昨天帮实验室买了个Linode 360的VPS，梦寐以求哇，迫不及待的去折腾。选在了加州的fremont机房，北京网通的ping值大概在210ms左右，很极品的速度了，ssh上去交互只有一点点地小卡。装的CentOS 5.5，然后配了几个shell账号，通过he.net提供的tunnel broker增加了IPv6的支持，最后装了个启用passenger-ruby模块支持的nginx。明天继续折腾。
下班前顺便跑了一下Unix Bench 5.1.2，硬件配置上是一颗Intel Xeon L5520 2.27GHz四核的CPU， 8M Cache, Xen虚拟化，360M RAM，16GB Hard Drive。结果如下。
