Although this would technically work I don't see any gain here - just more
overhead. IMHO two Squids on the same server won't make things go faster
than a single Squid.

If your proxies are not fast enough (CPU, network bandwidth, etc.) then
consider setting up Squids on different servers and put a decent hardware
load balancer in front of it. We use a Foundry load balancer and four
Squid nodes here.

Btw, you can use multiple cache directories (cache_dir) in case you want to
use different hard disks to speed up the disk cache.
