Yes it is. Squid can possibly use the whole CPU core cycles, but each
worker is a single threaded process so it cannot make use of more than
one core.
If you are using rock cache_dir they use a separate disker proces to
manage teh disk I/O so it may be worthwhile allocating a core to that
process as well as the main worker(s).
