Performance Optimization Workflow
Principle: Always measure before optimizing — never optimize based on guesses.
Measurement
1. Profiling (primary)
cargo build --profile profiling
samply record ./target/profiling/trev [args]
Analyze profiler output and identify bottlenecks before making changes.
2. Benchmarking (hot path comparison)
just bench
- Criterion benchmarks (
benches/ directory)
- Compare results before and after changes
Workflow
- Measure: Establish baseline with profiler or benchmarks
- Analyze: Identify bottlenecks
- Optimize: Improve only the identified areas
- Verify: Re-measure to confirm improvement
