Are you using APIC irqs?

Hmm! I guess the routing table size has a slight difference on
performance there.
I assume you have CONFIG_IP_ROUTE_LARGE_TABLES enabled.
If not, try with that turned on. If you had it on or enabling
it makes little difference, it is time to play with FZ_MAX_DIVISOR
and fn_hash().
All of your BGP routes have the same prefix right? Yes, with ~181000
routes which you have fib zone hash in current state will fall to
pieces I am afraid. (even with perfect hash, chain length would be
on the order of ~180 entries :-((( )
I'm not sure if this is a "good" profile or not... I can try with
oprofile or something instead if that gives more useful results.
It is good, thanks.
Alexey, I will try to make something...
