How is Load Average calculated ?

Question

My XG load average is a number between 1.0 and 2.0 mostly sitting at 1.3. This is strange for me because CPU idles at 2-3% most of the time. Normal Linux system with such cpu usage will have load average of less than 0.1. 
 As XG has a Linux kernel (modified or not - i don't know) - it should calculate load avarage similiary, or not ? 
 Does anybody know something about that Load Average meaning ?

Hi Slawek, 
 Online definition for Load average is the average system load calculated over a given period of time of 1, 5 and 15 minutes. The maths is same for the XG firewall, based on the fact that it runs on a Linux kernel. If you have dual-cores CPU running the XG firewall, then the load average is normal. 
 To check the numbers of cores, you can execute the following command in the Device Console: 
 console> system diagnostics show cpu 
 Thanks,

You can check the linux community on the load value.
