For the record, what I was saying was that a decent machine (e.g. 2.4 PIV) should be able to push 200,000 packets per second with decent NICs (em, or fxp) and with a median packet size (see www.caida.org) of about 540 bytes, that works out to ~ 100Mb/s. No you didn't, you said that 200Kpps would show almost no cpu usage, which is utterly ridiculous.
