libsnappy-dev 1.1.8-1build2 (s390x binary) in ubuntu impish

 Snappy is a compression/decompression library. It does not aim for
 maximum compression, or compatibility with any other compression
 library; instead, it aims for very high speeds and reasonable
 compression.
 .
 For instance, compared to the fastest mode of zlib, Snappy
 is an order of magnitude faster for most inputs, but the resulting
 compressed files are anywhere from 20% to 100% bigger. On a single core
 of a Core i7 processor in 64-bit mode, Snappy compresses at about 250
 MB/sec or more and decompresses at about 500 MB/sec or more.
 .
 This package contains the development files required to build programs
 against Snappy.
