according to llm decompressing data and reading it from disk is faster than keeping gzipped data in ram and decompressing it:
>data throughput for gzip decompression ... it typically ranges from 200-500 MB/s.
>Typical read speed for a single binary file from an NVMe SSD is around
3-4 GB/s.
however gzip still helps delivering compressed data through network and storing it if disk space is limited.
