搬瓦工 洛杉矶CN2/KVM/VPS主机/512MB内存 简单评测

搬瓦工在8月推出洛杉矶C3节点的时候简单分享过一次,当时还只有一个套餐方案,现在已经正式运营了,当然以前购买的其他节点的基于KVM架构的VPS主机可以通过管理面板中切换到新的机房,不过那些已经指明了不可以更换机房的方案同样不可以切换。估计是由于成本的增加,切到洛杉矶C3机房,流量要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。

7、小结

IO性能整体上还是不错的,对于用来搭建一个小站来说绰绰有余了,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,具体的KVM常规方案可以参见:搬瓦工KVM便宜货
