[LAU] NetJack2 and Fast mode

Hello, I recently switched to jackdmp and, as a result, to netjack2. It looks like it works fine, though I didn't had much time to run it very long. However I couldn't make it work in "fast mode", so I was wondering what are the requirements to use that mode? Personnaly, both slave and master have gigabit ethernet cards, on a local network, the master runs with a Focusrite Saffire Pro40 with FFADO 2.1 (unstable) and the slave do not have any soundcard enabled. I use it only for transport synchronization and midi message sends. (I wonder if I should better use aseqnet and something like jack_udp or something for such "light" purposes) Thanks.
