performance metrics

[Frans Kaashoek]

>From the software plugins paper: "Compared to a monolithic best-effort
kernel, our implementation requires an avarage increase in packet
processing overhead of only 8%, or 500 cycles/2.1msec per packet when
running on a P6/233."  (3 gates with empty plugins)

Other numbers:

Unmodified NetBSD1.2.1  36800 (pkts/s)
NetBSD with plugin arch 34100
NetBSD with ALTQ&DDR    28600
NetBSD with plugin DRR  28729

The packet size in these experiments is 8Kbyte (UDP/IPv6). Network
interface: ATM.
