Spikes because of the very poor performance of UnityWebRequest.Get() on Android.

UnityWebRequest.Get () on Andoid caused a spike of 20 ms or more.

I want to solve this problem in order to load data with Background.

Please tell me the solution to this problem.

Unity version is 2017.3.1f1.

If there are some mistakes in English, I’d like to apologize.

 public void DoRequest(string url, Action<string> onComplete)
 {
     UnityEngine.Profiling.Profiler.BeginSample ("Request.Get");
     var request = UnityWebRequest.Get (url); // very poor perfomance.
     UnityEngine.Profiling.Profiler.EndSample ();
     StartCoroutine (Exec(request, onComplete));
 }
 private IEnumerator Exec(UnityWebRequest request, Action<string> onComplete)
 {
     yield return request.SendWebRequest ();
 
     onComplete.SafeInvoke (request.downloadHandler.text);
 
     request.Dispose ();
     request = null;
 }
