How to use accelerated download speed?

[e-t-l]

Is there a particular setting required in order to split files and download them faster? Does it only work for certain types of files or in certain scenarios? I downloaded some large test files both with and without TDM, and the DL speed was identical.

I also did the same test with large files and the time it took to download was the same with and without the extension, I have the same doubt if this extension requires any additional configuration.

It clearly seems that this extension is now officially placebo. I, like you two, also did that test; the download speed is completely the same and the download itself is managed by Firefox the default download manager.
