CPU Load

[Global Server Operation]

I have a N4000 server with 6 CPUs. Data base running is Progress and we have 421 printers.
CPU 0 .37
CPU 1 7.71
CPU 2 9.02
CPU 3 7.45
CPU 4 6.31
CPU 5 10.95

Via top, the load for CPU 0 is consistently lower than the load of remaining 5 processors which tend to stay closer together in value.

Is this situation unusual? Is this something that can be controlled? or Is this something that is application driven? I'm wondering could this impact performance because cpu 0 is not used as much as the other.
Any feedback will be welcomed.

This can be managed with PRM.

However, the OS is supposed to do a better job than that balancing resources.

You might check your application to make sure that smp(multiple processor) featurs are enabled.

This, being a snapshot might be misleading. I'm attaching a script that lets you collect data and obtain averages over time.

Which version of HPUX are you running?

What about the list of processes listed by top?
Perhaps you have 5 processes using a lot of CPU time and 'bound' to the 5 processors, while other processes are handled by CPU0?
It is unlikely considering you are running database in this server, but that's something to start with ...

The OS is 11i. The top 5 processors are dabase related processes.
