BootWeaver

openKylin 启动性能分析与优化工具。

概述

通过 systemd 数据采集、依赖分析、深度统计算法，识别启动瓶颈，自动化服务裁剪和配置调优。

实际测试（openKylin 2.0 SP2, VMware Workstation）：

• 优化前: 11.92s
• 优化后: 7.83s（降幅 34.3%）
• 用户空间: 8.68s → 4.56s（降幅 47.5%）

使用方法

./run.sh analyze       # 采集启动数据并分析
sudo ./run.sh optimize # 应用优化配置
./run.sh diagnose      # 规则引擎诊断瓶颈
make test              # 运行单元测试

BootWeaver

Boot performance analysis and optimization tool for openKylin.

Overview

Collects systemd boot data, analyzes service dependencies, identifies bottlenecks, and automates optimization.

Tested on openKylin 2.0 SP2 (VMware Workstation):

• Before: 11.92s
• After: 7.83s (34.3% improvement)
• Userspace: 8.68s → 4.56s (47.5% improvement)

Quick Start

./run.sh analyze       # Collect boot data and analyze
sudo ./run.sh optimize # Apply optimization
./run.sh diagnose      # Rule-based bottleneck diagnosis
make test              # Run unit tests

Requirements

• Python >= 3.8
• systemd with systemd-analyze
• Linux: openKylin / Ubuntu / Debian
