From 17bf7e042496a4afcbf6ee7a583378adb3ec502d Mon Sep 17 00:00:00 2001 From: Paul Buetow Date: Wed, 22 Jul 2026 23:52:43 +0300 Subject: =?UTF-8?q?build:=20DTail=20fork=20=E2=80=94=20benchmarks,=20PGO?= =?UTF-8?q?=20tooling,=20Makefile,=20docker?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Squashed development of the build/benchmark/profiling tooling: - Turbo-vs-normal and per-tool benchmark harnesses under benchmarks/ (with dated baseline and result artifacts preserved), plus MapReduce/SSH/network suites. - Profile-Guided Optimization workflow (internal/tools/pgo lives with the code): Makefile targets (make pgo / pgo-quick / build-pgo), profile generation with non-zero-sample and representativeness guards. - Makefile targets for build, test (unit + integration), lint, vet, benchmarking and profiling; docker config updates. - .gitignore hardened against pgo profiles and accidental integration-test debug/output dumps.

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. \ No newline at end of file diff --git a/benchmarks/baselines/optimization_progression_summary.md b/benchmarks/baselines/optimization_progression_summary.md new file mode 100644 index 0000000..c8174f6 --- /dev/null +++ b/benchmarks/baselines/optimization_progression_summary.md @@ -0,0 +1,105 @@ +# DTail Performance Optimization Progression Summary + +Generated: 2025-07-04 + +This document summarizes the performance improvements achieved through successive optimizations: +1. **Pre-Turbo Mode** (v4.3.0 baseline) +2. **Turbo Mode** (enabled by default) +3. **Turbo Mode + PGO** (Profile-Guided Optimization) + +## Executive Summary + +The optimization journey shows dramatic performance improvements, with turbo mode providing the most significant gains (up to 21x for DCat, 15x for DGrep), while PGO added incremental improvements for specific workloads. + +## DCat Performance (File Reading) + +| File Size | Pre-Turbo | Turbo Mode | Turbo + PGO | Total Improvement | +|-----------|-----------|------------|-------------|-------------------| +| **10MB** | 17.77 MB/s | 242.8 MB/s | 259.9 MB/s | **14.6x faster** | +| **100MB** | 20.66 MB/s | 318.8 MB/s | 339.2 MB/s | **16.4x faster** | +| **1GB** | 15.66 MB/s | 320.3 MB/s | 330.4 MB/s | **21.1x faster** | + +### DCat Key Insights: +- Turbo mode delivers 13.7x to 20.4x speedup +- PGO adds additional 3.8% to 7.0% improvement +- Larger files benefit more from optimizations + +## DGrep Performance (Pattern Search) + +### 10MB Files +| Hit Rate | Pre-Turbo | Turbo Mode | Turbo + PGO | Total Improvement | +|----------|-----------|------------|-------------|-------------------| +| **1%** | 30.70 MB/s | 389.5 MB/s | 417.9 MB/s | **13.6x faster** | +| **10%** | 36.61 MB/s | 308.2 MB/s | 324.0 MB/s | **8.9x faster** | +| **50%** | 24.93 MB/s | 281.2 MB/s | 285.3 MB/s | **11.4x faster** | +| **90%** | 17.24 MB/s | 247.8 MB/s | 265.6 MB/s | **15.4x faster** | + +### 100MB Files (1% hit rate) +| Metric | Pre-Turbo | Turbo Mode* | Turbo + PGO | Total Improvement | +|--------|-----------|-------------|-------------|-------------------| +| MB/s | 37.71 | ~390 (est) | 493.5 | **13.1x faster** | +| Lines/sec | 663,620 | ~6,900,000 | 8,685,054 | **13.1x faster** | + +*Estimated based on 10MB performance scaling + +### DGrep Key Insights: +- Turbo mode delivers 8.4x to 14.4x speedup across different hit rates +- PGO adds 5-10% improvement for low hit rates +- Performance scales well with file size + +## DMap Performance (MapReduce Queries) + +### 10MB Files +| Query Type | Pre-Turbo | Turbo Mode* | Turbo + PGO | Total Improvement | +|------------|-----------|-------------|-------------|-------------------| +| **count** | 14.12 MB/s | ~21.7 MB/s | 15.45 MB/s | **9.4% faster** | +| **sum_avg** | 13.30 MB/s | ~21.0 MB/s | 17.05 MB/s | **28.2% faster** | +| **min_max** | 17.77 MB/s | ~21.8 MB/s | 21.08 MB/s | **18.6% faster** | +| **multi** | 16.57 MB/s | ~21.3 MB/s | 21.34 MB/s | **28.8% faster** | + +*Estimated from benchmark comparison data + +### 1GB Files (notable results) +| Query Type | Turbo Mode | Turbo + PGO | PGO Impact | +|------------|------------|-------------|------------| +| **min_max** | 28.67 MB/s | 47.21 MB/s | **+64.7%** | +| **multi** | 43.08 MB/s | 44.06 MB/s | **+2.3%** | + +### DMap Key Insights: +- Modest overall improvements compared to DCat/DGrep +- Turbo mode impact limited due to CPU-bound nature of MapReduce +- PGO shows mixed results, excellent for min_max on large files +- Total improvements range from 9% to 29% + +## Optimization Impact Summary + +### By Operation Type: +1. **I/O-Bound Operations (DCat)**: Massive 14-21x improvement +2. **Mixed I/O/CPU Operations (DGrep)**: Substantial 9-15x improvement +3. **CPU-Bound Operations (DMap)**: Modest 9-29% improvement + +### By Optimization Stage: +1. **Turbo Mode**: Game-changing impact + -
