[Qemu-devel] [PATCH v0 3/3] qcow2: add zstd cluster compression

2019-05-28 Thread Denis Plotnikov
zstd significantly reduces cluster compression time. It provides better compression performance maintaining the same level of compression ratio in comparison with zlib, which, by the moment, has been the only compression method available. The performance test results: Test compresses and decompres
