How much memory is needed to run 1M Erlang processes?

Less that 1 GB... that's impressive! Now I'm wondering how much memory Go or Java would require.

It is in the original article [1], though I was made aware that Go implementation is also incorrect as `defer` in it make the memory usage to substantially raise. So instead of:

        defer wg.Done()
        time.Sleep(10 * time.Second)

In original article it should be:

        time.Sleep(10 * time.Second)
        wg.Done()

And memory usage will drop about 2x. I am no Go nor Java developer so I cannot say anything more.
