Re: Bufferbloat?


[re: Daemon66] [link to this post]
 
That is what the theory says and I can only share what we see from observation means that while high TCP latency usually indicates high periods of ICMP latency the two numbers can be different absolute values with the ICMP generally being lower.

Also as 'ping' usually implies ICMP echo to most people I was being open and upfront by saying small TCP packet.

Could go one worse and call it a "gaming style ping" !!!

For those worried about the grades http://www.thinkbroadband.com/speedtest now has an analysis button and shows the individual latency measurements and a couple of other new bits

is it possible to have the grade show without analysis been clicked?

I noticed now I have to click analysis to see the grade. I like of course the extra information tho. smile

Also the quality score seems a bit whacked?

"Quality at 228.83 is worse than the average 1.51 on your ISP using VDSL2/FTTC " It may have happened as I noticed the start of the speed graph was about 1.2gbit/sec then dropped to my actual speed, I guess thats why I had the weird quality score?

--edit--

confirmed smile second test didnt have the spike and now get this

"Quality at 1.00 is better than the average 1.51 on your ISP using VDSL2/FTTC"

Only got a B grade for download on second test as first latency check spiked high, does that mean I need to work on my QoS setup or I should blame tbb tongue

Spiking is something am looking at, and by exposing the score to individuals we'll get more feedback as people raise their oddities (theory is that the adverts are causing a side-effect, this is not affecting speed figures but makes graphs a bit odd at start and skews quality), was not noticeable so much on old site format even with same speed test code.

On the A-F grade do I worry if I get C grades no - it just reminds me that if doing multi-gig downloads don't also expect my uploads or gaming traffic to be totally unaffected.

'Back to Main Graphs' button also not working for me.

Firefox 53.0.2 running on Windows 10 Pro 64 bit.

Tried it on IE 11 and works okay on that.

If you want to deal with bufferbloat properly then you will need to put your virgin hub into modem mode and get yourself a decent router with QOS, this will protect you from buffer bloat by prioritising packets entering the buffer and prevent any lagging too far behind, in reality I don't think you need to be worrying about this at all by the sound of your usage, and if you have the Hub3 you will be stuck with a certain amount of lag from the Puma 6 CPU bug anyway and you won't get around that, however from what your saying that doesn't cause any noticeable problems for you, so my suggestion would be to just stick with what you have, bufferbloat shouldn't be a noticeable problem to you from the description you have provided.
