Nginx http proxy cache to mirror of Rubygems.org
# 在本地服务器建立 rubygems.org 的镜像缓存，以提高 gem 的安装速度
# 此配置设置缓存过期为1天，也就是说，新上的 gem 无法马上安装
# 做这个起什么作用？
# rubygems 的很多资源文件是存放到 Amazon S3 上面的，由于 GFW 对某些 S3 服务器又连接重置或丢包，导致 gem 安装异常缓慢或有时候根本无法连接安装。
# 而通过这种跳板的方式可以很好的解决这个问题，当然前提是 Nginx反向代理 服务器需要在国外

Unicorn memory usage improvement with Ruby 2.0.0

Unicorn memory usage improvement with Ruby 2.0.0

Here's a preliminary experiment to see how much memory is saved with the new copy-on-write friendly (bitmap marking) GC.

Calculated by memstats.rb https://gist.github.com/kenn/5105061 on Debian x86_64.

Master process:
