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。

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

Best PHP Performance Optimization TechniquesBest PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
