Had planned an evening on a Virgin 50/5 connection trying out a nice methodology and a bit of tweaking to give tbbMeter a bit of an exercise, but Virgin congestion meant it was useless, but carry on regardless I say.
This is not about being able to say our tester is better or worse than ABC's, but rather getting an understanding of what is going on so everyone can benefit.
What would be useful
1. Ideal world, someone happy to let me have remote access to a PC desktop that has tbbmeter installed, for an hour or so testings. Yes a remote session will affect things, but can allow for that in conclusions. Failing that if someone is in the Surrey area, a rare visit is possible, will bring cookies.
2. When people do speedtests, if the tester has a traffic graph capture it, as well as the numbers.
3. Use tbbmeter or other graphing tools, e.g. Windows task manager to compare tests
4. Our tester usings a custom protocol that we know is hit by BT traffic management sometimes. So using test files from http://www.thinkbroadband.com/download.html can be useful.
5. In tbbmeter there is an auto test, CTRL SHIFT F2 starts it, and this does 20 second pings, upload, single thread download, multiple thread download, 20 second pings. The tests then appear under Statistics Speedtest results.
6. tbbmeter lets you manually do an upload test.
7. Test at peak and off-peak times.
8. Give up on wireless, Ethernet rules these days for the 80/20 product in particular.
9. If behind a NAT router, safe enough to turn off your software AV/firewall for a short period, so long as you trust others on your LAN, and ensure this is not impacting your results.
