From reading the
zune-inflatesource (which is in-turn based on libdeflate), I learned about a far faster way to build deflate tables. This is an in-progress implementation to switch over to that algorithm. Right now, it doesn't work with the multi-literal decoding optimization we were using, but I think that can be added.Preliminary results show ~6% average speedups on end-to-end PNG decoding and on the order of 20-25% speedups for small images
