Eliminating Global Lock Bottlenecks
Under traffic surges, naive rate limiters with a single global mutex serialize goroutines across CPU cores, creating cascading timeouts. Remote Redis round-trips add 15–30ms network overhead per request.
Production Deliverables:
- ✓64-way Sharded Mutex Architecture: Striped locks by hashed user key to distribute core utilization.
- ✓Tiered Sliding Window + Redis: Microsecond local in-memory token bucket synchronized asynchronously.
- ✓Automated Load Benchmarks: Stress-testing suites verifying throughput past 100k+ req/sec.
