LSWS on a VPS

[alberto]

We intend to install LSWS on a Virtual Private Server (VPS).

Hence we're not sure what would be the appropriate version os LSWS for us...

How should we count the number of CPU cores? Is it the real hardware number or is it whatever the VPS can see?

Does it really matter if we pick the LSWS for 1 core and later install it on a Dual core machine? Will it really affect the performance?

Our VPS is the V-Elite on http://virpus.com/hosting-solutions/vps.html.

The actual hardware is a big server, with several CPUs, each of them with several cores (need to check the actual number).
