1983371 - Exploratory bug to measure performance of downloading (artificially) large number of files.

Status: NEW

(Toolkit :: Downloads API, task, P3)

Description

[Mayank Bansal]

Attachment: download many empty files.html

Open testcase
Enter a large number like 5000 in the input box
Click on download button

Profile: Firefox: https://share.firefox.dev/3Jog2TH. The whole browser is completely unresponsive during this period.
Note: The folder i was using for downloads is also backed up using Microsoft OneDrive. Maybe that makes things worse.

Testcase generated using chatgpt. We should also implement a feature that asks user to confirm if the page is trying to download multiple files, effectively creating a DOS.

That's bug 1306334 afaict.

In the profile I see various calls to System APIs after DownloadDone is invoked, for AddToRecentDocs, maybe that could be made async.
I think in the end it boils down to Bug 1714504.

Marking as a Task since there's bugs tracking the issues already.
