does oracle support more than one CPU for SuSE Linux 9.1 or 9.2 or 9.3 Professional Linux

We have some performance Problems due to heavy load in an oracle database
10g.
Our Server is Hewlett Packard Proliant ML380 OS: SuSE Linux Professional
9.1.
We have one Processor installed and 4 Gigabyte RAM.
Would it help to install another Processor increasing the performance?
Does Oracle support really 2 Processor Systems?
What could be the expected gain?

regards
Maximilian
