What ghz is
ghz is a benchmarking and load testing tool for gRPC services. It runs as a command-line tool or as a Go package. Calls are defined by a .proto file or a compiled protoset, with request data and metadata supplied as JSON. Request rate and concurrency can each follow constant, step or linear schedules. Run settings can be kept in a JSON or TOML configuration file. Results print as a summary or export as CSV, JSON, HTML or InfluxDB formats. Binaries are available as downloads, through Homebrew, via go install or from a Docker build.
