SV: SV: SV: Multiple cpu?

[Anders Andersson, IT]

Hmm, now I feel stupid but I have to ask.
Whats the differense between instances and child processes?
You all probably figured out my level of expertice  =(
but this is something I relly need to understand.
My guess from the begining was thats with 2 cpu MS would be 
able to scan faster. But know Im not sure If I should spend the
extra money.
Does 2 cpu demands extra config or will it handle it by it self?

Kind regards
