Vaporware, John.  If you really have them, put together a benchmark suite.
What, it isn't easy?  It takes time?  You have to make it portable?
You have to test it on a bunch of different platforms?  You have to
gather a bunch of data? You have to let people tell you you did it wrong?
You can't handle that?

: have great integrity considering THE FACT that the only measurement results
: that were quoted were ZERO LOAD LATENCY...

Umm, John, you're the only person that interpreted the results in the way
that gives you heartburn.  Perhaps you want to show me the lat_tcp man 
page and point out where it says that this is a throughput, loading, or
anything other than a single threaded latency benchmark?  Can't find it?
How about the news posting where someone said that lat_tcp is the killer
throughput benchmark?  Or a scaling benchmark?  Can't find that either?
It kind of looks to me like you just wanted to vent.  That's cool, but
don't blame your frustration on anything but yourself.
