MEMORY MANAGEMENT
bzip2 compresses large files in blocks. The block size affects both the
compression ratio achieved, and the amount of memory needed for compression
and decompression.

since that maximises the compression achieved. Compression and decompression
speed are virtually unaffected by block size.
