http://tbb.st/148499171149530414066 Note a flash test from January
last flash test I think is the poster http://tbb.st/149021664027528451377
New version http://tbb.st/1492593114493222355 but before site change
http://tbb.st/1495465221201622655 new version with new site
Flash tester had no changes over the time period and that does show single thread not always nailing the test, of course impossible to compare that with ookla since they don't do it.
Applying Ookla system to the test at http://tbb.st/1495584114552256155 would mean we show a download of 172 Mbps and upload 20.6 Mbps plus 25ms latency and nothing else. On tests with no congestion or other issues then usually makes no difference.
