The gist of how I came up with this is, you download the latest 7-Zip SDK, just extract the C# bits (the CS folder). And the results are normalized with AMD K8 cpu in that complex benchmark. Sets multithread mode. Note that the tests of LZMA have big weight in "total" results. multithread gives about 8000KB/s and 100000KB/s. I already use gzip (or xz or 7-zip) compression.” Well, zstd is fast. xz. Lz4. By default when the compression level is not specified, gzip uses -6, bzip2 uses -9 and xz uses -6. I want to compress different files with different sizes in 7Zip application to use its different compression methods. 7-Zip is a multi-threading archiver, especially in de-compression this shows really well.
