The article provides an example implementation of an echo server using the TCP protocol with the Gain framework and also discusses the OnStart, OnAccept, OnRead, OnWrite, and OnClose methods of the EventHandler interface in Gain.
The author demonstrates how to start a Gain server and provides a simple client-side logic for testing the server.
- Gain can be faster than the fastest epoll-based frameworks written in Go since it is built on top of the io_uring API and was designed from the very beginning to be as fast as possible.
- io_uring uses a pair of ring buffers, one for submitting requests and another for reporting results.
- It uses a different programming model compared to the net package in Go to minimize the number of system calls and improve performance.
