I assume you wanted to link to TurboBench and not that particular issue, which for some reason also contains a link for some car listing?
Secondly, did you not see my answer to ebiggers under this comment you replied to? Yes, for Silesia, libdeflate is faster, I can confirm, but there are at least two cases for which igzip is faster and one for which igzip is twice as fast. But yes, it heavily depends on the input data.
Edit: I was then wondering why I could not find any igzip benchmarks on the repository's ReadMe and then found https://github.com/powturbo/TurboBench/issues/43 , so I guess this is the one you wanted to link to and the 3 got cut off.
