How to get REALLY fast benchmarks
time to read 2 min | 231 words

I was very excited when I tried this code, it produced amazing performance:

private static void LoadDataFor(string searchPattern)
{
    foreach (var file in Directory.GetFiles("Docs", searchPattern).OrderBy(x=>x))
    {
        var sp = Stopwatch.StartNew();
        var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost:8080/bulk_docs");
        httpWebRequest.Method = "POST";
        using(var requestStream = httpWebRequest.GetRequestStream())
        {
            var readAllBytes = File.ReadAllBytes(file);
            requestStream.Write(readAllBytes, 0, readAllBytes.Length);
        }
        Console.WriteLine("{0} - {1}", Path.GetFileName(file), sp.Elapsed);
    }
}

Can you figure out what the fatal flaw in this code is?
