I am also encountering the problem of scenes stopping every 5 seconds or so on my Oculus Quest 2 running DEOVR.
On my HPReverb, I don't have this problem. It is connected to CDN Pop Location = Beauharnois-4,CA. I am getting 20.5 Mbps streaming speed when running SLR App speed test on my PC so everything is as smooth as a moist pussy.
When I use my Oculus Quest 2 (standalone) and run a speed test from the SLR menu, I only show 6.4 Mbps streaming speed. It is connected to CDN Pop Location = Beauharnois-3,CA (unlike Beauharnois-4,CA when running on my PC). I am located in a Philly, PA suburb, so it makes me think that maybe I should be connected to a location on the East Coast, but I really don't know and I don't know how to change it anyway. The scenes use h265 codec and stay locked at that. Since the Oculus is on the same home network as my HPReverb, I don't see how anything could be throttled by the ISP. It seems like the Oculus itself is throttling it, but I really don't know where any setting is for that within Oculus.
I would really like to run SLR through my Oculus at various times instead of being tethered at my PC to run my HPReverb so any ideas would be greatly appreciated.
