Golang on GAE is so fast!

I became a trusted tester for Google App Engine/Go.
So, I benchmarked this. And I compared GAE/Golang with GAE/Python.

I checked calculating time for make prime numbers(<10000).

result

times	Golang	Python
1st try	49.2	807.3
2nd try	49.7	833.0
3rd try	49.0	830.6
4th try	50.0	806.7
5th try	49.2	782.2
average	49.42	811.96

This values means MilliSecond.
You can understand that GAE is so fast.

I used this code.

Golang

package test4golang 
 
import ( 
    "fmt" 
    "http" 
    "os" 
    ) 
 
 
func init(){ 
    http.HandleFunc("/",prime) 
} 
 
func prime(w http.ResponseWriter, r *http.Request) { 
    startTimeS, startTimeM, _ := os.Time() 
    for i:=1;i<10000;i++ { 
        for j:=2; j<int(i/2); j++ { 
            if i%j == 0 { 
                break; 
            } 
        } 
    } 
    finishTimeS, finishTimeM, _ := os.Time() 
 
    finishTime := finishTimeS*1e9 + finishTimeM 
    startTime := startTimeS*1e9 + startTimeM 
 
    fmt.Fprintf(w,"%d , %d<br> %d",startTime,finishTime,finishTime-startTime) 
    return 
}

Python

import cgi

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from time import time

class PrimeNumber(webapp.RequestHandler):
    def get(self):
        i=0
        j=0
        startTime = time()
        while i<10000:
            j = 2
            while j<(i/2):
                if i%j == 0:
                    break
                j +=1
            i += 1
        finishTime = time()
        self.response.out.write(finishTime - startTime)

application = webapp.WSGIApplication([
                        ('/',PrimeNumber)],debug=True)

def main():
    run_wsgi_app(application)

if __name__ == "__main__":
    main()

Corrected
