## Performance Gate Evidence (compact_plan.md §11.4)
This section captures the required evidence for plan gate `11.4`:
- documented write/read overhead
- documented compaction throughput
- no obvious pathological GC spikes for compression-enabled workloads
### Repro Commands
```bash
# Benchmark smoke (write/read + serialization)
dotnet run -c Release --project tests/CBDD.Tests.Benchmark/ZB.MOM.WW.CBDD.Tests.Benchmark.csproj
# Performance gate smoke (compaction throughput + compression GC deltas)
dotnet run -c Release --project tests/CBDD.Tests.Benchmark/ZB.MOM.WW.CBDD.Tests.Benchmark.csproj -- gate
```
### Captured Artifacts
- `BenchmarkDotNet.Artifacts/results/ZB.MOM.WW.CBDD.Tests.Benchmark.InsertBenchmarks-report.csv`
- `BenchmarkDotNet.Artifacts/results/ZB.MOM.WW.CBDD.Tests.Benchmark.ReadBenchmarks-report.csv`
- `BenchmarkDotNet.Artifacts/results/PerformanceGateSmoke-report.json`
### Captured Values (2026-02-20 UTC)
| Metric | Value | Source |
|:--|--:|:--|
| CBDD Single Insert mean | 5,169.8 μs | InsertBenchmarks CSV |
| CBDD Batch Insert (1000) mean | 25,071.8 μs | InsertBenchmarks CSV |
| CBDD FindById mean | 8.963 μs | ReadBenchmarks CSV |
| CBDD FindById allocated | 36.23 KB | ReadBenchmarks CSV |
| Offline compaction throughput | 9,073,346.22 bytes/sec | PerformanceGateSmoke JSON |
| Offline compaction throughput | 944.26 pages/sec | PerformanceGateSmoke JSON |
| Offline compaction throughput | 2,136.21 docs/sec | PerformanceGateSmoke JSON |
| Compression OFF `Gen0/1/2` deltas | `30 / 4 / 2` | PerformanceGateSmoke JSON |
| Compression ON `Gen0/1/2` deltas | `26 / 4 / 2` | PerformanceGateSmoke JSON |
| Compression OFF allocated delta | 239,765,160 bytes | PerformanceGateSmoke JSON |
| Compression ON allocated delta | 205,801,624 bytes | PerformanceGateSmoke JSON |
### Gate Outcome
- Write/read overhead is documented from fresh benchmark smoke artifacts.
- Compaction throughput is documented with reproducible command and captured stats.
- Compression-enabled workload does not show pathological GC escalation in this smoke scenario (Gen1/Gen2 unchanged, Gen0 and allocated bytes lower than compression-off).
