Fixes [#2880]
Added the ability to precache requests concurrently. It looks like this used to be a feature in [#2528], but was removed because it had no limits to the number of concurrent connections, resulting in a lack of resources for large sites with hundreds of assets.
This feature is opt-in, and should be non-breaking. Though it looks like this ticket is part of the V7 milestone. It may be possible to just bump a minor version for this.
Let me know if there's anything I missed that you'd like to see. One thing that might be interesting in the future is a dynamic concurrent request feature, where the lack of HTTP/2+ support or browser resource errors results in the throttling of the batch sizes.

any chance that this open PR gets more attention? Its still an issue on larger SPAs where the reload takes minutes of time until reloading is possible.

@westonruter I would love to hear if there is any chance to get this released otherwise because it is still a major issue for users waiting for the files being pre-cached

@dohomi Sorry, so far I've been focused on getting outdated dependencies updated. I haven't had time to work on new features.

No problem I understand you guys have other priorities. I migrated to https://serwist.pages.dev/ just in case other people also struggle with long delays of precaching. Thanks for the heads up
