Vault benchmark is an open source tool designed to test the performance of HashiCorp Vault auth methods and secrets engines through load testing, giving organizations confidence in their secrets management lifecycle. The tool uses the HTTP load testing utility Vegeta and can be run against non-production Vault clusters isolated from production systems. By using Vault benchmark, engineering teams can discover aspects of their architecture that are performing well or need improvement, as well as opportunities for optimization. The benefits include understanding how different configurations impact cluster performance and identifying potential issues before they affect the end-user experience. To use Vault benchmark, users must set up infrastructure dependencies and run the binary with a configuration file, which should be used to configure resources required for testing. The tool is intended to be used in non-production environments and can help organizations improve their overall performance by following production hardening guidelines and reference architecture.
