 * TLS 1.2 support for client and server (but not UWP servers)
 * Extensible communication channels (i.e. In-Memory, TCP, TCP+TLS, WS)
 * Lightweight (only the low level implementation of MQTT, no overhead)
-* Performance optimized (processing ~25.000 messages / second)*
+* Performance optimized (processing ~27.000 messages / second)*
 * Interfaces included for mocking and testing
 * Access to internal trace messages
 * Unit tested (57+ tests)
