I remember ages back when I was on 50Mbps that TBB only showed about 30 where others showed the full 50. At the time I put that down to iffy peering. These days it agrees well with other testers for me What "meter" are you talking about that shows your running at full tilt?

Thanks. I'm viewing flat and replied to the first response on duplex which I have heard of but didn't know the consequences of which when pointed out are pretty obvious.

Must be a measurement error in the client then I suppose. Strange.

The maths in the flash client are fine, something is messing with the data feed to the calculation side, figuring that out is the fun part.

If the maths in the client has a systematic error we would see it on all connections.

I know that some AV buffering can screw things up - usually causing multi megabit over reporting with some testers.

I have no reason to believe that the reported results I see are wrong - when I did complain ages back that the TBB test was under reporting I could see that the connection genuinely was running slower to you than other testers. That doesn't happen now and never was conclusively explained but my suspicion is a peering route running overloaded (probably because somebody else said it was).

Ignore anything from the days of the old tester when it just ran one download test.
