Re: system performance
Hi,
Your data shows something wrong with your system. system process(%sys) should not consume 91% of cpu cycles. Ideally system process consumes between 20 to 30%.
Find out which process consumes more resources using top or glance and restart or kill those process.

Re: system performance
Shalom,
You system looks a bit busy.
Most systems do have a little idle time.
Your system also has a lot of system process time, versus what I'd expect where some user applications like databases and such would use more CPU time.
So I'd say slightly abnormal, but it all depends on how you use your system.
Is system response time sluggish? Are users complaining?

Re: system performance
'sys' is taking up too much in resources and leaving little for 'usr'. You need to see why.
Could be something is hung....run top real quick and see who's taking sitting at the top hogging the box and address accordingly.
Could be your parms are really not right and contributing to a poor application running problem.
What is your
dbc_max_pct, dbc_min_pct,
nproc,
maxuprc,
ninode,
maxdsiz,
shmmax
vx_ninode set to for a start?
How much memory on this box?
Just some things to look at,
Rgrds,
Rita
