A quick comparison on Intel cards and cheap switchs shows the 10Gbe RJ45
port costs double on the adapter. Choose wisely, I'll go with the switch
over four workstations. And having lots of NICs in the same server may
not scale well : too many interrupts, under usage of ring buffers and
queues, lots of kernel tasks.
