Php 三种加速器的性能对照
Php 三种加速器的性能对比
硬件环境:
服务器:DL180G6 (16 Intel(R) Xeon(R)CPU E5620 @2.40GHz) 16G内存
压力机:DL180G6 (16 Intel(R) Xeon(R) CPU E5620 @ 2.40GHz) 16G内存
软件环境:
nginx1.2.5php5.4.9 最大600php-fpm
网络环境:千兆
测试场景:
场景一:(无任何扩展):
场景二:(开启APC 3.1.14,分配缓存512M):
场景三:(开启XCache 3.0.1,分配缓存512M):
场景四:(EAccelerator 1.0-dev ,分配缓存32M):因无法设置512,测试页生成的缓存为1.15m所以影响不大。
以上四种场景,并发相同的用户数20 (是最佳用户数),访问同一URL(http://playback.i.ifeng.com/hehe.pi?vt=5),每个场景运行5分钟,对比三种Php缓存在同等压力下的性能情况。

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
