Calculation:
Maximum SDTI bandwidth / Actual Bandwith = real time transfers:
110MB/s / 18.4MB/s = 6 real time transfers.
Note: This number is the maximum that the network connection can
support. Of course it is also necessary that the XT[2] where the material
is stored has enough local disk bandwidth to feed the network accesses,
on top of its own local channels (cfr point 4. Max. RT Channels)
