Log out of the main website before loading the speed test. That will load the HTML5 test.

Ah, that's better- thanks.

"A" in both directions

Clunkier than AOL 3.0 when doing downstream, Upload well it failed to even bother.

Grade F is a far cry from what DSLreports gave me

Well have changed nothing to do with the actual test, the A/B logic has been present for over two months. So if test has run for you before and not this time, something else was up

Is the latency shown that achieved with or without the tests running? I guess it is WITHOUT as I get 10ms and F/D or F/E ratings!


Need to trying on another PC to see if this one, running XP and FF is the problem.

Latency is the figure from when no testing is underway.

Entirely possible to have an otherwise great connection and get poor ratings for the buffer problems due to CPE or a large buffer somewhere in the system.

On TBB test I get B down and E up.

Excellent news! I'm glad to have the latency detection in the TBB tester.

When I turn off the SQM/fq_codel in my router, I get an F for bufferbloat. But when I turn it on, I get an A in both directions.

,,, In case someone thinks I'm bluffing here is the March 2015 data just posted onto twitter https://twitter.com/thinkbroadband/status/5938192551...

The difference between providers with respect to upload and download performance is interesting.

Allowing that I don't know for sure what the figures on the charts mean (multiplying factors?), my ISP (IDNet) would appear, at best, to be no better than average- 4.9 up and 3.3 down.

My own tests (this morning, within a few minutes of each other) give an A both up and down for the tbb test and B on the DSLReports test, which I would assume is good.

So I'm not sure what the figures on those charts imply... That most IDNet users have rubbish routers? That a lot depends on the route taken to the tbb servers? Something else entirely?

Could you give a brief outline of how (or even if) these charts should be used in comparing ISPs or choosing one?

(Fair enough if you'd prefer to leave it until the FAQ is sorted.)

On my VM 100Mbps I get an F
On my BT 40/10 I get a C

I use a Draytek 2920 with the VM Superhub in Modem Only mode and the BT VDSL modem box plugged into the WAN ports.

I guess from this then that buffer bloat is a modem issue?

Need to do some digging ... other PC gives same results.
