Serialization is a crucial aspect of Java programming, enabling the conversion of complex data structures into a byte stream for storage or transmission. With numerous serialization libraries available, choosing the most efficient and effective one can be daunting. This paper presents a comprehensive comparison of Javryo, a high-performance serialization library, with other popular libraries in Java. Our analysis focuses on key performance indicators, ease of use, and feature sets, providing insights for developers to make informed decisions.
