Resolution Note:
After an exhaustive investigative profiling process we have concluded that it is not reasonably feasible to address the performance issues in mono's HttpClient web stack. We've isolated the source of the problem to be unfortunately fundamental to the way the code was written and would require a complete refactor to address. Our recommendation is to use the better performing UnityWebRequest for now until we address this issue in a later release.
