using System; 
using System.Diagnostics;

public sealed class Program 
{
    struct S
    {
        long l;
    }

    public static void Main() 
    {
        Stopwatch sw;

        S[] i = new S [100000];

        sw = Stopwatch.StartNew();
        for (int nn = 0; nn < 10000; ++nn)
        for (int n = 0; n < i.Length; n++) 
        i [n] = new S ();

        Console.WriteLine(sw.Elapsed + "\tM");
        Console.WriteLine (i);
    }
}

I don't really know which part causes the slowdown but here the numbers
