Actual server performance demonstrations, LIVE from Intel labs.
You will need to register to see it, but when you get in, its something new. I've been to the lab, I have seen the systems first hand. Heck, I even supplied a system or two to the cause. This is pretty cool.
If you have any questions about this and would like answers from the people who made this happen, let me know. I work with them.
