Thats what i am hoping - and theory points to it. Numbers, numbers
please ;->
I agree that multigigahertz box will beat my HIFN card, 
but I doubt it can beat 1gghz VIA.
The VIA is an interesting one; but it would still be interesting to see 
comparisons.
Actually I should say a good comparison will be with a dual opteron
= 2Ghz which i have no doubt will smoke a xeon - all in s/ware.
And what about random numbers, async crypto, TPM?
They all requires some kind of generalization.
Similar deferal approach should do it.
If you are brave, you should probably experiment as well with
non-crypto stuff to defer things like gettimeofday computes.
(i.e ask the hardware for time, defer response and then call netif_rx
with a tag saying time has been computed).
