Increased loading time when the ‘Rich workspace’ option is activated.

[jfpbc]

Describe the bug
I have 5000 group folders configured with tag and ACL, when the ‘Rich workspaces’ option is activated it takes about 3 minutes to load the file app. Once the option is deactivated ( occ config:app:set text workspace_available --value=0 ) it takes 14 seconds.

Server details:

• Nextcloud version: 29.0.5
• PHP Version: 8.3
• Database: Postgres 16

Client details:

• OS: Windows / Ubuntu
• Browser: Firefox Chrome

After further research, the Webdav response contains a ‘ <nc:rich-workspace /> <nc:rich-workspace-file /> ’ field for each sub-folder which is not necessary.
