In order to run a few benchmarks on my newly installed 13.04, I wrote the below fibonacci script in python. It basically accepts a number and starts crunching fibonacci numbers that many times:

#!/usr/bin/python

import time

from time import time



def fibo(n):

    a,b,i=0,1,0

    while i<n:

        #print b

        a,b = b,b+a

        i+=1





if __name__ == "__main__":

    s=time()

    fibo(1000000)

    print round((time()-s)*1000,0),"ms"

However, when the fibo() function is called with 1 million as parameter, the python seems to hang. While, this similar code in java runs instantly:

class fibonacci

{

    private static void fibo(int n)

    {

        int a=0,b=1,i=0;

        while( i<n)

        {

            //print b

            int t=a;

            a=b;

            b=b+t;

            i++;

        }

    }   



    public static void main(String[] args)

    {

        float s=System.currentTimeMillis();

        fibo(1000000);

        System.out.println( (System.currentTimeMillis()-s) + "ms");

    }

}

What is the reason for this? Is python inherently that slow or is something wrong with my raring installation ?
