First of all, why would you expect there to be a difference in performance?
Both senerios use MPLS forwarding.  The only difference maybe the presence
of EXP to queue mappings being done in the MPLS + RSVP-TE case, which may or
may not result in a performace difference.

Second, read mpls-linux/utils/README for info about binding FECs to LSPs.
Or take a look at my example on http://mpls-linux.sf.net/
