c# - RestSharp 与 WebRequest 相比的性能问题

Question

我在restsharp客户端中发现一些性能问题，我在PerformanceRequest2函数中使用RestSharp向一些restful API发送请求，并在PerformRequest中使用WebRequest使用正常的.net请求

PerformRequest 的平均响应时间为 75 毫秒，而使用 RestSharp 的 PerformRequest2 的平均响应时间为 300 毫秒。这是restsharp的一些限制还是我们使用restsharp的方式做错了

private static void PerformRequest2(string requestData)
{
    var request = JsonConvert.DeserializeObject<ComplexClass>(requestData);
    var client2 = new RestClient("URL");
    var restRequest = new RestRequest();
    restRequest.Method = Method.PUT;
    restRequest.AddHeader("Content-Type", "application/json");
    restRequest.AddHeader("Authorization", string.Format("Bearer {0}", token));

    restRequest.AddJsonBody(request);

    var restResponse2 = client2.Execute(restRequest);
    if (restResponse2.StatusCode != HttpStatusCode.OK)
    {
        throw new Exception("error");
    }
}


private static void PerformRequest(string requestData)
{
    var request = JsonConvert.DeserializeObject<ComplexClass>(requestData);
    var webRequest =
        WebRequest.Create("URL");
    webRequest.ContentType = "application/json";
    webRequest.Method = "PUT";
    webRequest.Headers.Add(HttpRequestHeader.Authorization, string.Format("Bearer {0}", token));
    using (var streamWriter = new StreamWriter(webRequest.GetRequestStream()))
    {
        streamWriter.Write(JsonConvert.SerializeObject(request));
        streamWriter.Flush();
    }
    var httpResponse = (HttpWebResponse) webRequest.GetResponse();

    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var result = streamReader.ReadToEnd();
        if (string.IsNullOrEmpty(result))
        {
            throw new Exception("error");
        }
    }
}

我从以下链接得到了答案:

应用修复后，使用 Restsharp 和 httpwebrequest 的性能相当
