Go&#s http.ServeMux Is All You Need

Optimization and application analysis of http.ServeMux in Go 1.22 standard library In the field of Go Web development, in order to achieve more efficient and flexible routing functions, many developers choose to introduce third-party libraries such as httprouter and gorilla/mux. However, in Go 1.22 version, the official has significantly optimized http.ServeMux in the standard library, which is expected to reduce developers' dependence on third-party routing libraries. 1. Highlights of Go 1.22: Enhanced pattern matching capabilities Go 1.22 implements the highly anticipated proposal to enhance the pattern matching capabilities of the default HTTP service multiplexer in the standard library's net/http package. Existing multiplexers (

Mastering Go String Manipulation: Performance-Boosting Techniques

The author invites you to purchase my books on Amazon. Don’t forget to follow my Medium account and give your support! Your support is crucial! String operations are the foundation of programming, and in the Go language, performing these operations efficiently is crucial. As a Go developer, I understand that the way the Go language handles strings is unique and requires careful consideration for optimal performance. Go language treats strings as immutable sequences of bytes. This immutability brings benefits such as thread safety and predictable behavior, but it also means that any modification to the string creates a new string. This feature can cause performance issues if not handled properly, especially if string manipulation is frequent. One of the most common string operations is concatenation. exist

Reducing Garbage Collector Pressure in Golang

In high-performance Go applications, excessive memory allocation and deallocation can severely impact performance, putting unnecessary pressure on the garbage collector (GC), resulting in increased latency and reduced efficiency. This article will introduce how to use object reuse technology and sync.Pool features to reduce GC pressure. This article was inspired by a LinkedIn post by Branko Pitulic, which highlighted the importance of optimizing memory usage in Go applications. 1. Understand the problem Go's garbage collector is responsible for automatic memory management. However, when an application allocates and frees memory frequently (especially on the heap), the GC has to work harder, resulting in: Increased CPU usage; Execute temporarily during GC cycle
