New patch at the end this time, getting rid of rt->rt_dst :-) Most recent performance numbers:
1) Output route lookup: ~2150 cycles
2) Input route lookups: ~2600 cycles (rpfilter=0)
~3700 cycles (rpfilter=1)
How things stand now:
1) Output route lookup: ~1600 cycles
2) Input route lookups: ~2200 cycles (rpfilter=0)
~3100 cycles (rpfilter=1)
