Bombardier
Bombardier is a concurrent HTTP load generator and performance benchmarking tool written in Go. It functions as a latency distribution analyzer and benchmarking utility designed to measure the throughput and response speed of HTTP services by simulating high-volume request loads.
The tool provides specific capabilities for TLS benchmarking, supporting client certificate authentication and the ability to bypass server certificate verification. It distinguishes itself through the use of a token-bucket algorithm for precise request rate limiting and the use of templates to export benchmark results into JSON or human-readable formats.
The project covers a broad range of performance analysis areas, including concurrent connection simulation, network throughput measurement, and HTTP error tracking. It analyzes API latency through percentile-based response time tracking and allows for the configuration of load profiles via custom headers and request payloads.
The application is distributed as a cross-platform executable binary.
