No performance benchmarks or load testing in CI

[yairfalse]

Problem

While control/examples/loadtest_runner.rs exists, there's no:

• Automated performance benchmarking
• Baseline latency/throughput numbers
• Performance regression detection in CI

Impact

• Performance regressions can ship unnoticed
• No data to compare against other proxies (Envoy, nginx)
• Hard to validate optimization work

Suggested Fix

1. Add criterion benchmarks for hot paths:

   • Maglev lookup
   • Router path matching
   • Header filtering

2. Add load test to CI (optional, on release branches):

   • Use wrk or hey against deployed RAUTA
   • Capture p50/p95/p99 latencies
   • Fail if regression > 10%

3. Document baseline numbers in README:

   • Requests/sec at various concurrency levels
   • Memory usage under load
   • Comparison with similar proxies

Files

• control/examples/loadtest_runner.rs (existing, needs integration)
• New: benches/ directory for criterion

More relevant now — the lock-free AtomicCircuitBreaker, AtomicTokenBucket, and ArcSwap health data should show measurable improvements over the previous RwLock-based implementation. wrk or criterion benchmarks against the proxy hot path would quantify the gains. The existing control/examples/loadtest_runner.rs could be the starting point.
