7. Ideal Condition
CPU
Utilization ≤ 70%
Memory
Machine Pool Fault ≤ 10 faults/sec
Disk
Space Utilization ≤ 70%
Arm Utilization ≤ 30%
The above threshold for machine’s ideal condition is based on IBM’s performance analysis best practice.

11. Performance Analysis
• CPU Utilization ≤ 70
• Jam operational: max 40-50%
• Batch process: max 71.8%
• Machine Pool Faults/sec ≥ 10
• Max 99 fault/sec → kekurangan memory
• Disk arms utilization ≥ 30
• Jam operational: max 20%
• Batch process: max 57.4% → disk arms kurang banyak atau
efek kekurangan memory
• Disk space utilization ≥ 70
• Disk space utilization → 73.1%
• Perlu dilakukan housekeeping atau penambahan disk

12. Considerations
• Tidak bisa menambah memory → sudah withdrawn
• Tidak bisa menambah disk dan disk expansion →
sudah withdrawn
