With the PR integrated in MGNLRES-319, the following was improved:

• support for glob patterns with good performance
• regex pattern caching to improve regex performance a bit

This still leaves regex pattern performance horrible, as ~ 20,000 pattern matches are performed per call. Projects would need to switch to glob patterns in order to improve performance by dimensions.

PR https://git.magnolia-cms.com/projects/MODULES/repos/resources/pull-requests/91 improves performance by dimensions also for regex expressions, by determining a prefix path where to start matching from.

Existing callers of resfn will profit from this without any code changes.
