Download speed limit on chunks

[adel-bakhshi]

Hello,
First of all, thank you very much for creating this package and making it available to others for free.
Thank you so much to you and everyone involved in the development of Downloader ❤️.

The issue I'm facing is that when I enable ParallelDownload for the chunks to download simultaneously, it seems like the download speed gets divided among the chunks so that all of them have roughly the same speed.

In such a situation, if the file is divided into 8 parts and 7 parts have been fully downloaded, the eighth part downloads at one-eighth of the main speed (or, if there's a speed limit, at one-eighth of the limit).

I'm not sure if I'm mistaken or if the settings I've configured are causing the problem, but this is what I've observed. Could you please guide me on how to solve this issue?

I found this code and as I was saying the speed is divided by the number of chunks.
Wouldn't it be better to divide this value by the number of active chunks? I remember seeing such a property but I don't know where it is.

This is also happening in this section with the change in maximum speed.

And finally, the maximum speed of reading data from the Stream is set here.

If possible, add a property to the DownloadConfiguration class to set the download speed of the chunks. For example, they should be the same or have no limit.

Hello,
Thank you for opening this issue and providing detailed feedback! You’re absolutely right the MaximumSpeedPerChunk should indeed be adjusted according to the number of active chunks. This is a valid point, and it makes sense to ensure the speed limit is distributed dynamically based on the current download state.

I’ll work on fixing this behavior in the next version of the Downloader. Your feedback is greatly appreciated, and it helps improve the project for everyone.

If you have any additional suggestions or encounter further issues, feel free to share them. Thanks again for your contribution!

Best regards,

Hi @adel-bakhshi
Please test last version 3.3.2.
I fixed this issue. Now, calc the max speed according by active chunks count.
Thank you for feedback.
