Introduction

In boxing, the time taken is much longer.

Demo

using System;
using System.Collections.Generic;
using System.Diagnostics;//For Stopwatch
class Program// w  ww.  j  a v a2 s  .co  m
{
    static void Main(string[] args)
    {
        List<int> myInts = new List<int>();
        Stopwatch myStopwatch1 = new Stopwatch();
        myStopwatch1.Start();
        for (int i = 0; i < 1000000; i++)
        {
            //Adding an integer to a list of Integers. So, there is no need of boxing.(Advantage of Generics)
            myInts.Add(i);
        }
        myStopwatch1.Stop();
        Console.WriteLine("Time taken without Boxing: {0}",
         myStopwatch1.Elapsed);

        //Now we are testing :Boxing Performance

        List<object> myObjects = new List<object>();
        Stopwatch myStopwatch2 = new Stopwatch();
        myStopwatch2.Start();
        for (int i = 0; i < 1000000; i++)
        {
            //Adding an integer to a list of Objects. So, there is need of boxing.
            myObjects.Add(i);
        }
        myStopwatch2.Stop();
        Console.WriteLine("Time taken with    Boxing :{0}",
           myStopwatch2.Elapsed);
    }
}
