## IMPORTANT WARNINGS

Pre-compressed input typically compresses in excess of 2GiB/s per core,
so performance impact should be minimal even if precompressed data is re-compressed.
Decompressing incompressible data has no significant performance impact.

Below is a list of common files and content-types which are typically not suitable for compression.

 | `gz`  | (GZIP)      |
 | `bz2` | (BZIP2)     |

        There is always *some* alternative to adding a new feature to Guava, even if it's just
        forking Guava yourself.


        We want to see that new features have some significant advantage over the alternatives.
        These advantages can take
        [many forms](https://github.com/google/guava/wiki/PhilosophyExplained#utility), but taking

## 📊 Performance Metrics

CoreLib 0.7.0 includes significant performance improvements through Java 21 optimizations:

- **5-15% faster** type conversions with pattern matching and switch expressions
- **Reduced memory allocation** in collection operations and bean copying
