宽带升级到100M之后……

前两天电信客服来电说可以把家里的宽带免费升级到100M,在外面想用家里的设备测一下实际的上下行速度。家里 7×24 小时开机的设备有一台 Mikrotik RB751G-2HnD 和一台 Buffalo LS-WXL (重刷了 Debian Wheezy 7.9),那就看看SpeedTest有没有 Linux Console 版本的吧。

果然在GitHub 上找到一个:https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py
# wget https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py
# chmod +x speedtest_cli.py
# ./speedtest_cli.py

执行下,结果还不错

再测一下 BT 下载速度,NAS 上用 transmission 下Fedora-24-Server 的镜像,速度完全只能达到3~4MB/s,dstat 一看,CPU 竟然满载……

再看一下 ROS 的 CPU Usage 竟然也达到 60~70%

看来是时候考虑新一波的设备升级计划了~~~
