Speed up the installer by pre-building a cache of Recipe objects in a serialized format

Not a definitive tag, but I believe this should block a stable release. The status quo is a serious performance problem that will be detrimental to getting new folks started on Drupal CMS.

Assigning to @tim.plunkett for review and final approval, I think.

This is not really a Pam thing because it does not change the outward UX or behavior of the installer in any way; it's a purely technical improvement that boosts the speed. Seems unlikely that Pam would frown on it. But this kind of technical change should probably be reviewed by the tech lead. :)

Fantastic work!

Mad science pays off sometimes. Merged into 0.x!

Automatically closed - issue fixed for 2 weeks with no activity.

This sounds great, thanks! But which times are we talking about ... like, how many seconds did the old and slower method take, and how fast did it get? Because with 📌 Add the ability to install multiple modules and only do a single container rebuild to ModuleInstaller Active and 📌 Remove the automatic cron run from the installer Needs work , Drupal 11.2-dev installs in only 5 seconds:

The Drupal CMS UI in the browser install takes around 40 seconds, when I tried a few days ago, both with 11.1 and 11.2, which I found strange, since it seemed like the improvements in the two issues about Container and Cron didn't take effect ... Perhaps you can check if you see any time differences between 11.1 and 11.2 in Drupal CMS UI installer? Thanks!
