Why has the internet speed test Ookla in the results, between the app and the results in the browser, only about 30% download speed?
System: WIN 7 / 32 Bit The high different of the speedtest results are also without the firefox add ons and with other speettests. Thus, the cause of the difference in speed can be found on the way from the network card to the browser.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 6.1; rv:66.0) Gecko/20100101 Firefox/66.0
Are you running the latest version of Mozilla Firefox? You might be running into a compatibility issue. Try updating your software to see if it corrects the problem.
Actually do you mind posting your speedtest results? I'm noticing there is a slight difference in upload speed between the browser and the app. Also where did you download the app from, Windows store or a standalone version?
The app is from the manufacturer Ookla, as well as the online browser application with the setting on the identical Reverenzserver.
P.S.: The results are as follows (only download / upload ist ok: Speed of internet providers on the router: 280 MBit / s. Speed on the app Ookla (without browser) 260 MBit / s Speed online in the browser 70 MBit / s. The information is hopefully helpful ...
System: WIN 7 / 32 Bit.
The high difference of the speed test results are also without the Firefox add-ons and with other speed tests.
Thus, the cause of the difference in speed can be found on the way from the network card to the browser.
Try this site, NetFlix Servers:
You can let the first test run or stop it and set the Parallel Connections to what your Modem has in Bonding Channels, if you know what this is and if your ISP supports it.
Example: I got an old Modem that has 4 Bonding Channels. I set the Parallel Connections to 4/4.
My Local ISP has since upgraded to 8 or 9 (and probably more later) Channels. I'll upgrade the modem at some point in the future.
This Test site accurately comes up with the speed I'm subscribed to when I set the Min/Max Parallel Connections to the number of Bonding Channels my Modem has - which is 4.
My brother has 16 Bonding Channels with his ISP, which his speed subscription is only 20Mbps, yet he can stream NetFlix 4K Movies just fine.
I'm subscribed to 60Mbps InterNet Speed. I often see peak DLing of 65+Mbps in Windows 7 Task Manager.
Here are the results of the Fasttest from Netflix ... They are comparable to ookla. Is there still a possibility to check the connection of the Browser to the Netzwekkarte and adjust manually?
For comparison, the results of Ookla in the app and in the browser ...
Some Apps or Test sites will vary on the Speed results. It depends how the App or site setup the test and whether it gives reasonable or poor-design results.
A short, brief test won't give accurate results, especially if an ISP does a high-speed, high-burst of data for the first 20 or so seconds - then levels-off to the 'real' Mbps rate they are giving you.
I don't trust doing tests within Apps. The test results can vary widely probably due to memory 'clogging'. I use a browser (FF) and go to the test site itself. It's best to do this on a direct-connected computer, if possible (not Wi-Fi).
What is your Subscribed InterNet Speed from your ISP?
Another site you may try is the TestMy-Net site: (and select manual Download Test and choose the 200MB File.)
Even here, I think at times it under-reports the speed.
The NetFlix Testing site for me has been the most consistent with 'truer' results using FF because I believe NetFlix has the 'bandwidth' and servers to handle the high-visits. (Which is why I can view there 4k Dolby-Vision movies or series without any drop-down in speed/resolution 99% of the time.)
Unlike other video streaming services, where they are not setup for high-peak demand, so their streaming is poor a lot of times with picture break-ups and the resolution bouncing down/up, etc.
However, at times, the NetFlix test results can be way under-reported when I run the Android App version (of Fast.com). So, I always trust my results at my Windows 7 computer, which is hard-wired connected to my Router.
