go-client-server-benchmarks

This project compares the performance of several client-server communication libraries and frameworks for Go.

Tested libraries/frameworks

• google.golang.org/grpc
• github.com/cloudwego/kitex
• github.com/cmd-stream/cmd-stream-go

Short Benchmarks Description

In this benchmarks 1,2,4,8,16 clients send echo requests to the server as follows:

• Each client executes all echo requests simultaneously in separate goroutines.
• The same data is used for all participants, it is generated once and then used by everyone.
• Size of the data varies from 17 to 1024 bytes.
• The size of the read and write buffers is limited to 4096 bytes.
• The delay of each response on the server is 30 ms.
• The received data is checked - it must match the sent data.

Results

All results were obtained on a single laptop (with the connected charger and fan running at full speed):

• CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics
• OS: Gentoo 5.19.9-gentoo x86_64 GNU/Linux
• Go: 1.24.1

with the following commands:

GEN_SIZE=400000 go test -bench BenchmarkQPS -count=10 -timeout=30m
go test -bench BenchmarkFixed -benchtime=100000x -benchmem -count=10

To get more comparable results, let's check how well all participants can handle 100,000 simultaneous requests:
