Profile and optimize application performance
Best for
Reducing latency and improving throughput when you have profiling data or suspect bottlenecks in critical code paths.
Inputs
- · Profiling report or slow code snippet
Outputs
- · Ranked optimization suggestions
- · Code examples (before/after)
- · Testing strategy to validate improvements
Requires
- · JProfiler, YourKit, or browser DevTools profilers
Preconditions
Performance data or hypothesis about slowness; baseline metrics helpful
Failure modes
- · Premature optimization without profiling → optimization may be ineffective
