2.3. Memory Performance for Security

This document describes the memory usage for Security Plugins in release 6.1.0. Since most of the memory performance for security is the same as described in the Memory Performance section for Connext DDS Professional, we focus here only on the differences in heap usage when using different levels of security. Compare these results with Heap Usage of Connext DDS Entities in the Connext DDS Professional section.

Heap Usage

The following table shows the differences between the base case (not using security) and different levels of security enabled:

Entity/Size (Bytes)	Not Using Security Libraries	Authentication Only	RTPS Encrypt	RTPS Sign with Original Auth	Data Encrypt	RTPS Sign	Submessage Encrypt with Original Auth	Data Encrypt	RTPS Sign	Submessage Encrypt	RTPS Sign
