zstd compression retrio is a bit wired #6270
Comments
already have a local update to zstd 1.5.6 😄 |
@leonpano2006 what results do you expect? what is abnormal in the results? I can confirm that zstd is built with threading support for all CUP modeles (at least zstd binary links to libpthread shared library). |
Compression ratio should be like from low to high |
@leonpano2006 I don't think this is an issue with zstd in synocli-file. I have a debian 12 system with 4 core
|
Then it could be issue with zstd upstream? Maybe zstd in synocli-file can use pho build(but this is other thing) |
@leonpano2006 it looks like an issue that is fixed with zstd 1.5.6 On a DS-918+ I got the following results: zstd 1.5.5
zstd 1.5.6
|
Is this a new Bug?
