This project compares the performance of several client-server communication libraries/frameworks for Golang.
In this benchmarks 1,2,4,8,16 clients send echo requests to the server as follows:
- Each client uses only one connection and 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.
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: 1.22.7
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:
