Downloading the big file, the user for certain wants to know, what is the time it will borrow. Some programs show the speed of downloading and estimated load time, others are not present. In the latter case it is necessary to resort to the simplest calculations.
Instruction
1. Many download managers are created taking into account requests of users therefore show as already spent for downloading, and approximate remained time. For example, the programs intended for downloading of files from torrents quite so behave. In addition to time also the percent of loading of the file is specified that allows to evaluate the remained downloading time rather precisely.
2. If you download the file without use of specialized software, load time can be defined, knowing the file size and speed of downloading. For example, if the file size of 100 megabytes, and the speed of downloading is equal to 50 kilobytes per second, then time will be equal: 1024×100/50 = 2048 seconds or is slightly more than 34 minutes.
3. Remember that the speed of the Internet and actual speed of downloading are different things. For example, the speed of your connection is equal to 100 megabits. As in byte of 8 bits, 100 megabits = 12.5 megabytes per second. It means that you should download the file of 125 megabytes in size in 10 seconds. But the actual speed of downloading of files is usually equal to 50-150 kilobytes per second. It is influenced by a set of factors including load of the channel of the server from which you download the file. Therefore you watch the actual speed of downloading and already on it calculate load time of the file.
4. When downloading big files and the qualitative Internet surely under-exploit a download manager, for example, of FlashGet. Similar programs not only help to control the speed of downloading and the remained time, but also allow to dokachivat the file at communication break. Consider that downloading time always is approximate and depends on change of speed of downloading.
5. In certain cases for acceleration of downloading it is possible to use the high-quality proxy server. Having the good channel, it will quickly download the necessary file and will transfer him to you. As a result downloading will take less time, than without use of a proxy. This way is useful if you have a slow connection.
