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?
With this free program you can perform 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 nice small footprint.
