I don't think this is true. You might not have an aggregate bandwidth issues,
but given the burstiness of TCP and the typical switch buffer depth
(64 frames is a typical number), it's very very easy to lose packets in your
switch even on a relatively quiet network with no downconversion. (Witness
the rise of DCTCP, made especially for internal traffic on this kind of
network.)
