购买了Onexenvps。想看看这个VPS的性能如何。使用的版本是Unixbench 5.1.2。安装和测试结果记录如下。
首先VPS一般不运行X11程序。为了避免编译错误，要修改解压后的Makefile，并注视掉一下两行：
# Comment the line out to disable these tests. GRAPHIC_TESTS = defined # Set "GL_LIBS" to the libraries needed to link a GL program. GL_LIBS = -lGL -lXext -lX11
接下来运行Make，然后就是在当前目录下输入 ./Run 进行测试。测试时前面会有提示sh: 3dinfo: command not found，这是因为没有编译图形测试模块的原因，可以忽略。经过比较漫长的等待，这个内存128MB，10G硬盘的VPS成绩如下：
