The main Squid process is a single process and can use at most one CPU. This is by design of Squid. Some CPU may be used by the diskd/aufs I/O slaves but not very much and it is doubtful this outweigths the general performance penalty of enabling SMP support in the kernel. The big benefit of a additional CPU is if you have CPU intensive redirector helpers such as SquidGuard with a large regex list etc, or if the same server needs to run other CPU intensive applications while the proxy is at peak usage.
