Hi sun managers
I have a Sunfire V120 that's running very slow.
The shell response is slow.
Applications running on the system are reporting a backlog of
outstanding tasks due to the system running slow.
I've run prtstat and memory / cpu are both ok ...
> prstat -ac
NPROC USERNAME SIZE RSS MEMORY TIME CPU
96 root 1723M 1327M 68% 68:02.51 37%
1 mysql 52M 28M 1.4% 4:42.27 2.7%
16 nobody 69M 40M 2.0% 0:09.55 0.0%
1 daemon 2528K 1808K 0.1% 0:00.00 0.0%
Total: 114 processes, 470 lwps, load averages: 7.81, 6.88, 7.21
Iostat doesn't seem to report anything either ...

I am also running software raid (mirrored disks), that from metastat are
all reporting 'State: Okay'
What else can I do to find out where the blockage is?
Thanks
Andy
