There’s an optimized data-directory-specific catalog and config loader plugin developed under geoserver-cloud’s code base that we’d like to contribute upstream as a community module.

Its goal is to improve the startup time of GeoServer when configured with a data directory that has thousands of layers, stores, etc., and config objects such as workspace services and settings.

On my laptop’s SSD, running off a cold disk cache, for a data-dir with 100K layers over 100 workspaces, the performance improvement is ~8.5 seconds instead of ~44.5 seconds, with 2.23.1 as a baseline.

But the most important difference is when you need to load the data dir from a shared drive, especially NFS, where it regularly takes over 40 minutes, and with this plugin around 4 minutes.
