Interesting, but let's be honest for a second, in 99.99% of the cases, a classic Apache+mod_php will be well suited. You could count on your hands the number of sites that require a setup that needs to handle 12,000req/sec and more.
If you need to speed things up, reduce the memory footprint, i'd recommend using APC or eAccelerator, and put something like Varnish or Squid in front. As well as ditch stuff like WP or Drupal, might be nice and easy to use, but the code behind it is just a disaster if you want something fast and optimized.
Use extensions like XHProf or Xdebug to profile your code, and find the bottlenecks and memory eating functions.
Stop blaming Apache/PHP, they both have defaults, but in most of the case, the default is in the code.
