Introduction to Aria2

Aria2 is a multi-platform lightweight command line download tool that supports multiple protocols and sources such as HTTP, FTP, and BitTorrent. Aria2 can download resources from multiple sources and protocols, making the most of your bandwidth. Aria2 has a very small resource footprint. When the disk cache is turned off, the physical memory footprint is usually 4M (in the case of normal HTTP/FTP downloads). When BitTorrent downloads are 2.8M/S per second, the CPU occupancy rate is approximately 6%. Aria2 supports JSON-RPC and XML-RPC interface remote calls.

Many people may have used Internet Download Manager in Windows, which is a very useful multi-threaded download tool. Aria2 is similar to IDM. It can not only download through multi-threads, but also download from multiple sources. Simply put, it downloads a file from multiple mirror servers at the same time. Aria2 also supports the BT protocol, which makes up for the pain point of IDM that only supports HTTP and FTP.
