I think I have posted something like this before, but anyway...

Here's a two part story of how to optimize memory usage of a Go application just by reshuffling fields in structs.

Part one provides some theory on this matter, while part two has some benchmarking results.

I'm not trying to say that you should run and reshuffle fields in all your Go structs right now. Especially, if you're satisfied with the memory consumption of your app - sometimes it makes sense to optimize for readability or just store pointers in structs.

However, these articles describe some details of how memory allocation works in Go, which you may find interesting.
