The IDE for professional development in Go
GoLand
One of the design choices Google made when developing Go was to abstract memory management away from developers so they could focus on what really matters – writing code. Things like escape analysis and garbage collection are thus automatic, and the Go compiler works in almost mystical ways.
That’s one of the best features of Go, so long as your program works. But when memory issues arise, and you need to demystify the process to optimize it, that’s when the perspective shifts and the mystery is no longer so appealing.
In this article, we’ll explain one of the most confusing performance optimization problems – escape analysis, i.e. how the compiler decides what stays on the stack, and what moves to the heap. We’ll cover what escape analysis is and how it works, what the most common escape cases are and how to inspect them, why inspections might be hard to use, and even how GoLand can perhaps help with that.
