Dynamic file segmentation and connection reuse and their impact on download performance

Internet Download Manager has optimized file download logic. IDMan divides downloaded file on file segments dynamically, unlike other download accelerators that divide downloaded file in segments one time before download process starts. Dynamic segmentation gives significant download performance improvement. When file download starts, it's unclear how many connections may be opened. When new connection becomes available IDMan finds the largest segment to download and divide it in half. Thus new connection starts downloading file from the half of the largest file segment. IDMan minimizes the time needed for negotiations with server and keeps all connections busy.

On a progress bar pink lines show start positions, blue - downloaded segments, white - the segments to download.

Once a connection has downloaded a segment (when blue bar comes to a pink line) and if the next connection has not started to downloaded its segment yet, IDman reassignes the segment to the first connection. If the next connection has started to downloaded its segment, first connection helps other slowly working connections by dividing the largest segment in half. IDMan won't divide the segment only when its size is too small.

When all connections have finished downloading segments, IDMan will assemble segments into one file. IDMan saves all file positions several times per minute. Thus when you stop/pause downloading or even after unexpected power shutoff, IDMan will resume the download and assemble the file correctly.

Benchmarking shows significant download speed increase especially for shared Internet connections. Bar charts show download time in seconds for the same file that has been downloaded with different applications and from different Internet Connections.
In these tests conducted in the independent laboratory, Internet Download Manager shows clear lead over its competitors.
