As I have no knowledge about ethernet cards except for the obvious (1 gigabit), I was hoping, if some of the more tech savvy guys could give me hint what to buy without spending more than necessary. :-) But I don't want to be cheap either, where this could boost the performance, so, here we go ...
So far, I have been using the built in ethernet ports of my two slave PCs and the (upgraded) Mac pro 2009 model. I connect one of the slave PCs directly to the second ethernet port of the Mac! For this connection I created a dedicated network. The Mac's first ethernet port and the ethernet port of the second slave go to a Fritzbox 7390 with four gigabit lan ports.
What model would be a good choice to buy as dedicated NIC for the PCs? Is it worth it, if I buy it only for the PCs, as I have no free PCIe slot left on the mac pro (actually, there is one, but it is not accesible due to the second slot of my RME Madi FX card)? Would a dedicated switch (what brand?) be better?
The thing is, all is working decently and I can get about 32 audio streams from each slave. But I suppose, it could get better, can it?
