It seems like downloading a file via /files/data/..., the download is incredibly slow. Not entirely too sure why, or where to look:
I know our connection to the phab instance we have is much faster, considering it takes only a few seconds to pull a git repo ten times the size of the image above.
Few notes: Files are stored on the server via the file backing store on their own volume. During these tests the volume was not busy/loaded.
