Default On what does Kainy latency depend on?

Hey,

im going to get a gaming tablet thing(Gpd g7 or archos 2).
Im wondering on which pc streaming with kainy depend on.Is there a way to reduce latency?Do 8 core CPU help?

Also: do all devices(also smartphones) do have same latency?Or do specific devices do better than others regarding latency?

And do i need a special router or any will do?
