# Performance Audit Workflow
|
|
|
|
## Step 1: Establish Baseline
|
|
- Measure current performance:
|
|
- API: response time (p50, p95, p99), throughput
|
|
- Frontend: LCP, FID, CLS, bundle size
|
|
- Function: execution time, memory usage
|
|
- Record numbers BEFORE any changes
|
|
- Use project's existing tools or:
|
|
- Python: `time`, `cProfile`, `memory_profiler`
|
|
- JS/TS: `performance.now()`, Lighthouse, `webpack-bundle-analyzer`
|
|
- API: `curl -w @-` timing, `ab`, `wrk`
|
|
|
|
## Step 2: Profile
|
|
- Identify WHERE time is spent:
|
|
- Database queries (N+1, missing indexes, full scans)
|
|
- Network calls (sequential vs parallel, caching)
|
|
- CPU (algorithmic complexity, unnecessary computation)
|
|
- Memory (leaks, large allocations, unnecessary copies)
|
|
- I/O (file reads, disk writes)
|
|
|
|
## Step 3: Identify Top 3 Bottlenecks
|
|
- Rank by impact (% of total time)
|
|
- Focus on top 3 — don't optimize everything
|
|
- For each: document what, why slow, potential fix
|
|
|
|
## Step 4: Checkpoint
|
|
- `checkpoint: before perf-audit $target`
|
|
|
|
## Step 5: Fix (One at a Time)
|
|
- Fix #1 bottleneck → measure → confirm improvement
|
|
- Fix #2 bottleneck → measure → confirm improvement
|
|
- Fix #3 bottleneck → measure → confirm improvement
|
|
- After each fix: run tests — no regressions
|
|
|
|
## Step 6: Final Measurement
|
|
- Re-run baseline measurements
|
|
- Compare before/after
|
|
- Report: metric, before, after, improvement %
|
|
|
|
## Step 7: Commit
|
|
- `perf: optimize $target — <summary of improvements>`
