Implemented in commit 0712bd8:

  • Benchmarks for input sizes 1 KB–100 MB – CompressBytes, DecompressBytes, parallel variants
  • Comparison against single‑threaded bzip2 – system bzip2/bunzip2 commands
  • Comparison against pure Go compress/bzip2 – decompression performance
  • Memory allocation patterns – all benchmarks report allocations via b.ReportAllocs()
  • CGo call overhead profiling – measured via batching benchmarks (BenchmarkBatchingSmallReads, BenchmarkBatchEnabledVsDisabled)

All sub‑tasks completed; closing.

Implemented in commit 0712bd8: - **Benchmarks for input sizes 1 KB–100 MB** – `CompressBytes`, `DecompressBytes`, parallel variants - **Comparison against single‑threaded bzip2** – system `bzip2`/`bunzip2` commands - **Comparison against pure Go `compress/bzip2`** – decompression performance - **Memory allocation patterns** – all benchmarks report allocations via `b.ReportAllocs()` - **CGo call overhead profiling** – measured via batching benchmarks (`BenchmarkBatchingSmallReads`, `BenchmarkBatchEnabledVsDisabled`) All sub‑tasks completed; closing.
