Startup performance with large data directory

[eryon]

I have a very large data directory due to using multiple pf2e art compendiums and the jb2a animation pack (total size is ~8 GB). As a result, it takes about 5 minutes for my server to start due to the permission operation. I can't move these packs to a read-only volume because they get updated through Foundry package management.

Is there anything I can do to help this operation complete faster?

Sample startup process, see the timestamps of the last two logs:

Take a look at:

• How to disable user data directory permission changes #153
• How to set CONTAINER_PRESERVE_OWNER for multiple directories. #168

Also, since the v13 release is getting nearer I'll mention that CONTAINER_PRESERVE_OWNER will be deprecated in that release as the container will no longer run as root and have the ability to change ownerships.

I added CONTAINER_PRESERVE_OWNER=/data/Data/modules/jb2a_patreon\|/data/Data/modules/pf2e-tokens-* but it hasn't changed the startup time at all. I appreciate that v13 will change things, so I can live with this until then if there isn't an obvious answer :)
