Compression/Decompression rates #53

Closed waitaria closed 5 years ago

waitaria commented 5 years ago

Hello, I had a question regarding the reporting of the rates for the compression and decompression algorithms. Are the rates (given in MB/s) reported for the output or input of the compression? How about the decompression? IE does a decompression speed of 500 MB/s mean that the decompression algorithm outputs 500MB of uncompressed data each second, or does it decompress 500MB of compressed data into, say, 1000MB of raw data each second?

Hi, compression and decompression speed is measured regarding to the size of original/uncompressed data. This sentence is true: decompression speed of 500 MB/s mean that the decompression algorithm outputs 500MB of uncompressed data each second.
