Go is a concurrent system programming language the strength is its ability to produce scalable and reliable software. In your example you set the MAXPROCESS config high but don´t use gorotines to make it parallel/concurrent that´s like feature cutting and that´s no scenario where the language can show his nature of working.

This is not correct, http.ListenAndServe will use a goroutine for each request. Also the garbage collector will use multiple CPU cores when given them.
