今天偶然看到这个东西

http://www.rubyenterpriseedition.com/

是 Ruby 的一个分支。

之前只是了解过 J2EE，没想到 Ruby 也有企业版的。不过貌似不像 J2EE 关心的是解决复杂的业务逻辑，而 RubyEE 是提高 Ruby 性能

Ruby Enterprise Edition is a branch of Ruby, which includes:

• An enhanced garbage collector. This allows one to reduce memory usage of Ruby on Rails applications (or any Ruby application that takes advantage of the feature) by 33% on average.
• An improved memory allocator. This increases Ruby's performance drastically.
• Various developer tools for debugging memory usage and garbage collector behavior.

网上资料比较少，有用过的朋友能谈谈吗？
