Thats what I was thinking. I haven't found any validation or even the rationale behind lzfse's supposed lower power usage. I can think of two things. 1. Apple tried to write a fast and reasonably compressible version of LZ4 thus improving power usage by creating LZFSE since none existed but beaten out handsomely by Zstandard. 2. Following a parent comment, Zstandard might some of the things that are dependent on a highly OoO cpu with lots of caches, extremely good branch predictor that could be significantly slower on an ARM even the apple one despite how good they are. Or they could still be slower but on ARM the gap might not be as big and the decision not as cut and dry as it seems now. Would love to know what the actual case is from someone involved in LZFSE.
