Logical CPUs :)
To make sure the test config is fair to both native and xenu.
You should make sure the native and xenu are using the same number of LPs.
For example:
If native linux has 4 LPs, you should enable "vcpus=4" in the config file.

Another factor may impact the performance testing is the service processes.
It would be better to disable most unnecessary services in xenu, domain0 and 
native linux.
