# Benchmark Comparison Report: v4.3.0 vs Turbo-Enabled ## Summary This report compares the performance of DTail v4.3.0 (baseline) with the current version that has turbo boost mode enabled by default. ## Performance Improvements ### DCat Operations - **10MB file**: - v4.3.0: 9.363 MB/sec - Turbo: 246.8 MB/sec - **Improvement: 2,535% (26.3x faster)** ### DGrep Operations (10MB file) - **1% hit rate**: - v4.3.0: 25.38 MB/sec - Turbo: 363.9 MB/sec - **Improvement: 1,334% (14.3x faster)** - **10% hit rate**: - v4.3.0: 22.81 MB/sec - Turbo: 342.6 MB/sec - **Improvement: 1,402% (15.0x faster)** - **50% hit rate**: - v4.3.0: 16.14 MB/sec - Turbo: 265.1 MB/sec - **Improvement: 1,543% (16.4x faster)** - **90% hit rate**: - v4.3.0: 10.99 MB/sec - Turbo: 210.0 MB/sec - **Improvement: 1,811% (19.1x faster)** ### DMap Operations (10MB file) - **Count query**: - v4.3.0: 17.09 MB/sec - Turbo: 21.77 MB/sec - **Improvement: 27.4%** - **Sum/Avg query**: - v4.3.0: 13.54 MB/sec - Turbo: 21.05 MB/sec - **Improvement: 55.5%** - **Min/Max query**: - v4.3.0: 17.46 MB/sec - Turbo: 21.80 MB/sec - **Improvement: 24.9%** - **Multi-field query**: - v4.3.0: 21.85 MB/sec - Turbo: 21.32 MB/sec - **Slight decrease: -2.4%** (within margin of error) ## Key Findings 1. **Massive improvements in DCat and DGrep**: The turbo boost mode shows extraordinary performance gains for file reading (DCat) and searching (DGrep) operations, with improvements ranging from 14x to 26x faster. 2. **Moderate improvements in DMap**: MapReduce operations show more modest but still significant improvements of 25-55% for most query types. 3. **Consistent performance across hit rates**: DGrep performance improvements scale well across different hit rates, with even better improvements at higher hit rates. ## Technical Details The turbo boost mode achieves these improvements through: - Direct writing bypassing channels for cat/grep/tail operations - Direct line processing without channels for MapReduce in server mode - Batch processing to reduce lock contention - Memory pooling to reduce garbage collection pressure ## Recommendation The turbo boost mode delivers exceptional performance improvements and should remain enabled by default. The performance gains are substantial enough to justify any potential trade-offs in code complexity.
