hostus -KVM 2G内存 2核 洛杉矶vps主机简单评测

在香港vps主机便宜货盛行的时候，hostus早早上架香港节点让其火了一把，现在hostus已经渐渐的淡出了部分伙伴们的眼中。近期hostus上架了新的一批母鸡，开的小鸡采用KVM架构，数据中心在洛杉矶、华盛顿两个节点，在定价方面还是非常不错的，即使不使用任何优惠码，1G内存套餐月付7.95刀，还是具有一定的性价比。另外流量方面也还给的比较充足，最低512M内存套餐流量750G，端口为1000Mbps。在一上线的时候小七自己就入手购买了最低配置512M内存套餐，也对其进行了简单的测试(hostus新KVM架构 512M内存 洛杉矶节点简单测试)。今天申请到一款2G内存的小鸡，主要还是看看大内存的小鸡跑分会是怎么样的一个状态呢？嘿嘿！

优惠码：KVMRELAUNCH30   老用户专用，首次折扣30%优惠，没什么实际意义。以下方案为折扣前价格，另外KVM架构，支持安装windows系统，建议1G或以上内存安装使用。官方提供的win系统需要2G内存以上的小鸡！

优惠方案

测试环境与配置：centos系统，官方原版；配置2核CPU  2G内存 ；洛杉矶节点

1、基本硬件配置

2G内存，默认1G swap，还算是不错啦！另外KVM给了2核，CPU也是当前流行的主流配置！

2、网络测试

[root@7vps ~]# wget cachefly.cachefly.net/100mb.test

国外常规测试下载速度达到97M/s的速度，的确是G口，下载国内的360也能达到8M/s，也是不错的啦！

3、硬盘IO性能

[root@7vps ~]# dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
4096+0 records in
4096+0 records out
268435456 bytes (268 MB) copied, 3.88487 s, 69.1 MB/s
[root@7vps ~]# dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
4096+0 records in
4096+0 records out
268435456 bytes (268 MB) copied, 2.91755 s, 92.0 MB/s

硬盘性能还是不错的，对于流量几千IP的来说够用了，当然如果您的程序非常占IO也是么办法的。国内的阿里云、腾讯云。西数等硬盘IO一般，特别是华夏小云硬盘IO性能更低，对于小站足够使用，当然流量上万IP建议直接上高配置的服务器啦！

4、站长网ping测速

性能还是非常不错的，2核2G内存套餐跑分超过2000分是相当不错的啦！对于KVM架构适合建站的朋友，当然玩个人上网服务也是不错的！对于ping的测试小七也是在高峰期ping还能平均在200左右还是不错的，hostus洛杉矶线路目前走的是亚洲优化段，经香港链接大陆，当然与所谓的电信直连之类的还是有点点差别！国外线路在高峰期不管那条或多或少延迟较高，部分丢包率也高，这些都是无法避免的！
