go-stress-testing is a load testing tool written in Go that simulates concurrent users with goroutines to maximize CPU resource utilization.
The tool addresses the need to benchmark system performance under load by generating HTTP and gRPC traffic. It models each simulated user as a single goroutine, allowing a single machine to generate high volumes of concurrent connections. The approach supports HTTP/1.1 and HTTP/2.0 long connections, with straightforward extension possible for private protocols. The README documents how to conduct load testing across different scenarios, from short HTTP connections targeting over 10,000 QPS to long-lived connections reaching 1 million concurrent connections on a single machine.
The tool suits developers and operators who need to validate server capacity before production deployment. It works well for testing Go web services and gRPC endpoints, and the README includes practical guidance on kernel tuning and client configuration needed to achieve high connection counts. The project positions itself alongside established tools like Apache Bench, Locust, and JMeter, offering a lightweight alternative implemented in Go that avoids the overhead of heavier frameworks. The README provides a comparison table of these tools to help users select based on their specific needs.
The project maintains active engagement with practical examples and documentation. The repository includes two complete stress-testing implementation projects demonstrating real-world scenarios. The tool generates HTML test reports with AI-based scoring of results. The codebase includes detailed explanations of load-testing concepts, terminology, and metrics interpretation, suggesting sustained effort to make the tool accessible to users unfamiliar with performance testing methodology.
