the next paragraph reads:

In additional testing using VolanoMark's network scalability test, a 12-way
AS/400e Model 840-2418 using a single Gigabit Ethernet connection surpassed
all previous results. The AS/400e server with 8GB of memory was able to
process 39,529 messages per second at 9,000 connections -- more than eight
times the results of the Sun E6500 22-way server.


So, 108,153 messages/second was more than FOUR times Sun's E6500 22-way
server
and   39,529 messages/second was more than EIGHT times Sun's E6500 22-way
server.

Clearly someone got some numbers screwed up here casting doubt on the whole
thing. Also, the first benchmark used 200 connections, the next 9000
connections.
Something is not right here. Don't just be hornswoggled by marketing hype.
Think
a bit yourself...

Actually, the two paragraphs are not strictly speaking contradictory. Assume
that
Sun's server could only handle 10 messages/seconds, then both paragraphs
would
be true, since 108,153 is MORE than 4*10 and 39,529 is MORE than 8*10.  :-)
