PHP7 - For Its Best Performance
The document discusses PHP7 and how to optimize it for best performance. It notes that PHP7 is up to twice as fast as PHP5.6 and uses significantly less memory. It then provides several recommendations for further optimizing PHP7 performance, such as using Unix domain sockets, opcache file caching, profile guided optimization, and huge pages. Real-world benchmarks from companies show PHP7 provides 15-40% better performance.
