Re: Route cache performance under stress

I was going to ask before, and it's probably not even possible anymore,
but have you tried on a 2.0 kernel before?  2.0 kernels probably have a
lot of other problems and don't support the new hardware, but it would be
interesting to see how it scales to many srcs/dsts before the route cache
was integrated.  It probably scales a lot more like FreeBSD does.  You'd
probably have to use eepro100s or something, though.

As a side note, note that stateless forwarding like BSD patricie tries
is no longer sufficient. Its no longer just looking up a nexthop, dec ttl,
recompute csum that we are optimizing for.
The dst cache/flowi is the way to go, so theres no going back;-> - we just
gotta make what we have work better.
