Answer
Global locking can cause performance bottlenecks.
While Collections.synchronizedMap ensures thread safety by locking the entire map, this can lead to performance bottlenecks in highly concurrent environments. For example, during peak traffic on an e-commerce site, this global locking can slow down operations as only one thread can modify the map at a time.
