Bufferbloat from dslreports
Bufferbloat is a common problem. It is not something your ISP is going to solve for you. If you are interested in where this grade comes from, what impact it can have, and what you can do about it, please read on.
The test continually checks latency from start to finish (not just at the beginning, like most other speed tests). If the latency rises dramatically during the download or upload section, it indicates your connection has become less responsive when fully loaded. This is bufferbloat. The degree of excess latency generates a bufferbloat grade between A+ (none) and F (heaps!).
Bufferbloat is undesirable latency caused by routers and cable/DSL modems buffering more data than necessary. It occurs at any bottleneck in a network: the most common place is the connection between your router/modem and your ISP.
Bufferbloat is undesirable because it interferes with the smooth operation of your network. You may have noticed it when, say, you run a backup to the cloud. Interactive applications become slow to respond. Web browsing, even to relatively uncomplicated pages (like gmail), is annoying. VOIP services may degrade or even stop working. Gamers can lag out. You may have become used to this, perhaps even considered it normal, but now that the problem is understood, there's a solution.
To fix bufferbloat, the router at the bottleneck must control the amount of data that's being sent so that it doesn't build a big queue. To do this, you can (a) turn on some kind of smart queue management (fq_codel, PIE, etc.) in your current router; (b) re-flash the router with new firmware that will do this, or (c) replace the equipment with a more suitable device. Although your ISP is unlikely to help fix any individual case of bufferbloat, they may (and should) be working to introduce better firmware and hardware to reduce the problem for all their customers.
