测试设备：嵌入式Linux设备测试场景：办公区测试方法：连接远程服务器，测试网速

3. perf3

测试命令：

iperf3 -c xxx.xxx.xxx.xxx -p 5002 -i 1 -t 60000 -P 10

xxx.xxx.xxx.xxx，服务器IP
-i，指定打印间隔
-t，指定测试时间，单位s
-P，指定测试并行数，不添加默认为1个线程
-p，指定测试端口
-c，指定测试模式，-c客户端模式，-s服务端模式

测试结果：

办公室网速大概 1.6Mbps左右。

4. curl

生成测试大文件：

dd if=/dev/urandom of=file1 bs=1M count=20

启动测试：

curl -u "user:name" -T file1 ftp://xxx.xxx.xxx.xxx/90400535/

测试结果：

/usrdata/QuecOpen # curl -u "user:name" -T file1 ftp://118.178.106.177/90400535/% Total % Received % Xferd Average Speed Time TimeTime CurrentDload Upload Total Spent Left Speed100 20.0M 00 100 20.0M0 190k 0:01:47 0:01:47 --:--:-- 208k

使用curl实际传输文件平均速度为208kB/s

5. 总结

总结，使用curl、iperf测试结果一致，iperf：1.6Mbps，curl：208KB/s，等价208*8=1.6Mbps

6. 其它网络测速方法：

6.1 wget

测试下行速度。
