Hi

AFAIK

By filtering U decide which destination traffic will be label switched and 
whitch will remain as
IP switched .

i guess it has nothing to do with performance .

Minimize the nbr of label also reduce the converence time of LDP .

make sure that the same policy of filtering applied to all nodes .
