VPS推荐网在搬瓦工KVM架构VPS主机可以随意切换机房，包括新增加的CN2节点一文中提到了常规KVM架构VPS主机方案可以切换到洛杉矶CN2节点（C3机房），只是流量减少为原来的三分之一。今天简单看看搬瓦工洛杉矶CN2节点的表现情况吧，对于想要体验的提供一点点帮助吧，不过仅供参考哦。

System Benchmarks Index Score 1241.66、小结
搬瓦工洛杉矶CN2节点系列VPS主机IO性能还是非常不错的，线路回程表现还是不错的，测试本站以及电信/联通来看集中在180左右，这是基本上算是小高峰期吧，嘿嘿！对于用来搭建一个小站来说还是可以的，对于后期线路是否稳定这个没有任何一个商家可以做出保证的，嘿嘿。对于想要便宜体验的朋友，建议选择其他机房的常规方案，之后再通过后台切换数据中心现在洛杉矶CN2节点即可，就是流量少点而已，切换数据中心可以参考：搬瓦工VPS主机如何自主切换机房一文。
