Multi-Region Load Testing and Performance Validation

[perigrin]

User Story

Implement multi-region load testing using TDD to validate IRC network performance
under realistic usage patterns. Write tests that simulate concurrent users across
both regions, cross-region communication, and services load to ensure the network
meets performance and reliability requirements.

Requirements:
- Create comprehensive load testing framework for multi-region setup
- Test concurrent users and cross-region message propagation
- Validate services performance with distributed servers
- Measure and validate network performance under load

Expected Output

• tests/test_multi_region_load.pl - Multi-region load testing framework (Perl)
• scripts/cross-region-simulator.pl - Cross-region user simulation (Perl)
• scripts/network-performance-monitor.pl - Network latency monitoring (Perl)
• config/production-load-scenarios.yaml - Production load test configuration
• docs/production-readiness-report.md - Final deployment validation report
• Validated multi-region IRC network ready for production deployment

Acceptance Criteria

• Write failing tests for multi-region load and performance
• Implement load testing framework supporting both US and EU regions
• Tests simulate 200+ concurrent users across both servers
• Cross-region message propagation tested under load
• Services performance validated with distributed server load
• Network latency and throughput measured and documented
• Resource utilization tracked across all components
• Performance degradation thresholds identified
• Capacity limits established and documented
• Recovery from overload conditions tested
• All multi-region performance tests pass

Context

Multi-region load testing validates that the distributed IRC network can handle realistic usage patterns while maintaining performance and reliability. This testing ensures the network is ready for production deployment and establishes operational capacity limits.
