Gilbert it is fair to say that Roon puts a strain on networks, especially when streaming 24/96 as it is pushing data in multiple directions at the same time (even local Flac files).
I redesigned my home setup as I moved from mp3 and some FLAC streaming, as I could always stream mp3 perfectly and flac would often skip or pause, and I agree it was very frustrating.
Remember with Roon everything is brought in by the Roon server, processed (where asked) and sent back out to the the endpoints in pretty much real-time.
Your Roon server and network has to be up to coping with this and this is where complaints come in.
I still have the occasional skip and pause in my setup but they tend to be occasional now and due to spouse friendly decisions I made to move gear away from the optimal places.
I am not claiming that Roon is perfect in any way, but it requires effort and the hardware setup at the beginning to reap the rewards in enjoyable listening time.
