Zend Optimizer+ will land in PHP 5.5
Zend Optimizer+ is to be integrated into the currently-in-development PHP 5.5. The announcement was made by Zeev Suraski, CTO and co-founder of Zend Technologies. The opcode cache and code optimiser was recently open sourced; previously it was only available as part of the proprietary Zend Server. It improves the performance of the interpreter by optimising the bytecode generated from PHP source files. It also stores precompiled bytecode in shared memory instead of reloading and recompiling source code from the hard disk when needed.
