
continue performing if any of the processors were to fail.
The weighted analysis system score is a weighted average of the subsystem scores. If
GPA finds that either the CPU or memory subsystems have a performance score of
1% or less, it assigns a value of 1%. In these cases, the weighted analysis system
score is set to 1% also.
The individual scores are detailed in The Detail System Performance Score Reports in
Section 4: Using GPA Information .
Example 3-4. System Performance Score
IV. SYSTEM PERFORMANCE SCORE
1. CPU SUBSYSTEM 1%
2. MEMORY SUBSYSTEM 1%
3. DISK CACHE SUBSYSTEM 83%
4. DISK VOLUME SUBSYSTEM 9%
5. SYSTEM RECOVERY PERFORMANCE 52%
*6. WEIGHTED ANALYSIS SYSTEM SCORE 1%
* Average Score rated: BEST = 100, WORST = 0.
