It can easily. Each type of traffic; accelerated, standard proxy, backend
traffic; work on a different ports.

Backend server can be anywhere. So long as the squid machine can open a
TCP connection to it.

Performance is limited by several things. Many of which have been stripped
away in recent versions. Having traffic run both in and out of the same
NIC will only cut you to ~1/2 its max throughput as the very worst case
scenario where every client requests unique no-cachable content.

Neither for nor against. It's one of the common setups.
