prometeus.net家192M内存VZ测评,15欧/年

买了一个prometeus的低端VPS,花了15欧元相当于人民币121元吧。整体来说速度确实很一般,相当于美国最东部的速度差不多甚至可能还慢点儿,好处就是不管是电信还是联通或者移动都不抽风,这个是我观察了好几个月的结果。prometeus在LEB上目前排名第一,可靠性是非常好的,有自己的数据中心的,而且是注册公司,运营经验有十多年….

VPS的基本配置信息:192M内存,192Mswap(二代),8G硬盘,1个IPV4,2个IPV6,512G流量每个月,SolusVM面板,linux系统,基于openvz (unmanaged)。购买地址 https://www.prometeus.net/billing/cart.php?gid=12 PS:他们家128内存和192内存以及所有低端VPS都经常没货,特别是128M和192M内存的基本上不上货,我是无聊就去看看刚好遇上别人掉下来的,我特地查看了一下这个IP之前是做过网站的。

下面的简单测试不是同一天做的,可能服务器负载不同也会造成测评数据之间的差异。之前写过这家的KVM测评,那确实是一分钱一分货。参看

Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz | 频率:1200.000 | 二级缓存:15360 KB | Bogomips:4000.06
关于CPU需要说明一下的是他们把CPU限频率了,保障频率是1200MHZ,但是可以冲到2000MHZ

在北京时间下午七点二十的时候做了一下DD测试,确实非常的差强人意,不过只要稳定建小站还是不成问题的!
