Best way to mass generate conversions ?

[ghost]

Hi guys.

I'm working on a project where users can upload images to a gallery.

I currently use this on my model.

$this->addMediaConversion('responsive')
            ->format(Manipulations::FORMAT_WEBP)
            ->performOnCollections('gallery')
            ->withResponsiveImages()
            ->queued();

This will generate responsive images ( extra 9 images per image ).

Now this takes roughly 10-20 seconds for every image to generate on my basic server.

Now lets say an user is uploading 100 images to the gallery. This means the webrequest would take 30min+ to complete. Because for every image it uploads, it is instantly creating the responsive images as well, thus adding a massive delay.

Is there a way to first upload all 100 original images ( which only takes less then a minute ) and then add a Job or background worker to generate all the responsive images in the background.

That way the user can close his browser after uploading the original images, which will upload very fast and the responsve images will keep generating.

I have no idea what the best way is to do this or to achieve this.

Any of you guys have implemented something like this or know how to do ?
