很多时候，我们购买了VPS第一件事就是第一时间跑一下配置，测一下网络、IO、内存、磁盘、这些看一下有没有什么问题。所以如果是基本操作，秋水的bench.sh已经够用了，但是有时候我们需要更加详细的测试，所以接下来这个脚本非常适合我们使用。
一、安装
wget git.io/bench.sh
详细使用参数：
Arguments:
-info - Check basic system information
-io - Run I/O test with or w/ cache
-cdn - Check download speed from CDN
-northamercia - Download speed from North America
-europe - Download speed from Europe
-asia - Download speed from asia
-a - Test and check all above things at once
-b - System info, CDN speedtest and I/O test
-ispeed - Install speedtest-cli (python 2.4-3.4 required)
-speed - Check internet speed using speedtest-cli
-about - Check about this script
Parameters
share - upload results (default to ubuntu paste)
Available option for share:
ubuntu # upload results to ubuntu paste (default)
haste # upload results to hastebin
clbin # upload results to clbin
ptpb # upload results to ptpb
-info - Check basic system information
-io - Run I/O test with or w/ cache
-cdn - Check download speed from CDN
-northamercia - Download speed from North America
-europe - Download speed from Europe
-asia - Download speed from asia
-a - Test and check all above things at once
-b - System info, CDN speedtest and I/O test
-ispeed - Install speedtest-cli (python 2.4-3.4 required)
-speed - Check internet speed using speedtest-cli
-about - Check about this script
Parameters
share - upload results (default to ubuntu paste)
Available option for share:
ubuntu # upload results to ubuntu paste (default)
haste # upload results to hastebin
clbin # upload results to clbin
ptpb # upload results to ptpb
举个例子，我们有时候有国内小鸡，大多都是1M带宽，所以对网速测试可以跳过，使用：
wget git.io/bench.sh;bash bench.sh -info #查看系统信息
wget git.io/bench.sh;bash bench.sh -io #测试读写速度
wget git.io/bench.sh;bash bench.sh -speed #speedtest测试服务器速度
wget git.io/bench.sh;bash bench.sh -io #测试读写速度
wget git.io/bench.sh;bash bench.sh -speed #speedtest测试服务器速度
如果机器是国外的，那就没啥顾虑，直接全部跑一遍，包括各个地方的下载测试，非常全面：
wget git.io/bench.sh;bash bench.sh -a #测试所有项目
如果想分享跑分结果：
wget git.io/bench.sh;bash bench.sh -a share #测试所有项目并分享
在跑分完成后，会给出Ubuntu的在线地址，分享给别人即可。
这个脚本可以配合superbench.sh来测试国内速度，这样的测试结果我们能对整个服务器的网络情况也就非常了解。
