使用重定向VS重写规则的速度影响 [英] Speed implications of using Redirect vs RewriteRule

问题描述

我很好奇，想知道是否有速度的规则集之间的区别，并在在Apache中的.htaccess规则重定向。

I'm curious to know if there is any difference in speed between RewriteRules and Redirect within a .htaccess rule on Apache.

在我看来，规则集往往是复杂的正则表达式EX pressions我假设有开销（即使是小得令人难以置信）相比，重定向，这将是简单的字符串匹配（？）

To my mind, RewriteRules can often be complex regex expressions which I assume have overhead (even if it's incredibly small) compared to Redirect that would be simple string matching(?)

所以，如果我有：

RewriteRule ^mytestpage\.html$ http://www.google.com [R=301, QSA]

VS

Redirect 301 /mytestpage\.html http://www.google.com/

我可能永远不会注意到差别，但如果我有1000独特的重定向？或10,000？难道是adventagous使用一个比其他？

I'm probably never going to notice a difference, but what if I had 1000 unique redirects? or 10,000? Would it be adventagous to use one over the other?

推荐答案

使用或者是可以忽略不计，你不会发现有不同的速度产生影响。话虽这么说，你应该使用合适的工具来完成工作。

The speed implications of using either is negligible and you won't notice a difference. That being said, you should use the right tool for the job.

做一个简单的重定向，你应该使用使用mod_rewrite的重定向代替。这个例子是什么重定向应该照顾。当你需要开始做更复杂的事情，你可以考虑使用mod_rewrite。

Doing a simple redirect, you should use a Redirect instead of using Mod_Rewrite. That example is something a Redirect should take care of. When you need to start doing more complex things you can think about using Mod_Rewrite.

即使1000或10,000重定向你不是真的要注意到一个很大的区别。但是它会使用更多的内存。大概几MB的，如果这一点。

Even with 1000 or 10,000 redirects you're not really going to notice a big difference. However it will use more RAM. Probably a few MB's if that.

因此​​，要回答你的问题，它确实不会产生实质性的影响，但使用正确的工具来完成工作。

So to answer your question, it really wont have a real impact but use the right tool for the job.

这应该有所帮助。

当不使用mod_rewrite
