vps跑分记-综合性能测试

2013年4月21日 发表评论 阅读评论

最近迷上VPS,购买必考虑性能,如何了解性能,可以参考一下这篇VPS跑分记。跑分差的可以考虑在退款期限内,退款。

问:什么是跑分?

答:跑分是一种用某些以分数体现性能的测试软件测试机器性能的行为。

问:用什么软件对vps进行跑分(即用什么软件对vps进行性能测试)?

答:UnixBench是一款常用的vps性能测试程序,简称UB。Unixbench的主要测试项目有:系统调用、读写、进程、图形化测试、2D、3D、管道、运算、C库等系统基准性能提供测试数据。

如何对vps进行跑分

1.安装UnixBench

登陆VPS后运行以下命令

wget http://www.CTOHome.com/linux-vps-pack/unixbench.sh;sh ./unixbench.sh;

一般VPS运行以上命令都会自己下载、安装、运行UnixBench,直接等分数出来就好。如果跟本人一样出现

Run: “make all” failed; aborting

并且有以下提示,则说明VPS没有安装好 GCC 模块。

make: gcc: Command not found

DEBIAN运行apt-get install gcc ?#安装GCC

CentOS运行yum install gcc ? ? ??#安装GCC

安装完成后GCC后从新执行上面第一条红色命令,如出现以#号围成的?Unix Bench 字样那就说明跑分行动已经开始,请耐心等待分数,一般需要等10几分钟。

跑分结束出现如下结果:

跑分结束鸟博主的VPS只得鸟 1201.6 分,表现较为一般;第二个是并行测试分数2031.2,其实意义我也不大懂,知道的麻烦科普一下。

除了用UnixBench进行综合性能测试之外,我们也能用以下2个小命令进行单项性能测试哦

1.进行硬盘性能测试的命令

dd if=/dev/zero of=test bs=64k count=4k oflag=dsync

结果大于10MB/S为一般,大于50MB/S为优秀

2.进行网速测试的命令

wget 某大型文件,如:

wget?http://sjc.hawkhost.com/100mb.zip

PS.这个数据与下载目标与VPS所在机房之间的网络连接路线有关,与同服务器其他VPS实时多网络的占用达也有关。由于影响因素过多,不确定性大,所以网速测试参考意义较小。
