Lzrw1 compress
WebThe LZ4 algorithms aims to provide a good trade-off between speed and compression ratio. Typically, it has a smaller (i.e., worse) compression ratio than the similar LZO algorithm, which in turn is worse than algorithms like DEFLATE. However, LZ4 compression speed is similar to LZO and several times faster than DEFLATE, while decompression ... WebThe LZRW1 algorithm was the first of a series of high-speed "LZRW" text compression algorithms created from 1990 to 1992. The root name "LZRW" stands for "Lempel-Ziv …

WebLempel–Ziv Ross Williams refers to variants of the LZ77 lossless data compression algorithms with an emphasis on improving compression speed through the use of hash tables and other techniques. This family was explored by Ross Williams, who published a series of algorithms beginning with LZRW1 in 1991. The variants are: The LZJB …
WebOct 21, 2015 · If you had an algorithm that could compress your data by 25% for an effective 125mb/s write speed, you would have 24 cycles per byte to run it in and it would basically be free because the CPU wouldn't be doing anything else anyway while waiting for the disk to churn. 24 cycles per byte = 3072 cycles per 128-byte cache line, easily achieved. graph f x 1/2x 2WebFeatures: LZRW1/KH compression/decompression classes for byte arrays, streams or files.
