Could you explain what a "regular" Hello Rails page is? :-)

That's a lot of hardware.

Those numbers sound a low to me, actually. I'd expect at least 40 page
of session creation + rhtml render (no other DB activity) per core,
which
would be around 320/second.

Is the DB on the same box? Was the test running on the same box?

I'd recommend you run 8 nginx (1 per core), and 32 mongrels (4 per
core).

Also, 10,000 concurrent requests seems a bit high, but shouldn't
really
affect aggregate perforance.
