Send it over, I'd be interested in how you're conducting these tests.
I'm not trying to accuse you of lying or slandering your competitors
or anything, but well, those numbers sound a bit funny.

Not a meaningful comparison; vastly different architectures and
purposes. I'd be more interested in seeing empirical data comparing
the FastIron 4802 to... say... a Catalyst 2948G-L3 or Extreme Summit
48i. Maybe a Cat6k/MSFC2 as well, seeing as the pricing is roughly
comparable in the used hardware market, even if the density is not.

Sounds reminiscent of the dot.gone wastefulness that killed many
companies. :-)
