The tool provides detailed performance metrics and supports custom protobuf messages for realistic testing scenarios.
|
Key Features:
- High-performance concurrent load testing with configurable concurrency levels
- Supports custom protobuf message definitions and complex call scenarios
- Provides detailed latency metrics including percentiles and throughput statistics
- Simple CLI interface with JSON/TOML configuration support
|
Use Cases:
- Benchmarking gRPC API endpoints under load before production deployment
- Identifying performance bottlenecks and latency issues in microservices
- Capacity planning and determining maximum throughput of gRPC services
|
Alternatives:
-
ghz-web
– Web UI companion for ghz that provides visual reporting and monitoring
-
grpc_bench
– Alternative benchmarking tool with different configuration approach
