Should work with incremental build and use cache to speed up.

It's not working with --incremental build and I wish if it speeds up by using cache or something?

It works with --incremental build but don't speed up and use this feature

Thanks for the suggestion. The gem now includes performance optimizations including:

1. Object caching: Compressor instances are cached and reused
2. Thread-safe operations: Safe for concurrent builds
3. Smart validation: Minimal overhead validation

For incremental builds, the minification still needs to process changed files. However, unchanged files shouldn't be reprocessed by Jekyll's incremental build system.

To use with incremental builds:

JEKYLL_ENV=production jekyll build --incremental

The latest version (v0.2.2) includes performance improvements that should help with build times. The gem respects Jekyll's incremental build decisions and only processes files that Jekyll marks for regeneration.
