gnet is an event-driven networking framework that is fast and lightweight. It makes direct epoll and kqueue syscalls rather than using the standard Go net package and works in a similar manner as netty and libuv, which makes
gnet achieve a much higher performance than Go net.
gnet is not designed to displace the standard Go net package, but to create a networking client/server framework for Go that performs on par with Redis and Haproxy for networking packets handling (although it does not limit itself to these areas), therefore,
gnet is not as comprehensive as Go net, it only provides the core functionalities (by a concise API set) of a networking application and it is not planned on being a full-featured networking framework, as I think net has done a good enough job in this area.
gnet sells itself as a high-performance, lightweight, non-blocking, event-driven networking framework written in pure Go which works on transport layer with TCP/UDP protocols and Unix Domain Socket , so it allows developers to implement their own protocols(HTTP, RPC, WebSocket, Redis, etc.) of application layer upon
gnet for building diversified network applications, for instance, you get an HTTP Server or Web Framework if you implement HTTP protocol upon
gnet while you have a Redis Server done with the implementation of Redis protocol upon
gnet and so on.
gnet derives from the project:
evio while having a much higher performance and more features.
Unix Domain Socket
epollon Linux and
gnet is available as a Go module and we highly recommend that you use
gnet via Go Modules, with Go 1.11 Modules enabled (Go 1.11+), you can just simply add
import "github.com/panjf2000/gnet" to the codebase and run
go mod download/go mod tidy or
go [build|run|test] to download the necessary dependencies automatically.
go get -u github.com/panjf2000/gnet/v2
go get -u github.com/panjf2000/gnet
The following companies/organizations use
gnet as the underlying network service in production.
