Review Comment:
In `ConcurrentHashMap`, although the order of insertion operations is
uncertain, which leads to test failure, it ensures the thread safety of
insertion operations. Multiple threads can perform insert operations
simultaneously without causing data inconsistency or corruption. It still has a
55% improvement.
