Performance improvements?

Hi all, had a read through the documentation and struggling to see any potential caching going on? As far as I understand it, Juice will go around reading in the contents of files and inlining them into the string. Could some caching be implemented in the app to prevent recurring reads of the same files?

If this isn't an option, are there any tips for performance tuning that you would recommend?

The issue names no implementation files, tests, or entry points. Start by reviewing the documentation on file inlining and tracing repeated file reads in the JavaScript implementation; establish a reproducible performance baseline before deciding whether caching or tuning guidance is appropriate. Done requires an agreed scope and measurable performance improvement or documented recommendations.
