Elke verbinding tegelijk. Verdergaan waar het stopte.

Geen verbinding blijft inactief

GDM opens 8 connections by default, and you can set anything from 1 to 32 in Options → Connection. When a connection finishes its part, it takes over half of the largest part still left, so the work is shared out again and again until the file is done. A connection that falls far behind the others is dropped and opened again.

Het voortgangsvenster toont dit terwijl het gebeurt: een balk van het hele bestand met de start en voortgang van elke verbinding, en een tabel met wat elke verbinding op dit moment doet.

Gemeten, niet geclaimd

On the same PC and the same test server, GDM fetched a 1 GiB file in 1.0 s against IDM 6.42's 5.5 s, and a 256 KiB file in 0.03 s against 3.1 s: the medians of alternating runs. The benchmark page has every run, the method and the raw data.

More connections help only where a server sends each one at a limited speed. Most servers allow a few connections per address, and GDM notices when one says no: it stops asking that server for more and lists what it learned under Exceptions in Options → Connection. You can set a number for a server yourself there too.

Meer dan 32, als u dat wilt

Meer dan 32 verbindingen toestaan in Opties → Verbinding verhoogt de limiet tot 128 per download, ook voor serveruitzonderingen. De opdrachtregeloptie -c accepteert 1 tot 128.

Hervatten dat een crash overleeft

GDM saves how far each part has got as it goes. A download picks up where it stopped after you pause it, after the connection drops, or after Windows or GDM itself crashes. A connection that fails is retried on its own, and the table shows Retrying with the reason.

Before it continues, GDM checks that the file on the server is still the same one, so a changed file never gets stitched onto an old half. When a server can't send a file in parts, the progress window says Resume capability: No before you rely on it.

Rechtstreeks naar schijf

Each connection writes directly into the file's place on disk, in a part file next to the final one. There is no temporary folder and no joining step at the end: when the last part arrives, GDM checks the size and renames the file.
