Oha
oha 是一个命令行 HTTP 负载测试和基准测试工具。它作为一个延迟分析工具和性能监视器，向 Web 服务器发送大量请求以测量稳定性并识别性能瓶颈。
该工具具有一个终端用户界面，可在活动测试期间显示实时延迟统计信息和请求动画。它包括一个用于校正协调遗漏（coordinated omission）的机制，确保响应时间百分位数和延迟分布报告准确。
其功能涵盖 HTTP 负载生成、通过随机目标 URL 进行流量模拟以及请求速率控制。该项目通过 TLS 和双向 TLS 支持安全通信，并提供以 JSON、CSV 和 SQLite 格式导出性能指标的选项。
该工具可以在容器化环境中执行，以保持不同主机系统之间的一致性。
Features
- HTTP Load Testing - Provides high-volume HTTP request generation to measure the performance, stability, and bottlenecks of web services.
- Request Rate Controllers - Regulates traffic flow using fixed queries-per-second, burst modes, or unlimited rates.
- HTTP Request Dispatchers - Implements concurrent HTTP request dispatching to saturate target servers and measure performance under heavy load.
- Latency Histograms - Generates detailed response time histograms and performance data to calculate accurate latency percentiles.
- Request Rate Limiting - Regulates outgoing request flow using a timing mechanism to maintain a specific queries-per-second target.
- Latency Monitoring - Provides real-time measurement and tracking of request response times to identify performance bottlenecks.
- Coordinated Omission Correction - Implements a mechanism to correct for coordinated omission, ensuring accurate latency distributions and report statistics.
- Coordinated Omission Corrections - Implements a correction mechanism for coordinated omission to ensure accurate latency distribution and percentile reporting.
- HTTP Endpoint Benchmarking - Measures the performance and response speed of HTTP endpoints using high-volume request loads.
- Web Application Benchmarking - Calculates response time statistics and latency percentiles to identify performance bottlenecks in web applications.
