Yes, everyone tunes their compression settings. /s It's a generalized statement of 'good enough'.

  Even untuned, for every single workload I’ve tried I see more than 2x improvement in speed. Usually 5x to 10x

    This has been my experience too, I didn't even know that gzip could be tuned to be faster than zstd.

      I doubt it can be, unless your data is too small to matter or you’re doing something wrong.

Not actually true if gzip refers to libdeflate[1] or isa-l[2] instead of zlib. Does seem sus here, though,—I couldn’t quickly find which decompression code is used in zboot, but I’d expect it to be closer to zlib. Perhaps their implementation of Zstandard is simpler than the reference one?
