Yeah there’s a difference in techniques used for lossy vs lossless. But my point was that in compression research, runtime performance was much less important than compression performance, that was no different for lossy compression.
- jijji 5y agospeaking of runtime performance if you look at lzma for instance it's horrible on runtime performance but it produces some of the best compression ratio of all of them
- account42 5y agolzma usually decompresses significantly faster than bzip2, which is what it mostly replaced in e.g. package distribution. It also decompresses fast enough that for slow enough connections download + decompression is faster than deflate. Compression is slow though, yes.
