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.
