Test case:

using System;
using System.Collections.Generic;

namespace ConsoleApplication9
    class Program
        static void Main (string[] args)
            Random r = new Random ();
            List<string> list = new List<string> ();
            for (int n = 0; n < 50000; n++)
                list.Add (r.Next ().ToString ());
            DateTime t = DateTime.Now;
            list.Sort ();
            Console.WriteLine ((DateTime.Now - t).TotalMilliseconds);

Tested in the same Windows box, this test case takes 10x more time in mono to
