I don't see anything extremely wrong here. Note that 51% of your CPU is
being spent in interrupts. Which means you're fast switching and
everything is going well.
There is obviously just a lot of traffic going on here that it has to
deal with. Now if it said something like 99%/1%, I would be a little
concerned.
