According to fastjson2's official benchmark [1], fastjson2 is about 4x faster
than jackson on JDK17 and 3x faster on JDK8. Similar results are observed in
our production environment. In addition, UTF8 bytes <-> String conversion is
much faster on JDK17 with vectorized algorithms [2][3], so even
I notice you mean especially in jdk 17+, is there any more details about it?
right now we be using flink 1.14 with jdk 8, so I do have a plan to do a
whole upgradation(means to update to flink 2.1 with jdk 24/25/graalvm 24).
