VPS性能综合测试（6）：UnixBench跑分工具测试

测试时间可能会比较长，请耐心等待。最后UnixBench会详细列出各个测试项目的得分情况，以及VPS性能的综合跑分结果

UinxBench 的使用

使用方法如下：

Run [ -q | -v ] [-i <n> ] [-c <n> [-c <n> ...]] [test ...]

The option flags are:

  -q            Run in quiet mode.
  -v            Run in verbose mode.
  -i <count>    Run <count> iterations for each test -- slower tests
                use <count> / 3, but at least 1.  Defaults to 10 (3 for
                slow tests).
  -c <n>        Run <n> copies of each test in parallel.

测试示例

在虚拟机上的测试

虚拟机配置如下：

• CPU: 1
• RAM: 2GB
• SIZE: 20GB

测试结果如下：
