The system load is far too high compared to the user load.

You should investigate what processes and what system calls are consuming that much kernel time.

Start with running
Code:
prstat -mZ -n 30 -c 10 2

during a peak period.

As was suggested, I've requested our DBA's to investigate what they can do from their end... it met with a lot of reluctance, but I think they will have a look at it as well. Smilie
