SolutionYour CPU's have hyperthreading enabled. That is a virtual, software CPU, built into the hardware CPU. By default, it is enabled in the BIOS.
The OS see's the number of CPU's based on the virtual count.
4 hardware cpu's equal 8 top cpu's in this scenario.
Gets you 60% performance bump over older cpu's.

Re: redhat - CPUs - show double what is installed
If the system has hyperthreading than it will show 1 CPU as 2
eg if ur system has 2 cpu it will show as 4.
In order to have alook at the real no. of CPU's do
cat /proc/cpuinfo
Cheers
