Though you have benchmarked a wrong thing. It’s decompression time
that matters here, not compression. The image is compressed to make it
load faster during boot and that’s the important metric here.
I did my own bench

I benchmarked it on my mkinitcpio image, and zstd with mkinitcpio's
default compression level 19 (standard COMPRESSION_
What about when you have an nvme disc with relatively slow boot up times?

It's a balance between CPU usage and disk IO. cat requires more data to
be read from disk, zstd requir

I don't think you'll notice much difference with either one.

I wonder about this, too. Even the zstd guys don't claim that:

According to their benchmarks lz4 decompression is way faster. That'
