Are there any performance issues when running Golang applications on an elastic beanstalk?

Question

I am trying to compare hello world's simple http server go. I did 2 tests:

• Using an instance of amazon ec2 - m3.medium
• Using Amazon's elastic beanstalk - also with one instance of m3.medium

In the first setup, I could get up to 18k req / sec. On the second, 1.6k req / sec.

Source Code: (from: https://golang.org/doc/articles/wiki/ )

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hi there, I love %s!", r.URL.Path[1:])
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

Is there any explanation for such a huge difference in performance?
