Hi Per, could you have a quick look if these stat improvements are expected as a result from this CL: https://codereview.webrtc.org/2268163004 
Thanks!

There are two possible reasons for speedup. First, eliminating the int conversion itself is good. Second, this code is most likely vectorised now, it might not have been before.

Wow, that is a much bigger improvement than I would have anticipated. I think this is fine though, and it is an improvement that could have been related to that CL, so I'll close the issue.
