На каком языке HTTP WEB REQUEST быстрее всего?

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(sender);
WebResponse resp = null;
req.Proxy = null;
req.Method = "GET";
req.Timeout = 1500;
req.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
req.UserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36 OPR/27.0.1689.66";
req.Headers.Add("Cookie", coociesStr);
req.Headers.Add("Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4");
resp = req.GetResponse();//задержка 400-800мс (иногда превышает таймаут)
StreamReader sr = new StreamReader(resp.GetResponseStream());
string str = sr.ReadToEnd();
sr.Close();
