如果你计划构建可靠， 内存安全[1] ，高性能的应用程序，那么 Rust＆Go 无疑会是你的选择。
如果您希望从内部应用程序中获得更高的性能，则可能还需要考虑使用 gRPC[2] 而不是普通的 REST[3] API。所有这些都是减少您的计算开销的解决方案。
我尝试比较各种库以了解它们的性能，并希望对你有所帮助。
- tower-grpc[4] (Rust)高性能 rust 库，尽管已被 tonic 替代
- grpc-go[5] (Golang)grpc 的官方 Go 模块
- grpc-rust[6] (Rust)仍在开发中，另一个 rust grpc 库。看起来很不错
- tonic[7] (Rust)tower-grpc 库的改进更新，支持新的 await 语法
- grpc-node[8] (NodeJs)包含有基准基准点
- grpc-rs[9] (Rust — C bindings)使用 grpc[10] 的 rust 库
对于基准测试，我将在 gRPC 中使用与 Hey[11] 等效的 ghz[12] 。
该测试将重点关注如果使用上述每个库将 10,000 个并发请求的相同负载发送到服务器，将有多少开销。我将为每个使用相同的 helloworld[13] greeter。不会为任何测试启用 TLS，因此我们可以大致了解每种测试的原始性能。

吞吐量（请求/秒）。越高越好。
结果表明，在性能方面，rust 与 node 相当，这是一个令人震惊的结果。
Go 库在并发性和最小开销方面均表现出色。
