I have an old Sol 2.6 domain on our E10K and recently the CPU is maxing out
more than usual. It's a high load oracle box to begin with for sure. I
don't see a lot of iowait on the box but iostat shows, in my opinion, a
high asvc_t service time on my root disk.

Can anyone suggest a way to further diagnose why my average service time is
above 60 on my root disk??
