The interrupt rate only changes if traffic goes out on the queue, and so if whatever applications you use don't utilize the core the queue is bound to, then the interrupt rate won't change. Or are you confused about the units? I know ixl(4) uses usecs instead of Hz, so ix(4) should probably change to use that at some point.
