Interesting! It is a good start point, I think.
I have some questions and comments.
* What NIC did you use for your benchmark?
* How many clock interrupts per second (hz value)?
* Did you measure TCP/IP performance?
I suppose this may hit TCP/IP performance, because ACK
transmission delay may not be negrectible under low clock
I suppose, for the first step, making generic polling
interrupt handler, without NIC driver changes, is better.
Do you consider sporadic server or some kind of similar
handler on NetBSD?
