Lzo compression algorithm lzgtd

The lzo dd_rescue plugin (subsequently referred to as just ddr_lzo which reflects the variable parts of the filename libddr_lzo.so) choses compression or decompression mode automatically if one of the input/output files has an [lt]zo suffix; otherwise you may specify compr[ess] or decom[press] parameters on the command line.

[MS-XCA]: Xpress Compression Algorithm. 5/8/2020; 4 minutes to read; In this article. Specifies the three variants of the Xpress Compression Algorithm: LZ77+Huffman, Plain LZ77, LZNT1, and their respective decompression algorithms. This algorithm efficiently compresses data that contains repeated byte sequences. LZO: Similar to Snappy, LZO (short for Lempel-Ziv-Oberhumer, the trio of computer scientists who came up with the algorithm) provides modest compression ratios, but fast compression and decompression speeds. LZO is licensed under the GNU Public License (GPL). LZO supports splittable compression, which enables the parallel processing of Aug 10, 2017 · Introduction In this document, we describe Intel IPP data compression functions, that implement the LZO (Lempel-Ziv-Oberhumer) compressed data format. This format and algorithm use 64KB compression dictionary and do not require additional memory for decompression. The LZO compression support for Btrfs was developed by Fujitsu and was added since the LZO algorithm is designed to be much faster than gzlib. With the Linux 2.6.38 kernel and later, zlib or lzo compression can be choosed at mount time by passing the respective compression algorithm to the compress argument. Aug 16, 2016 · The clearest takeaway is that LZO compression is the most performant at every scale factor we tested. The LZO — or Lempel-Ziv-Oberhumer — algorithm was designed specifically to optimize for fast decompression, so this result is not too surprising, and helps to validate the idea that we are primarily CPU-bound when COPYing compressed data.

lzop uses the LZO data compression library for compression services. The amount of compression obtained depends on the size of the input and the distribution of common substrings. Typically, text such as source code or English is compressed into 40-50% of the original size, and large files usually compress much better than small ones.

one of main features available is: Compression(zlib and lzo) squashFS is a compressed read-only file system, zlib, xz and lzo compression is supported zram Increase performance by avoiding paging on disk and instead use a compressed block device in RAM, lzo is used for compression There will be more

LZO is not yet included, but pure Java LZF has excellent performance (esp. compression speed), and I assume LZO might fare well too, if there was a driver for it. Another LZ-based algorithm is Snappy by Google, and its native codec is the fastest codec at decompression (and compression is as fast as pure-java LZF compression).
