Go’s Garbage Collection: How It Works and How to Optimize It

Garbage Collection (GC) is an essential feature of modern programming languages, and Go (Golang) is no exception. It automatically manages memory, freeing up unused memory so developers don’t have to manually handle memory allocation and deallocation. Understanding Go’s Garbage Collection and how to optimize it can help developers improve performance, especially for applications with large memory footprints or high concurrency.

In this article, we’ll cover Go’s GC, explain how it works, and explore strategies for optimizing its performance, from basic to advanced.

What is Garbage Collection?

Garbage Collection is the process by which a programming language’s runtime automatically identifies and frees up memory that is no longer being used by the program. This means you don’t need to manually allocate or deallocate memory, reducing the chance of…
