Description

I'm submitting a feature request

Current behavior:

Currently all outputs are stored into a single cache directory. On large projects and certain hardware this might have a negative impact on performances.

Expected/desired behavior:

Something that might remedy the situation is to write into subfolders that contain the first two characters of the key used for storing and use these for reading the cached output.

Contributor guide

Research direction
Explore the existing cache implementation in babel loader to understand how cache key is computed. Modify the cache storage logic to use the first two characters of the key as a subdirectory when writing and reading cache files. Ensure backward compatibility and test with existing cache files.
