Excuse my ignorane with MP platforms, but does Solaris 2.6 automatically
use the 2nd (or more) processor for regular tasking or does each used
application have to be coded to use a particular/multiple CPUs?

In other words, should I decide to buy another CPU for my SS20, will I
notice a difference with performance in X or normal applications?
