Descriptions

The main reason for implementing zero-copy output in the Dubbo Triple protocol is to significantly improve performance: it reduces multiple memory copies, lowers CPU and memory usage, and lessens GC pressure, resulting in lower latency and higher throughput for service communication—making it ideal for high-concurrency and large-scale distributed systems.
