> Gathered from multiple workload runs, the presented data underscores a noteworthy enhancement in performance. The adoption of ByteBuffer for *reading operations* exhibited a remarkable improvement of approximately *64.83%* when compared to traditional disk-based reading. Similarly, the implementation of ByteBuffer for *write operations* yielded a substantial efficiency gain of about {*}60.75%{*}. These findings underscore the consistent and substantial advantages of integrating ByteBuffer across a range of workload scenarios.
