Regression
No
When receiving JSON via UnityWebRequest, memory is severely inflated even if small file (about 1MB) is used
To reproduce:
0) Download "downloader.cs"
1) Create a new project and import the script in
2) Edit the script so that the coroutine would be launched on Start()
3) Attach the script to any object in the scene
4) Open the profiler and mark it on Memory section
5) Play it
Expected: Minimal jump in memory after downloading
Actual: The memory differs in roughly 400-600 MB (depends on version)
