# AyCode.Benchmark

BenchmarkDotNet-based performance benchmarking console app. Compares AcBinary serializer against MessagePack, BSON, and JSON across various scenarios.

## Key Files

- **`Program.cs`** — CLI entry point with `--quick`, `--test`, `--minimal`, `--simple`, `--complex`, `--msgpack`, `--sizes`, `--jitasm` modes. Collects results to `Test_Benchmark_Results/` at solution root.
- **`SerializationBenchmarks.cs`** — Primary suite: MinimalBenchmark, SimpleBinaryBenchmark, ComplexBinaryBenchmark, MessagePackComparisonBenchmark, AcBinaryVsMessagePackFullBenchmark, SizeComparisonBenchmark, LargeScaleBenchmark (~25K objects), AcJsonVsSystemTextJsonBenchmark.
- **`SourceGeneratorBenchmarks.cs`** — Source-generated vs runtime reflection serializers. Includes PureContractlessBenchmark, SourceGeneratorVsRuntimeBenchmark, RepeatedStringBenchmark (string interning).
- **`SignalRCommunicationBenchmarks.cs`** — Full-stack SignalR message performance: client creation → MessagePack serialization → server deserialization → response → round-trip.
- **`SignalRRoundTripBenchmarks.cs`** — Real SignalR infrastructure benchmarks: primitives, complex objects, collections, mixed parameters.
- **`JitDisassemblyBenchmark.cs`** — JIT analysis: generates .asm files to verify inlining decisions on serialize/deserialize hot paths.
- **`TaskHelperBenchmarks.cs`** — Task/timing utilities: WaitToAsync, ThreadPool (custom vs Task.Run), timing methods (UtcNow.Ticks vs TickCount64).
- **`RefForeachBenchmark.cs`** — Collection iteration patterns: array vs list, foreach vs index, ref readonly vs by-value for large structs.
- **`ValueTypePassingBenchmark.cs`** — Copy-by-value vs `in` parameter for 16-byte types (Decimal, DateTimeOffset, Guid).
