BTW, NetBSD with the recent flow cache mods can handle at least 150,000 packets per second. We haven't seen what the actual upper limit is, but that number doesn't seem to be eating a lot of CPU.
Interesting. Have you done any scalability testing? Per-flow state has been shown to scale poorly in Internet backbones.
That was with one flow. The idea of "there basically aren't flows" is not obvious on first approach to these problems, wouldn't you say, Tony :-)?
Not obvious to some, but we sat and watched a significant router vendor make that mistake (despite good advice to the contrary) anyhow. I'd hate to see someone else repeat that mistake. Tony
