.htaccess mod_rewrite 性能 [英] .htaccess mod_rewrite performance

问题描述

我在 SOF 上搜索了很多关于 .htaccess 和 mod_rewrite 的内容，我想知道哪个更快:

i searched a lot on SOF about .htaccess and mod_rewrite and i want to performance wise which one is faster:

RewriteRule ^([a-z0-9]+)/?$ index.php?id=$1 [NC,L]
RewriteRule ^(.*)/?$ index.php?id=$1 [NC,L]
RewriteRule ^([^/]*)/?$ index.php?id=$1 [NC,L]

因为第一个只接受字母和数字，所以执行起来会更快吗?

since the first one only accepts letters and numbers does it make it faster to execute?

推荐答案

如有疑问，请进行测试.我设置了一个运行 Ubuntu 2011.10 和 Apache2 的测试服务器，并使用 siege 负载测试应用程序执行 3 个测试.测试运行 1 分钟(或直到 5000 次失败)，有 50 个并发用户请求/index.html"

When in doubt, test it out. I setup a test server running Ubuntu 2011.10 with Apache2 and used the siege load testing app to perform 3 tests. The test ran for 1 minute (or until 5000 failures) with 50 concurrent users requesting '/index.html'

测试 #1 使用了以下重写规则配置:

Test #1 used the following rewrite rule configuration:

RewriteEngine on
RewriteRule ^([a-z0-9]+)/?$ /index.html?id=$1 [NC,L]

使用重写规则配置测试 #2:

Test #2 with a rewrite rule configuration:

RewriteEngine on
RewriteRule ^(.*)/?$ /index.html?id=$1 [NC,L]

结果:

使用以下重写规则测试 #3:

Test #3 with the following rewrite rule:

RewriteEngine on
RewriteRule ^([^/]*)/?$ /index.html?id=$1 [NC,L]
