Well I have had the XR500 for well over a month now, and I have waited till now to mention it. As I wanted to test over a period of time, and see what result's I come up with.
I have noticed when using the dslreports speedtest, my result's are better without "Anti-Bufferbloat", then with it enabled. Which honestly is a bit backwards, and should be the opposite. I have run many of tests the past month, or so, and everytime my bufferbloat results are better when I leave my speeds uncapped. I plan to post the results of two recent tests in this post. One without it, and the other with my speed's capped to 25% of my overall total bandwidth. As you will see bufferbloat isn't exactly improving "bufferbloat" when enabled.
I actually recently been paying close attention to the test being run, and with Anti-bufferbloat enabled. During the upload side of the testing, the latency average increases, spikes a lot more often, and higher. Which when you think about it.. With me having my limit's set to 25%, I can only use a max of 7.5-7.75mbps of upload bandwidth. I actually get 30-32mbps by my provider. So overall, latency, and ping spikes should stay very low, and consistent. Currently that isn't the case, and I feel whatever the issue is, it's router side.
Because testing without it, latency, and spikes, are much less. This is while maxing out my upload at 30-32mbps, which would be the time for my latency to be at its highest, and spike the most. However that isn't the case. So at this point in time, I feel using "Anti-Bufferbloat" is a waste, and isn't doing exactly what it's designed to do.
Here's a test done without Anti-Bufferbloat:
Here's a test done with Anti-Bufferbloat, with my limits set at 25% of my total bandwidth:
As you see Anti-Bufferbloat isn't exactly making things better. Now I will show you the "Grades" graph the test gives you for each test.
Overall this isn't what I would consider result's you should be seeing with a feature that's considered to help with this. These result's, show it isn't helping at all, only making it worst. Finally here's direct links to both of these test's, for the ones who are curious... I have nothing to hide, and so I will provide the links to show you all, nothing is being doctored on my end. I want to see what the netduma guys have to say about this, and why it's happening. Because currently.. This isn't helping, and I'm better off not using "Anti-Bufferbloat".
