> Zstandard is faster and compresses better. However, keep in mind that zstd also needs much more memory. IIRC, it uses by default 8 megabytes as its buffer size (and can be configured to use many times more than that), while zlib uses at most 32 kilobytes, allowing it to run even on small 16-bit processors.
