@thomask77 @gsuberland Yes, saves a bit of time, but the decompression uses lots of energy.
Not the right tradeoff for my application (where total energy is king, not time).
SD cards are fast -- best option would probably be to write a home-grown mini bootloader and read an uncompressed kernel at full 50+ MByte/s.

@manawyrm @thomask77 @gsuberland I see you’ve benchmarked gzip‘d kernel and intitramfs but zstd is optimized for fast decompression, so it can be a lot faster, and I wonder if it still uses more energy (and which compression setting is optimal) especially if the video core loads the kernel and that step is slow
