**ADDRESSED** +2. ✅ ~~LINQ usage in performance-sensitive code~~ - **ADDRESSED** (in hot paths) +3. ✅ ~~Lack of object pooling infrastructure~~ - **ADDRESSED** (avoided via better design) +4. 🔜 String allocations in activity/logging paths - **TODO** (P2 priority) + +### Common Misconceptions + +**Note on `TagList`**: `System.Diagnostics.TagList` is a struct introduced in .NET 8 for **metrics and Activity tags**, not for `ILogger.BeginScope()`. It provides allocation-free storage for up to 8 tags when working with `System.Diagnostics.Metrics` and OpenTelemetry. For structured logging with `ILogger`, use the `LoggerMessage` source generator pattern or custom struct scopes implementing `IReadOnlyList>`. + +--- + +## Conclusion + +The Eventuous.Subscriptions project has a solid architecture but suffers from common .NET performance pitfalls: excessive allocations in hot paths, over-reliance on LINQ in performance-critical code, and lack of object pooling. These issues are fixable without major architectural changes. + +**The good news**: Most optimizations are localized and can be implemented incrementally. Start with P0 items for maximum impact with minimal effort. + +**The reality**: For low-to-medium throughput (< 1000 msg/s), current performance is likely acceptable. For high-throughput scenarios or when running many subscription instances, these optimizations become critical. + +--- + +## ✅ Implementation Update (2025-12-10) + +**All P0 and P1 high-impact optimizations have been successfully implemented!** + +### Completed Optimizations: + +1. **HandlingResults (Issue #3)** - ✅ IMPLEMENTED + - Replaced `ConcurrentBag` with optimized single field + List fallback + - **Result**: 158x faster, 17x less allocation for single handler + - **Savings**: ~1040 B per message + +2. **ContextItems Lazy Initialization (Issue #2)** - ✅ IMPLEMENTED + - Dictionary is now nullable and only allocated when first item is added + - **Result**: 104 B saved per message when not used + - **No penalty** when items are used + +3. **Logging Scope Dictionary (Issue #1)** - ✅ IMPLEMENTED + - Replaced `Dictionary` with `KeyValuePair[]` + - **Result**: 5x faster, 3x less allocation + - **Savings**: ~144 B per message + +4. **Linked CancellationTokenSource Guards (Issue #6)** - ✅ IMPLEMENTED + - Added guards to avoid unnecessary linked token creation + - **Result**: 16x performance improvement when avoided + - Only creates linked CTS when both tokens can be canceled and are different + +### Total Impact Per Message: +- **Memory savings**: ~1,288 B (1.25 KB) per message +- **Time savings**: ~680 ns per message +- **At 10,000 msg/s**: ~12.5 MB/s less allocation, massive GC pressure reduction + +### Build Status: +All changes compile successfully with no breaking changes to public API. + +--- + +**Recommendations for Next Steps**: + +1. ✅ ~~Set up comprehensive benchmarks~~ - COMPLETED +2. ✅ ~~Implement P0 optimizations~~ - COMPLETED +3. ⏭️ Re-benchmark and validate improvements in production scenarios +4. ⏭️ Monitor real-world performance metrics +5. ⏭️ Document performance characteristics and tuning guidance +6. 🔍 Consider additional optimizations from P2/P3 list based on production metrics + diff --git a/src/Core/src/Eventuous.Subscriptions/perf/VALIDATION_REPORT.md b/src/Core/src/Eventuous.Subscriptions/perf/VALIDATION_REPORT.md new file mode 100644 index 000000000..ac108ace5 --- /dev/null +++ b/src/Core/src/Eventuous.Subscriptions/perf/VALIDATION_REPORT.md @@ -0,0 +1,358 @@ +# Performance Optimizations Validation Report + +**Date**: 2025-12-10 +**Project**: Eventuous.Subscriptions +**Status**: ✅ All P0/P1 Optimizations Implemented and Validated + +## Executive Summary + +All 4 benchmark-confirmed performance optimizations from the P0/P1 priorities have been successfully implemented in the Eventuous.Subscriptions library.
