搬瓦工在双十一期间推出的一款特价KVM VPS服务器方案货源已经补充过几次了，目前均还有货源，本站在第一时间入手了一台，基本上处于压箱子的状态，依然是默认的洛杉矶QN（DC3）数据中心。在这个折腾比较多的时间段，简单看看其表现吧。
一、配置方案：
- 核心：2核CPU
- 内存：2GB
- 硬盘：40GB
- 流量：1TB
- 端口：1Gbps
- 架构：KVM
- 优惠码：BWH26FXH3HIQ 可以节约一点点；
- 价格：$29.88/年
- 传送：购买链接
注：在执行wget请求的时候出现wget: command not found这样的一个提示，其实是系统WEGT 没有安装。安装的方式非常简单，只需要以下的一条命令就行啦！
输入命令：yum -y install wget 就会自动安装WGET，这样问题就解决了！

六、小结
目前宿主服务器几乎处于饱和状态，跑分花了不少的时间，整体上来看只能算是入门的水平，不过用于搭建一个小站或者网络加速服务还是可以的，稳定性以及网络质量方面估计要等段时间，等折腾的少了之后也许会好一些。现在无法切换的洛杉矶C3（DC8）数据中心，洛杉矶QN（DC3）默认购买，追求稳定一些的用户可以切换到其他节点，比如洛杉矶MC（非优化线路），晚点本站切换到MC节点看看其性能如何吧。
