ging-dev Thank you for all the feedback @ging-dev.
The latest 1.38 version seems to be stable. To decrease RAM after indexing large /vendor/ folder, I would recommend (for now) closing and re-opening the workspace, although, we'll be working on it in the upcoming updates.
For comparison, plain new Laravel 10 consumes about 69 - 80 MB of RAM, latest Drupal is about 480MB. We'll be working on it constantly.
