This topic may be going on in multiple threads, so apologies if I
am missing something.  In this thread I notice a reply with the
benchmark:

     Here's one benchmark, showing UDP packet/second generation
     rate from userland on a dual xeon machine under various
     target loads:

     Desired Optimal 5.x-UP  5.x-SMP 4.x-UP  4.x-SMP
      50000   50000   50000   50000   50000   50000
      75000   75000   75001   75001   75001   75001
     100000  100000  100000  100000  100000  100000
     125000  125000  125000  125000  125000  125000
     150000  150000  150015  150014  150015  150015
     175000  175000  175008  175008  175008  169097
     200000  200000  200000  179621  181445  169451
     225000  225000  225022  179729  181367  169831
     250000  250000  242742  179979  181138  169212
     275000  275000  242102  180171  181134  169283
     300000  300000  242213  179157  181098  169355

That does show results for both single-processor (5.x-UP 4.x-UP)
and multi- processor (5.x-SMP, 4.x-SMP) benchmarks.  It may be
that he ignored the table as soon as he read "dual Xeon".

But when he asked for a "pointer or reference", I was expecting
to see a URL which pointed to some additional benchmarks.  I did
not notice any URL's in any of your replies in this thread.  Did
you think that you had included a URL in some reply, or were you
referring to the above benchmark?  Or did I just miss the reply
which included that URL?

Mind you, the above benchmark is very encouraging, so I am not
complaining about it.  I am only wondering if there were additional
benchmarks written up.  Well, I am also wondering what the reason
is for both a "desired" and "optimal" column in the above.  When
would "desired" ever be different than "optimal"?   :-)
