According to Ookla, if you want to do things like stream video, use interactive applications, and use VoIP services like Skype, you will want an Internet connection with a ping test speed under 100 ms with 0% packet loss. If you plan to engage in things like complex, multi-player, online games look for a connection that responds quicker than 50 ms. If your ISP responds more slowly than 150 ms or is losing packets, you are probably dealing with a problem that your ISP needs to be aware of.
