Somebody has compared te python-zlib-ng bindings with the python-isal bindings for performance. ISA-L is the better compessor/decompressor but zlib-ng seems to be faster at performing adler32 and crc32 checksums. zlib-ng/zlib-ng#1478

Since checksum calculation is a significant part of compression/decompression this might be an interesting opportunity to further speed up ISA-L by looking at the zlib-ng implementation.
