That reason could be compatibility.

If you see slower response then perhaps something is wrong.
Perhaps you should call their support and verify that you do not have a 
mismatched duplex setting?

Mismatched duplex can come from misbehaving autonegotiation or that one 
end is set to full-duplex while the other end is set to half-duplex, or, 
one end is set to full-duplex and the other end is set to auto-negotiate 
(which results in falling back to half-duplex).
