Well, the bleeding edge is always at a premium.
But you mention a wall.  A wall doing what?
Single threaded monte-carlo?  Single postgres
query?

Almost any real-world load that will stress
a modern server box comes from multiple requests.

As for pf performance - who the hell cares?  Are
you routing between two 10GBit LANs?

If you're using that much CPU, then if you care
what OS you're using, your app is badly written,
cos you should first avoid entering the kernel
anyway as much as you can.

Personally I value a good pthread/libc much higher
than parallelism in the kernel for exactly this
reason.
