  1. @mudmanc4 maybe not a bad idea - I think I have Dallas selected by default, but maybe some other ones. I'll post after some decent period of testing what happens. Thanks for the idea. @xs1 I don't get what you're saying. It looks like TestMy is showing results consistent with the other 2.
  2. The speed tests I use regularly are: Comcast speed test (Ookla)* http://speedtest.xfinity.com Google Fiber http://speedtest.googlefiber.net/ Speed Of Me http://speedof.me and this site. * - I know Ookla is skewed - they do the test, then discard the bottom 30% of results and top 10% - this means the average speed shown is higher than a true average However, the 3 sites above all show consistent speeds from 90 Mbps to 120 Mbps. As soon as a test completes, I then run both Multistream and single stream on TestMy.Net, and I get about half (e.g. 63 Mbp
  3. Single thread shows 77 down, multi shows 79.9 down from the same browser at similar moments in time. But apps and browsers are typically multithreaded, and that threading utilizes the bandwidth more fully, testing its peak performance.
  4. Thanks, that was it! I didn't realize that all those locations were checked, and that meant it was testing them all. That explains it. I have to still disagree with you about single/multi thread, I think multi thread is the best way to test and tell what my pipe is allowing. I do understand there are technical differences in the different testing web sites, but at a gross level, at least you return stats on all the packets (rather than Ookla). And, you use PoP servers, instead of geographically-close servers.
  5. Ever since the first week in October, TestMy.Net has shown a very large (slower) result than SpeedOf.Me and SpeedTest.net. For example, the other 2 are showing 85-90 Mbps Download, while TestMy.Net is showing 25 Mbps. I turned on Multithreading, and they are running from the same browsers. I tried Internet Explorer 10 and Firefox from Windows 7, plus Safari 9 and 8 from OS X 11.11 and 11.10. Are you aware of any system issues with your infrastructure that would cause that problem? I know, for example, that SpeedTest has local servers and discards a disproportionate portion of the test res
  6. @editorsean, all great points. My suggestion was that with a slower connection, the disparity is smaller, and conversely bigger with a faster one. Also one small correction, you stated to multiply by 8 to figure Mbps - actually you should have said multiply by 8 to figure MBps, but Mbps is typically how line speed is measured, while MBps is how throughput is measured by application software (like web browsers), but truly it is confusing as all hell because take for example Filezilla, it measures in a completely different base of measurement - KiBps (Kibibytes per second), which is the comput
  7. I had been choosing 100 Mbps on TestMyNet. The other 2 sites don't let me choose sample size. In contrast to what you say above, when I test 6 MB sample size, I get a slower speed (30 Mbps) than when I test 50 MB and 100 MB, where I get 57 Mbps and 60 Mbps respectively. And that makes sense intuitively, as a transfer of large data is typically faster than lots of smaller data, simply because of the overhead in establishing and de-establishing communications for the data transfer.
  8. Another thought here, up until recently my ISP was AT&T with 18 Mbps, and the 3 speed test web sites I used showed pretty much similar speeds when testing. Now that I have Comcast with 50 Mbsp, maybe that is why there is more disparity with the speed tests - because it is a higher bandwidth (and slightly different line technology). I am testing around 40 Mbps with TestMy.net single-threaded test, while multi-threaded is showing almost 60 Mbps. However, don't web browsers and download managers download multi-threaded anyhow?
  9. That is a lot to think about, thanks for that fantastic reply. As a "lay" person with regards to net speed, it seemed to me like a simple "what's my speed" question, and I did not realize the complexities (and misleading methodologies in some cases) involved. I'll also try running Performance Monitor and Activity Monitor on the systems I run speed tests from, but since I have 6 people relying on the connection, I don't think I will attempt the disruptive complete disconnect/reconnect. As far as OS X, I do have all machines set to update to the latest (the one I primarily test from is 10.11)
  10. I regularly use 3 sites to test my network speed: Ookla (flash-based), SpeedOf.me (HTML5-based), and TestMy.net. However, the first 2 seem to report similar results, while TestMy.Net reports very different (and slower) results. Ookla I can rationalize, as they have local servers that might give lower latency. SpeedOf.Me correlates to Ookla. I am regularly getting 52 - 60 Mbps download, and 10-12 Mbps upload. However, when I run TestMy - I see 10 Mbps down, and 8 Mbps up. WAAAY off - this is the auto test. When I run the Download only test, I got 39 Mbps down, which is still way o
