请注意Rails2.3自带的memcache-client有性能问题

2.3.2.1就是用gem install的2.3.2

我测下来性能差距在10%, 2.3慢，主要在render部分，如果没有render view，性能持平
有空大家也测测看

补充一下，如果view比较复杂，有loop render partial的n>10，差距稍稍增加，也不超过15%

昨天刚升到2.3.2，xp 下面，跑ruby1.8.6，感觉开发的环境下速度快多了，2.2.2的时候一刷页面，机器就慢下来，现在好多了。。不知道生产环境如何

好像看到一个测试数据, python 应该是动态语言里面速度最快的,
robbin当初为何没有选择python 呢?

A Note About Template Loading

After some extensive work by several authors (here’s the Lighthouse ticket), Rails 2.3 includes the ability to enable or disable cached templates for any particular environment. Cached templates give you a speed boost because they don’t check for a new template file when they’re rendered – but they also mean that you can’t replace a template “on the fly” without restarting the server.

In most cases, you’ll want template caching to be turned on in production, which you can do by making a setting in your production.rb file:


config.action_view.cache_template_loading = true

This line will be generated for you by default in a new Rails 2.3 application. But please note: if you’ve upgraded from an older version of Rails, you won’t have this setting in your production.rb and template caching will be off by default. Unless you really need the ability to update templates in production without restarting the server, you should be sure to add this setting when you upgrade.

ror好处是开发快，但部署好象就不那容易了

这个比apache+PHP基本上不会存在这个问题

这个是许多网站前台均用php的原因
