Phoronix: Upcoming Linux Benchmarks For August 2012
In August on Phoronix will be more benchmarks of Mesa 8.1, a Linux review of the Apple MacBook Pro with Retina Display, OS X Mountain Lion vs. Linux benchmarks, and other interesting articles (e.g. Valve's latest Linux activities) and performance benchmark results...

I HIGHLY support the web server testing benchmarks. I get the feeling that Apache has been outclassed by a few others by now but no one really realizes it because server benchmarks are fairly rare. I've seen some, but it would be great to see a truly scientific version.
