This result was gotten in ARM architecture, it is not general CPU.
Please see detail document.

I found compression algorithm test in HBase. I don't read detail, but it indicates snnapy algorithm gets best performance.

In fact, most of modern NoSQL storages use snappy. Because it has good performance and good licence(BSD license).

I think it is bit difficult to prove that any one algorithm is best
for all kind of loads.
I think it is necessary to make best efforts in community than I do the best choice with strict test.
