On a SPARC T3-1:

1) Output route lookup: ~2800 cycles
2) Input route lookups: ~3000 cycles (rpfilter=0)
                        ~4300 cycles (rpfilter=1)

Out of curiosity I got rid of the local table and made all routes
go into the main table and those numbers above become:

1) Output route lookup: ~2500 cycles
2) Input route lookups: ~2800 cycles (rpfilter=0)
                        ~4100 cycles (rpfilter=1)

And with the neighbour patches I posted tonight these numbers are:

1) Output route lookup: ~2150 cycles
2) Input route lookups: ~2600 cycles (rpfilter=0)
                        ~3700 cycles (rpfilter=1)
