OK. Sorry, for the late reply, I wasn't on the good machine these last days. I'm not sure to understand what you mean. I've been googling a bit about wicd (which I already heard about), and I found it was kind of a network manager, in some ways, but I didn't see anything telling I can use it with netjack. Perhaps I misoriented you when typing "reloading netmanager", I was actually talking about: jack_load netmanager and jack_unload netmanager commands, which are linked to jeckd and netjack. by the way, I'd like to benchmark a bit my latencies today, as I'm quite sure (I feel it, actually) they are bigger with jackdmp/netjack2 than they were with jack 0.116/netjack1. Not sure it comes from netjack or from jackdmp, or whatever. I use it with slow mode, which is, if I understand well, the best way to keep latencies smaller as possible on the master machine. What do you suggest me to use for the benchmarks? Thanks.
