The speed is on compressed stream, mean the hdd. The most over-head of small packet (3Bytes) is drop by high compression with zlib/gzip for the big packet.Ī quick benchmark on ARM64 (odroid, Cortex A53), on kernel Image (12MB), use default compression level (-6) because no way to configure the compression level of btrfs It's transferred size/raw size (lower is better) The socket is always used as full duplex, then it's compression + decompression memory. Pxz default level 6 compression had 9.45MB/s compression speed and 70.43MB/s decompression speed with compression ratio 4. time xz -e -1 linux-3.3.tar du -ksh linux-3.3.tar* ls -l linux-3.3.tar* read PAUSe time unxz linux-3.3.tar* For xz compression, multithreaded xz via pxz was fastest.Its lowest compression is as fast as gzip with better compression and its highest compression level is better than bzip2. It supports to variants of the LZMA algorithm, one really fast and one normal used by all compression levels except 0. time xz -1 linux-3.3.tar du -ksh linux-3.3.tar* ls -l linux-3.3.tar* read PAUSe time unxz linux-3.3.tar* lzip is a lossless data compression program which can be used with tar for compressing archives.time lzma -e -1 linux-3.3.tar du -ksh linux-3.3.tar* ls -l linux-3.3.tar* read PAUSe time unlzma linux-3.3.tar* lzip is a free, command-line tool for the compression of data it employs the LempelZivMarkov chain algorithm (LZMA) with a user interface that is familiar to users of usual Unix compression tools, such as gzip and bzip2.time lzma -1 linux-3.3.tar du -ksh linux-3.3.tar* ls -l linux-3.3.tar* read PAUSe time unlzma linux-3.3.tar*.
