[PROBLEM] Airplay stuttering since moOde 9

[cramcram]

Here are some stats from my network (Pi to Router). It's just a single Router and the dwelling is timber framing and drywall, no plaster w/metal lath etc. I ran some ping tests from three Pi's each in different locations. One of the Pi's was connected via Ethernet another via WiFi 2.4GHz and the other via WiFi 5 GHZ.

Thanks for the data. So my results are approx. the same as yours. Anythings else I could try? Sorry for insisting on my problem, but on 8.3.9 Airplay worked really reliably in my setup with Wifi. The only thing I changed is the update to moOde 9 version.
