.SH USAGE EXAMPLES
If for instance the Ethernet NICs have multiple queues for both receive and transmit, each with its own IRQ, the Ethernet IRQs can be associated with a CPU socket:
.TP
-.B tuna -S 2 -i -q 'eth*' -x
+.B tuna isolate -S 2
+.TP
+.B tuna spread -q 'eth*' -S 2
Move everything off the CPUs in socket 2, then spread the IRQs for the Ethernet devices across those same CPUs.
