Hi Andrew,
from what I can see from those numbers I guess you are using some sort of
multipath.
What's the software of your choice?

Then I hope you are connecting through a connection pool otherwise this can
be a good reason for the system cpu time.

- What is every connection doing?
- may you reuse your connections without opening and closing them?

Your I/O is not too bad and I cannot really spot a system problem. I'd
investigate your application before going back at the operating system.

At this point a good place where to look is statspack.
