sync: 15.897 seconds best time, 25.832 worst timeĪs you can see, the result reaches almost 3x acceleration.async: 17.106 seconds best time, 20.056 seconds worst time.On one of the resources I found, a benchmark was carried out on downloading a Gentoo Linux image from a site of one university( slow server).ĭownload DietPi distribution (fast server): The main function receives a list of URLs from the command line and, using the already familiar asyncio.gather, it starts downloading many files at the same time. After that, the already synchronous pyfileobj method concatenates all files into one file.Īsync def main (): if len (sys.argv) <= 1 :Īwait asyncio.gather(*) await asyncio.gather(*tasks) allows you to execute all collected coroutines concurrently, which significantly speeds downloading. part file, creates a temporary directory under the original file, all parts are downloaded into it. The most basic function gets the filename from the URL, converts it into a numbered. Part_file_name = os.path.join(tmp_dir.name, f', part_file_name)) Tmp_dir = TemporaryDirectory(prefix=filename, dir =os.path.abspath( '.' ))įor number, sizes in enumerate (parts_generator(size)): optimization of the backend and the return of static filesĪsync def process ( url ): filename = os.path.basename(urlparse(url).path).Even large site pages load quickly (the first sign of artificially low speed).You know in advance that your bandwidth is higher than the download speed.The utility developed by me and laid out below - works only if: These values are not taken by chance, for such a download, initially I used exclusively 4G Internet. Although our bandwidth allows us to transfer up to 16 Mbps (2 MB per second) and it will take 512 seconds (8 minutes 32 seconds). Based on these data, we conclude that the download speed will be at least 8192 seconds (2 hours 16 minutes 32 seconds). #7 Waterloo Canada, Canada And Central AmericaĪbout often, some admins set limits on the speed of downloading files, this reduces the load on the network, but at the same time it is very annoying for users, especially when you need to download a large file (from 1 GB), and the speed fluctuates around 1 megabit per second (125 kilobytes per second).#20- 3 Best Ways To Import JSON To Google Sheets.
