The required bandwidth can be easily calculated:The streamer side is limited to 100 mbps. I don't understand this obsession with high-capacity switching. Last time I looked, and I stream at DSD256, the traffic out of the fibre port to my hifi was 34 mbps.
DSD256
44,100 x 1 bit x 256 x 2 (stereo) = 22,579,200 bits = 22.6 Mbit/s
The reason you have measured more is that even more data goes over the line than the pure music signal.
DSD1024
44,100 x 1 bit x 1024 x 2 = 90,316,800 bits = 90.32 Mbit/s
The 100 Mbit/s would no longer be sufficient here.
The point is that a switch with a bandwidth of > 10G must meet higher specifications. This is logical, as a higher bandwidth must have less latency and jitter for the data transport to work.Why the need for 10 gb switches?
A switch that meets the specifications of 10G and more has significantly better components, less jitter and less noise. Of course, it always depends on the implementation in the device.
