JDs Auto SpeedTester

这个免费软件能够在后台做常规的网络速度测试，使你能够看到所有的关于网络的数据，包括PING时间，上传下载速度，丢包率，抖动情况等。它将产生CSV记录文件，并能用图形表示出来它记录所有数据，使您一眼就能看到你的速度，可以选择小时/天/周/月等。

Does your Internet services provider supply you with the service speeds that were advertised? Does it do this 24 hours a day 7 days a week? (as you can see from the pic above mine does not) With this free program you can do regular internet speed tests in the background. It logs all your data and enables you to see at a glance what your speeds are doing over the course of the hour/day/week/month etc. It will test your download & upload speeds your ping times, packet loss and jitter. It will generate a CSV log file for all this data and also present you with a graphical representation. you can also create screen shots of the graph & the manual results window. The memory usage i have managed to get down to approx < 2MB whilst in "sleep" mode (in tray) so a very small footprint.
