今天又入手一个2host.com 512MB，即C-Class级别的虚拟服务器。照列运行Unixbench 5.1.2，看看更大内存的主机性能如何。这台VPS的地址位于德克萨斯州，而我昨天从2host买的 256MB虚拟服务器的IP地址是在拉斯维加斯。不知这个公司怎么这么多存放主机架的地方。
配置如下：
Memory: 512 MB
Swap: 1 GB
Disk Space: 10 GB
Bandwidth: 9.77 TB
月付是7.99美元，而我昨天本来还有一个折扣码可以用的，没想到今天就失效了。不过如果这些资源能够真的用上，也就非常的物超所值了。
测试结果是，单核CPU测试得分500多分，同时启用四核进行并行测试，得分是800多分。通过just-ping网页从世界各地ping测试的结果看来，一般ping值都在300以下，速度也是比较理想的。估计我很可能停用256MB的VPS，而最终一直选择这个。

还没正式玩过vps，感觉很折腾
是费些时间，但是可以学习服务器配置，也有比较自由的ssh隧道操作。发现我很难回到虚拟主机了，还是VPS好。
从安装到结束，指LLMP，总共要多少时间？
我也觉得折腾啊，你这样到底是做网站呢还是玩系统？
既作网站，又玩系统。区别很大吗？
安装LLMP，目前对我来说，少则20分钟，多则1个小时，就可以让我的三个网站迁移并运行起来。
刚刚实现了数据库在不同服务器的主从同步，迁移和建站就更方便了。
我也入手一台 2HOST 512MB 的VPS，
測試出來的成績沒有你漂亮，
用 UnixBench 4.10 來測只有 230分。
用5.12测试下吧，版本不一致，肯定分数有差别的。我在这个512M的VPS运行于四核CPU的服务器，地点在Ashvill，目前觉得还行。
