Hi George,
I have posted my results in of the mails, but here
they are again:

Ingress: 3.665 milli seconds
Egress: 0.035 milliseconds
core:    0.018 milliseconds
 
IP: 0.023 milliseconds.

For my measurements I have attached a sniffer at both
incomming and outgoing interface (same sniffer for
both so no clocking issue). I did the same thing for
boths LSR and LERs. Question of number of LSRs should
not affect the results, considering my measuring
technique.
Jing said He is also getting similar results, I am not
sure how he has done his measurement.

Thanks,
Nitin
