Close collaboration between Intel and the PHP community enables new hardware features that improve processing efficiency, increase execution speed, and optimize core software of interpreted languages — significantly boosting PHP 7 performance on Intel® Xeon® processors
Choosing the right combination of hardware and software is one of the simplest and most effective ways to improve performance for PHP-based applications. To this end, Intel has shared knowledge, insight, and hints with the PHP community to help boost PHP performance and optimize this popular language on Intel® Xeon® processors.
In addition, the software performance of PHP 7 sees a boost with each new generation of Intel® Architecture (IA), which introduces features that increase hardware execution efficiency. At the source level, Intel has also worked extensively to “tune” processors. This increases execution efficiency and performance even further — performance that is particularly important for PHP and other interpreted languages that have a large footprint.
These collaborative efforts have enabled two key advances for PHP 7 over the previous version (PHP 5): a much smaller memory footprint, and a dramatic 2x performance gain for real-world applications on Intel Xeon processors.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
