Recently I've been testing my PS4 connection a lot and seem to be getting around 50mb download with 6mb upload (getting around 74mb on my phone using wifi), but when downloading large updates/games etc it flies though parts of the download, and then goes extremely slowly. When it's downloading slowly it still shows my speed at 50mb? At times I have to pause and resume a few times for the download to proceed quicker, or sign out and back in. I don't quite get it, PS4 is wired and at the time there were no other devices using wifi.
