Pretty much exactly the same as I was seeing (pre-tweaks).
What are you getting with the single thread visualware tester? Somewhere close to the TBB tester, I'd imagine.
TBH I'm still not convinced my tweaks have actually achieved anything.
I had a big boost in the Flash based testers (BB Max, Speedtest.net, speed.io, etc.) following Batboy's advice of disabling vlan 130 in the modem (I think it was 130 - in any case, there's only one vlan set up in the Echolife modem) and disabling QOS (also in the modem).
Now, providing I don't pick a duff server, the Flash based testers pretty much always return maximum speed (before I got results anywhere between 12Mbps & 50Mbps during peak times, but always got max speed off-peak).
I still had single thread issues (pretty much exactly the same as you're seeing).
So after a recommendation and a bit of Googling, on Friday evening I carried out steps recommended by Speedguide.net
Now it may be a coincidence and plenty on here will say it makes no difference, but I immediately got an improvement in single thread downloads which has stayed.
I'd never managed higher than around 6-16Mbps for the TBB test files (downloaded, single thread, using TBB Tools), which was also the case immediately before my tweaks.
Immediately after, I got around 50Mbps for a TBB test file in single thread mode.
TBB test files are still all over the place but I've not had a result lower than 30Mbps since I tweaked and couldn't get a result higher than around 16Mbps before the tweaks.
Coincidence? You be the judge.
During a 13 minute window, starting at 20:25 (Sunday evening) I got the following results (tested in the order shown below): -
74636kbps/16735kbps from BB Max.
64.34Mbps/17.46Mbps from Speedtest.net (Xilo Maidenhead server - probably!)
72.1Mbps/18.5Mbps from the single threaded Visualware tester
74.6Mbps/18.3Mbps from the four threaded Visualware tester
73Mbps/16.06Mbps from the BT speedtester (also confirming my IP profile of 77.39Mbps
And, as usual, the lowest result comes from the TBB tester
TBB Tools download tests give;
Single thread = 36Mbps
Ten threads = 70Mbps
Using Zen's test files
(using TBB Tool to download and meter) I get;
Single thread = 71.6Mbps
a) What's wrong with the TBB speedtester to give such low download results?
b) What's up with the apparent 7Mbps upload limit on the TBB speedtester (only get a true speed if i get my old XP laptop out, when the TBB speedtester returns around 14-16Mbps upload)?
c) How come TBB tools can download a 100MB file from Zen @ 71.6Mbps but can only manage 36.3Mbps for a 100MB file from TBB's own servers?
