apache的mod_disk_cache模块测试-小Y

开启mod_cache和mod_disk_cache模块

CacheEnable disk /

CacheRoot “/tmp/apache/disk_cache”

CacheMaxFileSize 10000000

CacheMinFileSize 1

CacheDirLevels 3

CacheDirLength 3

</IfModule>

保存，重启即可开启http磁盘缓冲

但只对html进行缓冲，有网友发现php文件由于session模块影响不能缓存，可进行如下修改

增加：

LoadModule headers_module modules/mod_disk_cache.so

然后在httpd.conf中(主配置文件、<VirtualHost>、<Directory>、.htaccess文件等配置段)添加以下配置项即可：

Header unset Expires

Header unset Cache-Control

Header unset Pragma

Header set Cache-Control “public, max-age=259200″

参考原文关于php不缓存的说明：http://blog.csdn.net/cschmin/article/details/5972239

保存重启apache

测试成功，这样就可以让php页面经过缓存后达到静态页面的访问速度，简直不要太吊

前后吞吐量比较：

前

Requests per second: 682.45 [#/sec] (mean)

Time per request: 146.531 [ms] (mean)

Time per request: 1.465 [ms] (mean, across all concurrent requests)

Transfer rate: 33750.28 [Kbytes/sec] received

后

Requests per second: 4501.16 [#/sec] (mean)

Time per request: 22.216 [ms] (mean)

Time per request: 0.222 [ms] (mean, across all concurrent requests)

Transfer rate: 225611.81 [Kbytes/sec] received

这样子是不是比dedecms的页面静态化还要叼几百倍？
