Performance optimization ideas

• Optimize MessageContext creation (for high-throughput scenarios): On every incoming message, a new, large MessageContext object is created, including numerous function closures (reply, progress, error, etc.). For the vast majority of applications, this is perfectly fine and leads to clean, easy-to-read code. However, in extreme high-throughput environments, the overhead of this object and closure creation for every single message could become a performance bottleneck. A potential optimization could be to use a reusable, per-connection context object that is simply updated with the details of each new message, rather than being recreated from scratch. This is a significant architectural change with trade-offs in complexity and is not a necessary change, but it's something to keep in mind for future performance tuning.
