Hi...

For buffer size I use 65536...

The optimisations should work partly especially the realtime thing (chrt command) due to less number of cores.

I use an e-sata connected SSD for playback so I use MPDroid on my phone or Theremin on Mac for playback.

Devialet does not use/need the USB power so I would take away the ifi power and use just the data side of Gemini cable straight between RPi2 and Devialet.

Another suggestion (I dont know how it will respond on RPi2)
install HTOP for easy process management (apt-get install htop)
run it and kill everything which does not make sense (not the mpd or upmpdcli threads but especially anything with php5 and avahi (you will not be able to reach the web interface until the next reboot)
stop the squeezelite as well if you wont be using it for your listening session.

also run
renice -n -15 -g $(pidof mpd)
to make it a rude (!) application.

Anything goes wrong, just reboot.

Here is a screen shot of my HTOP screen after optimisation
