Why does the simple Hello world program take 2 MB after compilation?

Because golang has a runtime that includes a garbage collector, goroutine scheduler etc

Please take a look here: https://stackoverflow.com/questions/28576173/reason-for-huge-size-of-compiled-executable-of-go

You can probably make it much smaller by just stripping the binary, and for those cases where you want it to be even smaller, you can always use UPX (but that comes with a price in the form of slower startup and higher memory usage).

It is one of the first things that people who start golang wonder, also another feature that makes this language unique.

Executable size for small programs is not a top priority in gc.
So if you care about executable size (e.g. if your code runs on microcontrollers,
or WASM), you may want to have a look at https://tinygo.org/ .
