I've been using this with a Raspberry PI based music server on my boat. The server has over 38K tracks. While I guess I should expect this system to be slow to update on a large music library  I often find that in the middle of paging through music  the connection to the server is lost and I have to reconnect and start from the beginning again. After 4 or 5 times it can get pretty frustrating. For me  the Logitech Android client works the best (I think it does a better job of caching the music library)  but unfortunately it won't work with Android 5 and above. I've tried some of the others  and they were worse  so it's the best of a bad lot!
