Hashtable is synchronized and less efficient compared to modern alternatives like ConcurrentHashMap.
Hashtable synchronizes all method calls, which can lead to unnecessary overhead in performance. ConcurrentHashMap is a better choice for concurrent access as it provides thread safety with better performance due to segmented locking. This makes it more suitable for modern multi-threaded applications.
