+# SharpCompress Performance Benchmarks
+
+This project contains performance benchmarks for SharpCompress using [BenchmarkDotNet](https://benchmarkdotnet.org/).
+
+## Overview
+
+The benchmarks test all major archive formats supported by SharpCompress:
+- **Zip**: Read (Archive & Reader API) and Write operations
+- **Tar**: Read (Archive & Reader API) and Write operations, including Tar.GZip
+- **Rar**: Read operations (Archive & Reader API)
+- **7Zip**: Read operations for LZMA and LZMA2 compression
+- **GZip**: Compression and decompression
+
+## Running Benchmarks
+
+### Run all benchmarks
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release
+```
+
+### Run specific benchmark class
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --filter "*ZipBenchmarks*"
+```
+
+### Run with specific job configuration
+```bash
+# Quick run for testing (1 warmup, 1 iteration)
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --job Dry
+
+# Short run (3 warmup, 3 iterations)
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --job Short
+
+# Medium run (default)
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --job Medium
+```
+
+### Export results
+```bash
+# Export to JSON
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --exporters json
+
+# Export to multiple formats
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --exporters json markdown html
+```
+
+### List available benchmarks
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --list flat
+```
+
+## Baseline Results
+
+The baseline results are stored in `baseline-results.md` and represent the expected performance characteristics of the library. These results are used in CI to detect significant performance regressions.
+
+To update the baseline:
+1. Run the benchmarks: `dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --exporters markdown --artifacts baseline-output`
+2. Combine the results: `cat baseline-output/results/*-report-github.md > baseline-results.md`
+3. Review the changes and commit if appropriate
+
+## CI Integration
+
+The performance benchmarks run automatically in GitHub Actions on:
+- Push to `master` or `release` branches
+- Pull requests to `master` or `release` branches
+- Manual workflow dispatch
+
+Results are displayed in the GitHub Actions summary and uploaded as artifacts.
+
+## Benchmark Configuration
+
+The benchmarks are configured with minimal iterations for CI efficiency:
+- **Warmup Count**: 1 iteration
+- **Iteration Count**: 3 iterations
+- **Invocation Count**: 1
+- **Unroll Factor**: 1
+- **Toolchain**: InProcessEmitToolchain (for fast execution)
+
+These settings provide a good balance between speed and accuracy for CI purposes. For more accurate results, use the `Short`, `Medium`, or `Long` job configurations.
+
+## Memory Diagnostics
+
+All benchmarks include memory diagnostics using `[MemoryDiagnoser]`, which provides:
+- Total allocated memory per operation
+- Gen 0/1/2 collection counts
+
+## Understanding Results
+
+Key metrics in the benchmark results:
+- **Mean**: Average execution time
+- **Error**: Half of 99.9% confidence interval
+- **StdDev**: Standard deviation
+- **Allocated**: Total managed memory allocated per operation
+
+## Contributing
+
+When adding new benchmarks:
+1. Create a new class in the `Benchmarks/` directory
+2. Inherit from `ArchiveBenchmarkBase` for archive-related benchmarks
+3. Add `[MemoryDiagnoser]` attribute to the class
+4. Use `[Benchmark(Description = "...")]` for each benchmark method
+5. Add `[GlobalSetup]` for one-time initialization
+6. Update this README if needed

+# Performance Benchmarks Implementation Summary
+
+## Overview
+This implementation adds comprehensive performance benchmarks using BenchmarkDotNet to the SharpCompress project. The benchmarks run automatically in CI and provide baseline comparisons to detect performance regressions.
+
+## What Was Implemented
+
+### 1. BenchmarkDotNet Integration
+- Added BenchmarkDotNet v0.14.0 package to `Directory.Packages.props`
+- Configured the Performance project to use BenchmarkDotNet with minimal iterations for CI efficiency
+- Set up InProcessEmitToolchain for fast execution with:
+ - 1 warmup iteration
+ - 3 measurement iterations
+ - Memory diagnostics enabled
+
+### 2. Comprehensive Benchmark Suite
+Created benchmarks for all major formats in `tests/SharpCompress.Performance/Benchmarks/`:
+
+#### ZipBenchmarks
+- Extract all entries using Archive API
+- Extract all entries using Reader API
+- Create archive with small files
+
+#### TarBenchmarks
+- Extract all entries using Archive API
+- Extract all entries using Reader API
+- Extract Tar.GZip archives
+- Create archive with small files
+
+#### RarBenchmarks
+- Extract all entries using Archive API
+- Extract all entries using Reader API
+
+#### SevenZipBenchmarks
+- Extract LZMA compressed archives
+- Extract LZMA2 compressed archives
+
+#### GZipBenchmarks
+- Compress 100KB of data
+- Decompress 100KB of data
+
+### 3. GitHub Actions CI Integration
+Created `.github/workflows/performance-benchmarks.yml` that:
+- Runs on push to master/release branches
+- Runs on pull requests to master/release branches
+- Supports manual workflow dispatch
+- Displays benchmark results in GitHub Actions summary
+- Compares results with baseline
+- Uploads results as artifacts
+
+### 4. Baseline Results
+Established baseline performance results in `tests/SharpCompress.Performance/baseline-results.md` showing expected performance characteristics for:
+- CPU time (Mean, Error, StdDev, Median)
+- Memory allocations
+- All supported archive formats
+
+### 5. Documentation
+Created comprehensive documentation:
+- `tests/SharpCompress.Performance/README.md` - Complete guide for running benchmarks
+- This summary document
+- Inline code comments
+
+### 6. Code Quality
+- Applied CSharpier formatting to all benchmark code
+- Added BenchmarkDotNet.Artifacts/ to .gitignore to prevent artifact pollution
+- Followed existing project conventions
+
+## How to Use
+
+### Run All Benchmarks
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release
+```
+
+### Run Specific Benchmarks
+```bash
+# Run only Zip benchmarks
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --filter "*ZipBenchmarks*"
+
+# Run with different job configuration
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --job Short
+```
+
+### View Results in CI
+1. Navigate to GitHub Actions
+2. Select the "Performance Benchmarks" workflow
+3. View the run summary for formatted benchmark results
+4. Download artifacts for detailed JSON/HTML reports
+
+## Key Design Decisions
+
+### Minimal Iterations for CI
+- Configured with minimal iterations (1 warmup, 3 measurements) to keep CI runs fast
+- Provides sufficient data for detecting major performance changes
+- Users can run with longer configurations locally for more precision
+
+### InProcessEmitToolchain
+- Uses InProcessEmitToolchain for fast execution
+- Avoids process spawning overhead
+- Suitable for CI where speed matters more than absolute isolation
+
+### Test Archive Usage
+- Benchmarks use existing test archives from `tests/TestArchives/Archives/`
+- Ensures consistency with actual test data
+- Tests realistic scenarios
+
+### Memory Diagnostics
+- All benchmarks include `[MemoryDiagnoser]` attribute
+- Tracks memory allocations and GC pressure
+- Helps detect memory-related regressions
+
+## Baseline Comparison Strategy
+The baseline file serves as a reference for expected performance. When reviewing benchmark results:
+1. Compare Mean times against baseline
+2. Look for significant increases (>20% slower)
+3. Check memory allocations for unexpected growth
+4. Consider that some variance is normal due to different CI hardware
+
+## Maintenance
+To update baselines after intentional performance changes:
+1. Run benchmarks: `dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --exporters markdown --artifacts baseline-output`
+2. Combine results: `cat baseline-output/results/*-report-github.md > tests/SharpCompress.Performance/baseline-results.md`
+3. Review changes
+4. Commit if appropriate
+
+## Future Enhancements
+Potential improvements for future iterations:
+- Add more granular benchmarks (e.g., single file extraction)
+- Benchmark async operations
+- Add benchmarks for different compression levels
+- Implement automated regression detection with thresholds
+- Add comparative benchmarks against System.IO.Compression
+- Include larger archive scenarios
+
+## Testing
+All benchmarks have been tested and verified to:
+- Compile successfully
+- Run without errors
+- Produce consistent results
+- Work with the CI workflow
+- Follow project code style

The baseline results are stored in `baseline-results.md` and represent the expected performance characteristics of the library. These results are used in CI to detect significant performance regressions.
-To update the baseline:
+### Generate Baseline (Automated)
+
+Use the build target to generate baseline results:
+```bash
+dotnet run --project build/build.csproj -- generate-baseline
+```
+
+This will:
+1. Build the performance project
+2. Run all benchmarks
+3. Combine the markdown reports into `baseline-results.md`
+4. Clean up temporary artifacts
+
+### Generate Baseline (Manual)
+
+To manually update the baseline:
1. Run the benchmarks: `dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --exporters markdown --artifacts baseline-output`
2. Combine the results: `cat baseline-output/results/*-report-github.md > baseline-results.md`
3. Review the changes and commit if appropriate
+## JetBrains Profiler Integration
+
+The performance project supports JetBrains profiler for detailed CPU and memory profiling during local development.
+
+### Prerequisites
+
+Install JetBrains profiler tools from: https://www.jetbrains.com/profiler/
+
+### Run with CPU Profiling
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --profile --type cpu --output ./my-cpu-snapshots
+```
+
+### Run with Memory Profiling
+```bash
+dotnet run --project tests/SharpCompress.Performance/SharpCompress.Performance.csproj --configuration Release -- --profile --type memory --output ./my-memory-snapshots
+```
+
+### Profiler Options
+- `--profile`: Enable profiler mode
+- `--type cpu|memory`: Choose profiling type (default: cpu)
+- `--output `: Specify snapshot output directory (default: ./profiler-snapshots)
+
+The profiler will run a sample benchmark and save snapshots that can be opened in JetBrains profiler tools for detailed analysis.
+
## CI Integration
The performance benchmarks run automatically in GitHub Actions on:
