So it is entirely appropriate in my view to give even "high speed" connections low grades; it's telling you that they suck under load , like when your kid is downloading a video (or uploading one for their friends); your performance (e.g. web surfing) can go to hell in a hand-basket despite having a lot of bandwidth on the connection. For most use, I'll take a 20Mbps link without bloat to a 200Mbps one with a half second of bloat any day.
I will expect that high speed links will have little bloat simply because even large buffers empty quite fast.
Unfortunately, that is often/usually not the case. The buffering has typically scaled up as fast/faster than the bandwidth has, in my observation. You can have as much/more bloat on a higher bandwidth line as a low bandwidth line. That's why I always refer to buffering in seconds, not bytes, unless I'm trying to understand how the identical equipment will behave at differing bandwidths. The worst is usually someone taking modern equipment and then running it at low speed: e.g. a gigabit switch being used at 100Mbps will generally be 10x worse than the old equipment it replaces (at best). - Jim
