About PHP Performance optimization

Shown as 100 concurrent, request 1000 times Destination Address

To test

The most important two parameters:requests per second : Receive requests per second, where 101 requests per second

　　　　　　　　　Time perrequest: How long a request takes, here is 9 milliseconds

The larger the first parameter, the better, the smaller the second parameter, the better.

Optimization method of language-level performance optimization 1

PHP Code Execution Flow:

PHP code through the Zend Engine line by scan, become the Zend engine can understand the syntax, transcoding parsing into opcodes, after execution output

If you use the built-in function more quickly, the time will be much faster in scanning and understanding, opcodes will be less, execution will be fast.
