Ps4 download rate slower and slower?

So, every time I have the problem when I start a download on the ps4 that the speed is initially in the normal range but the longer the download runs the slower the speed. Have already tried the trick with the DNS and MPC, but nothing helps

Is your internet just maybe slow?

So it could be that he downloads the update from the internet at the beginning but he has to write the downloaded file to the hard drive and that could take a little bit longer. But I can't guarantee you either.

Is not the best but the speed at the beginning of the download would be absolutely sufficient, but as it slows down, it takes forever. The speed on the pc and mobile phone is also much faster

But then I'm surprised that this is only at 1GB appearance and with progress even slower because the pure download should actually remain the same fast
