VPS下的Rails应用服务器选择
在我多次重装系统,重装环境后,终于发现,之前写的文章http://mangege.iteye.com/blog/992571提到的你推测问题是由于应用服务器引起的.在VPS下,thin的反应速度太慢了,打开一个页面要2~3秒甚至更久,Passenger的速度很快,一点就开.看样子Passenger有针对VPS优化过
我只是测试的比较一下thin和Passenger,其它的应用服务器就不比较了,Passenger已经满足了我的需求.
VPS 环境:UBUNTU 10.04,Ruby 1.9.2(不一定要REE)

受网络影响,速度有可能不准确.从数据可以看出,性能大致差不多.但如果直接用浏览器打开,个人能够明显感觉出Passenger要快.所以在VPS不要为了省事,而选择安装thin
