TBB Speedtest seems to give strange results on Safari, particularly latency and upload speeds.
Here is a result on Firefox: 54ms; 6.9Mb/s down; 0.52Mb/s up
Firefox
On Safari: 125ms; 6.9Mb/s down; 0.35Mb/s up
Safari
On Firefox, using Flash: 60ms; 7.0Mb/s down; 0.76Mb/s up
Firefox Flash
On Safari, using Flash: 123ms; 7.1Mb/s down; 0.35Mb/s up
Safari Flash
So which is correct and why the 100% differences?
I have, of course, done multiple tests and the differences are systematic, not statistical variation.

What is Firefox flash? If running on a page that talks about flash, its not really Flash, but same test these days
https://www.thinkbroadband.com/speedtest/15978436735... Safari
https://www.thinkbroadband.com/speedtest/15978437053... Firefox
No big difference here. Suspect something to do with how the browsers may be handling the traffic i.e. imposing extra latency in some scenarios but with slightly faster connections this becomes so minor to not be visible.

Thanks
FirefoxFlash is the TBB Flash speedtester accessed from Firefox.
It may be that the differences are smaller for links with higher upstream rates, but a latency difference of a factor of two and an upstream throughput difference of more than a factor of two seem to me to be significant.
I tried the same comparison on speedtest.net-
On Safari: 32ms; 6.93Mb/s; 0.85Mb/s
Safari
On Firefox: 32ms; 6.75Mb/s; 0.85Mb/s
Firefox
No statistically significant difference.

There is no flash speed tester anymore hence the question. What URL?

On the Tools - speedtest page, scrolling down, "Our old version is still available if you want to run out Flash based tester, but this no longer links to your profile".
The link leads to a page starting "The speedtester uses a Flash Player and if our tester does not load or fails to run we recommend checking you have the latest version of Flash installed and enabled in your web browser ...."
I don't know if that is still true or if the link runs the normal test, but it just gave this result.
The standard Tools >> speedtest link gave this result.
Both run over wifi to a Three HomeFi Huawei B311 wireless router.
My mobile phone on its own 4G+ gives far better of course. Well over 120Mbps on the multi-stream, 60'ish on the single stream.

Have updated the FAQ to remove the old links
If the original poster is up for some time just running tests then might be able to produce a specific version that can be tuned to their scenario in the presumption that others using the same browser will also see the same when using ADSL/ADSL2+.
The version of OSX which may be partly behind why the different behaviour and is a rare beast in the result.

Yes, the link I was using is http://labs.thinkbroadband.com/flashipv4/ which came from the text:
Alternate Speed Tests
The test by default is performed over SSL. If you want to test standard HTTP performance we suggest using our standalone HTTP test.
Our old version is still available if you want to run out Flash based tester, but this no longer links to your profile
I have found the differences in upload speed and latency using the TBB speed tester relative to speedtest.net and the flash tester on OS10.11, 10.12 and 10.13, with Safari updated to the extent possible to support end-point. The system that produced the numbers I quoted was OS10.13.6 with Safari 13.1.2 and Firefox 79.0.
Hope this helps.

I've just removed them from my post as well  .
Also please see a relevant PM in a moment .

Need to see what difference this version makes to what ajseeds is seeing

And now https://labs1.thinkbroadband.com/hs and also http://labs1.thinkbroadband.com/hs
Two links as interested in seeing what difference there is between SSL and HTTP and tweaked one other setting. The upload should be more granular
Also can you confirm what your actual sync speeds are.

A quick check on the first link with Safari gave
https://www.thinkbroadband.com/speedtest/15981678057...
(note these are tests on a slower line than earlier tests- 564kb/s upstream)
The second link was broken for me?
The sync. speed on the first set of results I posted was 8Mb/s downstream, 1Mb/s upstream.
I'll now try the second link on Firefox.

Alwyn

564 Kbps so best would be 500 Kbps so not going to investigate these tests any further

Dear Andrew,
Sorry, if I was not clear- the original post related to an 8Mb/s; 1Mb/s connection.
I will try the links you sent on that connection, when I have access to it again.
The second link you sent appears to be broken.
Regards,
Alwyn

The second link you sent appears to be broken.
Both links work fine, your browser is probably blocking the second one due to its not secure (i.e. not using https / SSL etc)

Second link previously had a missing "s"
Corrected link works fine, as you say.

Exact upload sync speed is?
Initial conclusion seems to be that SSL has higher overheads for your version of Safari compared to Firefox.

Ah, must of been corrected the time I checked it

Not the OP, but here are mine run from an iMac with Eset Cyber Security Pro running using Safari:
The http version really impacts the uploaf speed.
Https result:
https://www.thinkbroadband.com/speedtest/15982240044...
Http: result:
https://www.thinkbroadband.com/speedtest/15982239684...
Happy to run results on Firefox if required. Chrome always produces poorer results.
|
|
|
|
Sync. speeds: 1,008 kb/s upstream; 8,095kb/s downstream.
Rather odd that some results have upstream peaking above sync speed- presumably that is loading the buffer?
All goes to show that choice of browser can affect results significantly.
|
|
|
AV may be doing more checking on http data than SSL i.e. it will see the SSL and trust the certificate and do less checking possibly

Which speed test of ours has reported an upload speed above the sync speed?
If other testers are doing that I don't care, as not my job to fix their services for them.

This is the TBB result where peak speed exceeds Sync. speed:
https://www.thinkbroadband.com/speedtest/15982174938...
1.1Mb/s with a Sync. speed of 1.08Mb/s
I think the issue of buffering may be important. Perhaps a longer upload test is needed at these low bit rates to get a reliable result?
|
|
|
That was burst - so buffering is an issue and longer test would not fix that.
