According to this commit description...
...there should be a huge speedup with zstd (compression/decompression) in Kernel 5.16 (some examples):
- SquashFS zstd decompression+read is 15% faster - ZRAM decompression+read is 30% faster - Kernel zstd decompression is 35% faster - Initramfs zstd decompression+build is 5% faster
Let's see if / when this has a positive impact on loading and runtime of the installer. I'm especially interested in low-mem systems using zram.
