适用于互联网中的Linux系统使用，更真实的测试服务器的上行与下行实际速率。
本脚本属于暴力测试，不适宜在生产服务器上运行，可能会因资源使用过多，导致其他服务异常。
该脚本功能如下：
- 获取默认网卡名称
- 根据url列表上传临时文件
- 根据url列表下载指定文件
执行效果
默认根据当前剩余内存的70%生成临时文件，至多不超过2G大小。
[root@lolicp.com ~]# bash test.sh
当前默认网卡 ens32 上行测速将开始，等待10s...
当前默认网卡 ens32 下行测速将开始，等待10s...
当前默认网卡 ens32 物理速率为: 1000Mb/s ,实际测试流量下行速率约为: 917 Mbps/s,上行速率约为: 98 Mbps/s
当前默认网卡 ens32 物理速率为: 1000Mb/s ,实际测试流量下行格式化速率约为: 114.74 MB/s,出口流量格式化速率约为: 12.29 MB/s脚本内容
