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。
