First of all, the netmask is wrong. You should either leave it out, or
set it to 255.255.255.255

A smaller MTU means more overhead, so things will be slower. However,
some PPP drivers can choke on large MTU packets. Either way it doesn't
matter, because the MTU is negotiated, so the client will get whatever MTU
it asks for. You've got to hope that the client asks for a MTU that is
best for it.
