AlphaRacks KVM 主机跑分评测

AlphaRacks 家的主机相当便宜,之前就买过他们家的 OpenVZ 主机,$10 一年的样子,但是速度真的很慢,搭梯子也就只有每秒几百 KB 的峰值,可见其超售确实严重(100% 不推荐购买)。向客服申请退款后,他们只是将金额退还到了我的余额里,最近他们给我发促销邮件表示,提供 $15 一年的 KVM 主机,想到反正那笔钱也取不出来,于是就买了台试试。

价格:15 刀 1 年
虚拟类型:KVM
机房位置:洛杉矶
其他信息:已开启 BBR,未购买其 1GbPS 的宽带加速包

结论

可以看到 KVM 机型的网速还是相当不错的,$15 的综合性价比毫无疑问属于中上水平,值得购买。但是我还是要忍不住再啰嗦一句,不要购买他们家的 OpenVZ 机型,超售严重,网速极慢。
