"Although the struct Data contains a [1024]int array, which is 4 KB (assuming int is 4 bytes on the architecture used)"

Huh,what?

I mean, who uses 32b architecture by default?

Most C/C++ compilers have 32b int on 64b arch. Maybe the confusion comes from that.

Also it would be 4KiB not 4KB.

What?

Article is about the Go compiler. On 64 bit arch Go int is 64 bits.
