Sharing a read-only database between multiple BaseX instances

Hello,
I have a collection which is read-only. This collection is used as source for multiple XQuery update operations, operations which do not modify this read-only collection.
For performance questions, I want to parallelize my XQuery operations. So I want to have multiple BaseX instances - say 8 - sharing exactly the same read-only collection, each instance performing a XQuery update on a small amount of data
As this collection is read-only, may I physically copy files (after import) from an instance to another, if instances are on different hosts, and may I symlink collection files from an instance to another if instances are on the same hosts ?
When I import data in the "read-only" collection to initialize it, only one instance is started...
Best,
Christophe
