Actual version of Zlib-ng is 2.2.3. 2.1.0 is quite old and normally 2.2.3 is done here.

I'm working on this, some progress with -march=native and ucd.all.flat.xml from ucd.all.flat.zip:
$ ./lzbench -l

zlib 1.2.11 [1-9]
zlib-ng 2.2.3 [1-9]

$ ./lzbench -ezlib,2,5/zlib-ng,2,5/zstd,2,5 ucd.all.flat.xml

lzbench 1.9 (64-bit Linux)  Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
