I assume that MB=Mega Bits (and *not* Megabytes).

If that's the case: is the squid NIC 1Gbps? if so: these are usually
full-duplex (and = to clients connection speed), so: no, you will not
have a real benefit from adding another NIC, but, if you insist, you
could do it without changing most of your configuration, by adding two
NICs together with bonding (and a port-channel on your switch, if it
support it).
