A handy tool to test your internet connection for “bufferbloat”, the error condition involving “undesirable high latency caused by other traffic on your network. It happens when a flow uses more than its fair share of the bottleneck. Bufferbloat is the primary cause of bad performance for real-time Internet applications like VoIP calls, video games, and videoconferencing.”
(My home internet connection is currently rating a C: “your latency increased considerably under load”, jumping from a min/mean/p95/max of 10.7, 16.9, 23.7, 30.1ms to 35.3, 98.4, 121.0, 286.0ms under load, yikes, so looks like I need to do some optimising.)
