Port 5. 05. 0. The three stages of the test are Ping, Download, and Upload. Ping (Latency) Test. This test is performed by measuring the time it takes to get a response for a TCP request sent to the server. It is done 1. 0 times with the average value determining the final result. Download Test. A small binary file is downloaded from the server to the client to estimate the connection speed. Based on this result, one of several file sizes is selected to use for the real download test. The download test is performed with cache prevention via a random string appended to each download.

Speed is measured up to 3. Ordered samples are looked at through a sliding average window to eliminate anomalies and determine the result. Upload Test. A small amount of random data is generated in the client and sent to the server to estimate the speed of the connection. Based on this result, an appropriately sized set of randomly generated data is selected for upload.

The upload test is then performed in chunks which are pushed to the server. An overall average is used to determine the result. The Speed Test is a true measurement of speed between the web server and client.

HTTP Fallback. In the case that TCP Port 5. Speed Test will fall back to using HTTP on Port 8. You may notice a slight delay when initiating a test.

What is a speed test? It is the fastest and simplest way to measure the speed at which your ADSL line browses. This way you will know the upload and download speed and you will be able to know the efficiency of your connection. It is important to do a speed test to measure the download and upload speed of your connection especially when you notice that the pages take a long time to load or your P2.

P programs do not download to the download speed you're used to. Read before starting the Speed Test. For the results of our speed tests to be as reliable as possible it is important we check that we have no other program using our connection, so we must make sure to disconnect P2. P programs like Emule, Bit. Torrent, Ares, etc..

Bear in mind that in these types of connections (analog modem, ISDN, ADSL, etc.) use various protocols (PPP, TCP / IP) that occupy bandwidth (between 2% and 2. The results shown in this test correspond to the usable bandwidth, IE, this equates to the speed of information transfer, and not to the access speed. In addition there are other no measurable factors that may contribute to reduce the speed of the connection, such as congestion in the network, electromagnetic interference, etc..
