The official standard Go compiler make special optimizations to hash 4-byte and 8-byte map keys.

So, map[[8]byte]T is more CPU-saving than map[[5]byte]T.

The same, map[int32]T is more CPU-saving than map[int16]T and map[byte]T.

✅ How to calculate stack size of a function?

Go calculates the maximum stack size a function will use at runtime at compile time.Code branches will all be considered in the calculation, even if some of them won't be executed.We can display function stack main sizes using the -S compiler option.

$ go run -gcflags=-S frame.go
...
... TEXT "".bar(SB), ABIInternal, $5024-32
...
... TEXT "".foo(SB), ABIInternal, $10056-8
...
... TEXT "".main(SB), ABIInternal, $64-0
...
... TEXT "".duck(SB), ABIInternal, $16024-0
...

• the stack size of the bar function is 5024 bytes.
• the stack size of the foo function is 10056 bytes.
• the stack size of the main function is 64 bytes.
• the stack size of the duck function is 16024 bytes. Please note that, although the duck function is a de facto dummy function, its frame size is not zero. This fact will be made use of in a code optimization trick shown later.

In the official standard Go compiler implementation, each value of the following kinds of types always contains only one part:

✴️

 boolean types

✴️

 numeric types (int8, uint8, int16, uint16, int32, uint32, int64, uint64, int, uint, uintptr, float32,
float64, complex64, complex128)

✴️

 pointer types

✴️

 unsafe pointer types

✴️

 struct types

✴️

 array types

And a value of the following kinds of types always may contain one or more indirect parts:

✴️ slice types
✴️ map types
✴️ channel types
✴️ function types
✴️ interface types
✴️ string types
