CDS Performance Optimization 1

Question 1

What is the first step in performance optimization?

Accepted Answer

Establish baseline measurements and identify bottlenecks

Answer

Establishing baselines and identifying bottlenecks ensures optimization efforts target actual performance issues rather than assumed problems.

Question 2

Why is monitoring important for performance management?

Accepted Answer

It provides real-time visibility into system behavior and early warning of issues

Answer

Continuous monitoring provides real-time visibility, enables proactive issue detection, and supplies data for informed optimization decisions.

Question 3

What is the 80/20 rule as applied to performance optimization?

Accepted Answer

80% of performance gains come from optimizing 20% of the code or configuration

Answer

The 80/20 rule (Pareto principle) in optimization means focusing on the critical 20% of areas that will yield 80% of performance improvements, maximizing efficiency.

Question 4

When should performance testing be conducted?

Accepted Answer

Throughout the development lifecycle and before major releases

Answer

Performance testing throughout the lifecycle catches issues early when they are cheaper to fix and prevents performance regressions in new releases.

Question 5

What is capacity planning?

Accepted Answer

Predicting future resource needs based on growth trends and requirements

Answer

Capacity planning uses growth trends and requirements to predict future needs, ensuring adequate resources are available without over-provisioning.
