I would not expect named to spend much time in the kernel. I expect that it
spends most of its *CPU* cycles looking through its in-core database.
Serving 60 requests/second involves some 180 system calls (assuming
select, read and write for each request). Not a huge deal.
Still, I'm surprised that the number is so low.
