Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

"Facebook has announced the release of its "HipHop" tool under the PHP license. "HipHop for PHP isn't technically a compiler itself. Rather it is a source code transformer. HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it. HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features - such as eval() - in exchange for improved performance. HipHop includes a code transformer, a reimplementation of PHP's runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations." These optimizations are said to double the speed of PHP code."
