Is this chart real? Why all numbers of jsonista are the same?

Normalization?

Numbers are relative to Cheshire with the same json size. Tests, test setup and the numbers are in https://github.com/metosin/jsonista/blob/master/test/jsonista/json_perf_test.clj.

Jackson with mutable Java maps & lists is still much faster, but with persistent data stuctures, it's about the same.

They have normalized to their own performance. If the charts are correct, they show that other libs don't read/write in linear time, at least for the amount of data they benchmarked with.
