I did test with my sample data and compared zstd with deflate. zstd's compress ratio is lower a little bit but compression speed is much faster 3 times more and decompress speed is too 2 times more. With different data, it is different but overall, zstd would be better for speed at the cost of a little lower compress ratio(about 5%) so I believe it's worth to replace deflate.
Thanks for the patch, Sergey.
