gRPC Performance: tonic (Rust) vs grpc-go Benchmarked at Scale
A recent analysis compared the performance of gRPC implementations tonic (Rust) and grpc-go under real-world conditions. The findings revealed that Rust outperformed Go in terms of latency and memory efficiency, particularly for services constrained by CPU. This challenges the prevailing belief that Go is the superior choice for gRPC performance.
- ▪Production benchmarks showed that grpc-go consumed significantly more memory than expected under load.
- ▪Rust's tonic implementation provided better latency and memory consumption for CPU-constrained services.
- ▪The analysis highlighted that many teams optimize for incorrect performance metrics.
