I am not sure the buffer size used by the Squeezebox driven TranspOrt. Its never been an issue with a wired or even wireless connection in my experience, but I will do some digging in case people with latency issues in their home networks have questions.It's a performance issue and not just latency. All computer buffers to enhance performance.
Bryston BDP, Audirvana, JRiver ... they all buffers at least 1st track before play. If you ask Lukasz about buffering he will understand. I'm interested how much his transport buffers before play.
