pgzip

pgzip is a Python library that provides a multi-threading implementation of the standard `gzip` module. It aims to be a drop-in replacement, offering significant performance improvements for compression and decompression of large files by leveraging parallel processing. It achieves this by utilizing block indexing within the gzip file's `FEXTRA` field, ensuring compatibility with standard gzip tools. The library is actively maintained, with a recent major release (0.4.0) indicating ongoing development and support for newer Python versions.
