Some users are complaining of poor performance on a brand new server. The only running on this machine is Oracle 10.2.
At first glance everything looks ok: load is minimal, nothing in logs. The only thing i can find is that vmstat is complaining of lots of swapping in and blocked processes. Where should I begin troubleshooting this one?
# vmstat -S 5 5
