  1. A download manager, torrent, or FTP would typically download faster than a web browser, since they don't have to update the graphical page layout and run JavaScript. Even a direct linear download (or a few of them) via the same browser to disk with all tabs closed or inactive would be faster. I've never used newsgroups, but I'd guess those clients are also more efficient. Using modern "web apps" for heavy duty data transfer (web torrent, videos) is strange. I guess they can work if you have a fast space age computer, but I don't see the point. During testing with TestMy, I observed
  2. The forum software is indeed slow. A number of forums have changed the engines within last one or two years, and become slower and more difficult to use. The owners would probably say that they had to update in order to have a "supported" version. I'm sure that the main reason for these updates is to make the sites look like Twitter and Google Plus - "flat", and with strange terms like "content" and "follow" in place of common words like post, thread and subscription. For similar reasons flat "metro" design exists, and applications like CCleaner are compelled to change. Several people complain
  3. Why does selecting a numeric Location from the drop-down list, which has the choices like Home and Office, cause a country flag to be displayed in the results database? If I select Location 2, I get a Swedish flag.
  4. The upload speed test currently doesn't show a "TiP" graph of the speed over time like the download test does. The curve of this graph could allow one to determine the presence and effectiveness of an advanced congestion control algorithm (ctcp, cubic). I would also like a precise readout of the Initial Congestion Window, which is essentially the first data point of the graph. This parameter is now configurable in modern OS, but it can be difficult to tell if the tweak has been correctly applied. In my opinion the upload graph is more useful, because in the opposite direction a TestMy server i
  5. I noticed that on my computer Firefox by default sets the TCP send buffer equal to 128 KB (about:config -> network.tcp.sendbuffer), which limits the result of a single thread upload test. System default receive buffer is used, so download speed isn't affected. This value is adequate for normal web browsing and uploading to geographically close servers, but cannot be used to measure the best possible performance of bulk file transfers across different applications. Usually software don't set custom buffer sizes, or if they do, they use extreme values (FileZilla uses 4 MB). I observed th
  6. Data Throughput - LTE - Software Tools Recommends to use either IPERF or FileZilla. Site includes instructions how to configure FileZilla for high throughput. TELE2 servers can also be used to test the performance of our FTP Server via FXP. They do not allow connections from arbitrary IPs as expected, so we need to initiate the operation from a Client on the same machine (IP) where the Server is.
  7. I was reading another forum and saw a reference to a Speed Test site operated by TELE2. It allows to connect by FTP to easily test the upstream with any number of connections as chosen in the FTP client. Most other sites only allow to test the download speed. I like this very much because I am not a fan of modern "web 2.0 / cloud" technologies. They are often a bottle neck, especially if the browser is tasked with several threads of work at once. You can also verify that the FTP client settings (buffers, windows) are good if experiencing poor speeds your seed box or another server. Curre
  8. They can't make the offer sound nearly ten times worse to the average customer. Everyone expresses bandwidth in Mbit. This way you can know how many streams of video of certain bitrate (also in megabits) it supports. To get the picture, you click on "Share This Result" after a test.

  9. I would add a few points to this case which has mostly been explained by other members already. The peak throughput of a router is definitely finite and quite small relative to a desktop computer. It is a separate from the throughput and power of the wireless radio interface. I was able to find that this router has a 384 MHz CPU in the latest documented revision, and has been tested to deliver 60-80 Mbit over wireless. Wired performance, surprisingly, wasn't tested, but is at least 130 Mbit. Many people nowadays consider router to be synonymous to an access point, which is not at all the ca
  10. Haven't you confused bits and bytes as is commonly the case? What are the exact words and numbers used by your ISP to describe the accesss plan? 2 Mbit equals about 244 kByte, so your tests match the advertised speed. That is quite low speed, but might be normal if you live in a remote location.
  11. It should be full duplex, sending and receiving at the same time. I have not seen such speeds in practice myself until today. I use free FileZilla Server for file sharing across the LAN. FZ was miles ahead of Windows file sharing before they added SMB2. It is very fast on any computer, and can connect obsolete Windows to modern easily. There is one gigabit switch between the machines and the other machine has a Realtek NIC. Simultaneous up/down. Single transfer. I'm always defending the old and proven. Not meaning to offend anybody, just sharing my experience.
  12. Sorry for the double post. I'm very excited about this upgrade from 30 Mbit. Uploads to a seedbox in France and a cable customer in Norway. I'm having no issues with bittorrent yielding to web browsing and light video streaming if I keep the connection count reasonable. I only use TCP and download from at most 8-12 peers at once. Right now there is another user watching some web video in another room and she's not complaining. It's 2 PM local time.
  13. This is my microwave oven about 18 feet away, and a couple bursts of neighbor's wlan. I switched the oven off towards the end of the spectrogram. Now -60 dBm would be a very usable signal in the absence of this interference. Lowest usable for around 10 mbit throughput is -80 dBm. If there are microwaves around, we have not three but only two wi-fi channels on the either side of the microwave peak. Outside of the unlicensed band, there is nothing. Those channels look very attractive for point to point links between buldings between devices supporting it. The lower frequencies also go
  14. SoftLayer, London. I've decided not to push single connection speeds further to avoid "buffer bloat" to closer destinations.
