  1. As my Internet connection throughput intermittently dips due to running on a cellular 4G network, I was curious to see how well the Internet Speed Meter app handles fluctuating traffic. From running linear and multithreaded tests with TestMy, it corresponds reasonably well with TestMy on download tests. Things got a little interesting when I ran Ookla's Speed test where my connection throughput fluctuated during the test. Here are the two full-screen screenshots. In the above graphs, I drew in horizontal lines for each 0.5MB/s. In the graphs below, I drew the green line based on the download test result divided by 8 for MB/s, calculated to the nearest pixel: _ The reason I picked these two graphs is that the traffic graphs were very similar, apart from a deeper dip during Ookla's speed test. That didn't stop it producing a faster result! These graphs clearly show the two different methodologies these speed tests take. To my eyes with the left graph, the area of the spikes above the green line will roughly fill the valleys below it. So I have no doubt I was averaging about 22Mbps at the time. As for the right graph, there's no way I was averaging 23Mbps during that test. This is a clear example of Speedtest's methodology "The fastest 10% and slowest 30% of your results are DISCARDED". During this test, I saw the speedometer hit 26Mbps briefly before dipping to the low teens for a few seconds, then gradually climbed until it hit the 23 figure just be fore the download stage ended.
  2. As Android does not show data traffic in realtime like Windows does, I recently bought an App that does. The main purpose here is to check how my cellular based ISP (Three Ireland) shapes traffic as some sites such as Cloudflare traffic are clearly prioritised. Have a look at these two traffic graphs and let me know what you think the average download speed is for the blue line of the first and second graph: Ignore the grey line, which is upload traffic. The throughput variation is related to my ISP as 4G is a shared medium, but I'll will explain why I picked these two later. 😁
  3. While CCleaner can wipe the Firefox cookies, cache, history, etc., it only gives the option to compact its databases. The growing database sizes was the problem I had with Firefox slowing down on my PC after a year or two of regular use, despite regularly running CCleaner. In the past I thought it was just Firefox getting bloated with its larger installation sizes, but noticed that Firefox and Chrome performed about equal on my seldom used laptop. Usually every 6-12 months, I would backup my Firefox bookmarks, then rename the "Profiles" folder in "%appdata%\Mozilla\Firefox" and "%localappdata%\Mozilla\Firefox", e.g. to Profiles.old. When I launch Firefox, it acts like it's freshly installed and I import my bookmarks and reinstall the few plug-ins I use. If all seems fine after a day or two of use, I then delete those old Firefox profile folders.
  4. If it's a Mozilla based browser such as Firefox, I suggest deleting the App data also every couple of months so it's like it's freshly installed. Just make sure you have your bookmarks synced or backed up first. Firefox stores browsing history, cookie details, cache metadata, etc. in databases. Clearing the cache, cookies and other privacy data within the browser usually does little to reduce the database sizes. With the Firefox desktop browser, it's surprising just how much better Firefox performs with its user profile directories wiped after 6+ months of use, so it's very likely the same with its mobile browser app. To gave an example of how much Firefox leaves behind just clearing the privacy data within the App, these were the Firefox App storage details: App size: 175MB User data: 0.97GB Cache 663MB Total 1.81GB After clearing the Firefox cache & cookies within Firefox, the Firefox App storage details reduced to as follows: App size: 175MB User data: 0.97GB Cache 124MB Total 1.27GB In Firefox, I checked that my bookmarks were synced and then cleared the Firefox's App data (Phone Settings -> Apps -> Firefox -> Storage -> Clear Data). When I went back into Firefox, it was as if I used Firefox for the first time on the phone, so I signed in, let it restore my bookmarks and signed in to a few sites (e.g. TestMy). When I went back into the Firefox App storage details, they were now down to: App size: 175MB User data: 47.28MB Cache 42.60MB Total 265MB
  5. Some of the wireless internet service providers (WISPs) that operate here in Ireland operate on the 5GHz Wi-Fi band. This is basically like a home Wi-Fi set up, but on a much bigger scale. The purpose of the dish is provide a high enough gain to pick up and transmit the signal over a several mile radius. The tower usually consists of several sector antennas, typically three aimed 120 degrees apart operating on separate channels. Customers on one sector generally share the same channel like on a home Wi-Fi network. The last WISP I was with used Ubiquiti hardware. When I changed provider, I was curious myself to check out its web interface and to my surprise they never changed the default password on the dish hardware's web interface. Its configuration was very similar to home Wi-Fi, mainly an SSID, WPA2 passphrase and internal IP address set. Their service end likely had a gateway server that throttled the up/down bandwidth according to whatever package was ordered, while also metering the usage from the assigned IP address. Ubiquiti has a training book freely available on their website which goes into detail on how enterprise Wi-Fi works including on a large scale that WISPs use: https://dl.ubnt.com/guides/training/courses/UEWA_Training_Guide_V2.1.pdf A few other WISPs here use LTE on the licenced 3.6GHz band. This basically works the same as a mobile phone LTE service, but where the operator has exclusive control over its assigned spectrum, LTE hardware and installation. As this is a managed network, it generally performs a lot better than a mobile phone LTE network as each LTE client device (i.e. that dish antenna on the roof) is professionally installed, maximising the signal encoding efficiency. The weaker the signal quality, the more airtime is required to transmit the same amount of data.
  6. Indeed, I have been using Firefox Nightly as my main browser on my phone for probably the last 2 to 3 years, so pretty much all my testing was done in this browser and also in the Chrome mobile browser. The new privacy notice is better and indeed the bottom-right thingy is gone once I touch continue:
  7. This is the server response page. I forgot to mention the browser is the Firefox Nighly version, which I have been using it for a few years. So this could have been a nightly update that triggered this issue.

  8. I noticed this morning that TestMy started showing the old version on my Firefox mobile browser. Whenever I switched to the Old site, I could easily switch back, but I notice that the new site button is also missing, but still is there in the Chrome app. I cleared my Firefox's cookies/cache, but it still loaded the old site. i.e. the 'New' button is missing in the left image from Firefox, but shown at the bottom of the right image (Chrome).
  9. An expiring cookie would certainly help as this way if I leave the site for a few hours, I'll not get caught out like yesterday. Another thing that would help is show the chosen date range like what the Hourly Average page shows. For example, in the left screen above, it shows "01-01-2019 / 01-31-2019", but on the My Results screenshot above, it doesn't mention this. If it's not difficult to implement, I would prefer the month shown as a few letters, e.g. 'Jan' instead of '01'. Here in Ireland (and rest of EU), we read dates as DD-MM-YYYY. While '01-31-2019' is clearly written as MM-DD-YYYY, I would read a date like '01-12-2019' as the 1st of December, 2019, whereas 'Jan 12, 2019' would be clearly the 12th of January, 2019.
  10. I noticed that the upload progress meter bar on the light theme shows a fully lit bar throughout the upload test. For example, the following is roughly 1/3 through a 12MB upload test: It works fine in the dark theme: For the date selector on the Average Hourly page: I'm not sure if this is a bug or just a quirk, when I select a date range, it does not reset to default when go to the My Results page later on, until I touch 'Default'. This caught me out yesterday when I was trying to view my test results and couldn't figure out why it was not showing the latest test results or even results from other providers I tested with. As I was about to report the issue, I happened to notice the date selector still had the date selection from when I visited the Average Hourly page earlier. This issue is easier to demonstrate in the mobile theme. On the first screenshot, I went to the Average Hourly page and selected all of January. This shows my January hourly average as expected. In the second screenshot, I went to the My Results page. It is only showing the test results for January, i.e. the date range I chose on the Average Hourly page: If I touch that red Default button, it shows all my results again. However, it would be better if it cleared the date range automatically once I left the Hourly Average page.
  11. With me, it's similar with running speed tests at night, such as while travelling with someone in a car or on a bus. Even with my phone screen dimmed to minimum, a white page background still gives off plenty of light. This is especailly noticeable when I switch back and forth between the signal meter app (Network Cell Info) which has a black theme and then back to TestMy on the web browser. This is where I like the dark theme. On my PC, I'm happy with the regular white theme particularly during the day time. So with me, it's difficult to say which theme I prefer most as it depends on the situation, a bit like giving my preference on whether I prefer the room light on or off. ? Edit: One issue I've run into with the dark mode is the Express Test does not show the progress meter and the percentage stays at '0%' until the test completes: It does this in both Firefox, Chrome and on my mobile Firefox browser also. The does complete successfully despite showing no progress. The regular and fixed block size tests show the progress fine in the dark mode.
  12. It successfully completed all 5 iterations this time in the old theme: I forgot to mention earlier that it was sending me 3 e-mails each time it completed the auto test in the old theme and just a single e-mail in the new theme. This time it sent just one e-mail in the old theme:
  13. I rechecked and it's now gone from the auto-test header in the old theme. I will see whether it affects how many iterations it goes through and update this post. Currently test #1 of #5 in 5 minute intervals, combined test with a 30MB block size in both directions.
  14. I cleared the Chrome cache/cookies, logged back in to TestMy and started another auto-test with the same parameters, but it's still showing the blue 'Privacy settings' thingy there: It is not there in the new theme:
  15. I gave this a try on my end in a few browsers including Brave (freshly installed) with the old and new theme. The main difference is I chose 30MB instead of 200MB for the download as my connection is a lot slower. In Brave, Chrome and Firefox with the old theme, it ran tests #1, #2 and #3 and skipped tests #4 & #5. However, it did not restart or get stuck with any test. I tried with the new theme in Chrome with the same set up and it ran all 5 test iterations. To double-check it was skipping tests #4 and #5, I took a screenshot on the third iteration in the old theme: After it ran this third combined test at the 9:04pm, it showed 'Done!' followed by an e-mail. The following is the results page showing the three combined tests and an arrow pointing to the third test time. Interestingly the tab shows 'Test 5 of 5' even though it skipped #4 and #5:
