A great talk recently given by Rasmus Lerdorf at the "Hacker Dojo' in San Francisco. Lots of goods inside, particularly around the usage of Hiphop PHP.
One of the first benchmarks of Hiphop PHP. Where it is said to be 200x times faster than PHP as an Apache module for massive Singleton or Static calls.
A first benchmark of the main PHP compilers. Where HipHop PHP seems to perform well, but not at a tremendous level as expected. The benchmarked PHP code is only non-object code.
