That depends on how concurrent boot is, and how fast your CPU and memory are. It may be true on a Celeron, but maybe not on a ThreadRipper.
Furthermore, if you look at the performance testing, the sequential read performance was almost always better with zstd than with lz4, in ZFS; and the zstd-fast mode was about as fast as the lz4 mode in sequential writes. This may be a matter of their specific integration of lz4, but nonetheless it pays to look at the actual numbers before drawing conclusions.
