Thanks for this. Down the thread I was asking exactly for this. And it seems Zstd is significantly better. We would of course need a wider range of data to really judge this. One thing could be that apple's work started before or in parallel with Zstd and didn't know that this was going to be better. But the problem remains we might end up with a compression algorithm widely used (by virtue of being pushed by apple) while another very similar and better algorithm waiting to come to mainstream. Now if there isn't something special about LZFSE in terms of power usage (beyond faster operation reduces power usage) it would be best if once Zstd is really proved to be solid they phase out LZFSE and start pushing this. Don't really think this would happen. It also seems that Zstd has some dictionary support and so an ever bigger question is whether Zstd can actually replace brotil which probably has a much bigger impact. I really like the idea of Zstd being available everywhere if all the numbers are as good as they seem to be.
