最近在群里看到有朋友在聊莱卡云，说实话，我之前对这家了解也不多。查了一下，发现是家正规公司（广东莱卡信息技术有限公司）运营的，有正经备案，不是那种随时可能跑路的小作坊，感觉靠谱了不少。他们家主营VPS和虚拟主机业务，今天我手上正好拿到一台机器，就来给大家实际测评一下，看看这家的香港VPS到底值不值得上车。

VPS套餐
他家的香港套餐选择还挺丰富的，从入门级的1核1G到高配的16核32G都有，丰俭由人。主打一个免备案，配置可以弹性升级或降级，还带RAID10数据保护，对建站用户来说是个不错的保障。官方标称平均延迟30+ms，听起来很香，我们后面会实际测一下。

测评数据
废话不多说，我这次拿到手的是4核8G的套餐，咱们直接上干货，是骡子是马，拉出来遛遛就知道了。
先看下基本配置，CPU是E5-2660 V2，虽然是老将了，但性能应付绝大多数建站和应用场景还是够用的。KVM虚拟化，这已经是行业标配了，没什么好说的。
用柠檬脚本跑了一下，CPU和内存的性能表现中规中矩，符合这个价位的预期。比较明显的是IO被限制了，不过这在共享VPS里是常规操作，可以理解，主要是为了防止某个用户滥用导致整台母鸡性能雪崩。
不死心，又用FIO单独测了下IO，果然是限制了。其实对于我们正经建站的用户来说，IO限速反而是件好事，能保证我们的网站不会被邻居的IO怪兽拖垮。
跑分成绩大家看个乐就行，因为性能有限制，分数自然不会太高。但有个亮点，我试了下流媒体解锁，发现奈飞这些都能看，这对有看片需求的朋友来说，算是个意外之喜了。
网络速度是重点考察对象。我特地选在晚高峰，不开BBR的情况下直接跑速，可以看到带宽基本都能跑满。这个表现相当稳了，说明网络质量还是靠得住的。
再看看全国Ping延迟，一片绿油油的，看着就舒服。国内访问延迟很低，表现相当优秀，做站体验会很好。
最后，也是最关键的路由信息。这里有个挺有意思的发现：商家在产品页宣传的是CN2线路，但我实际拉路由测试后发现，无论是电信、联通还是移动，三网回程都齐刷刷地走了CMI。CMI线路对移动用户极其友好，整体速度也不赖，但终究不是CN2。这一点大家在下单前心里一定要有数，别被宣传误导了。下面是详细的路由跟踪数据，大家可以自己看。
