Test and improve method of Real-time performance for OpenPLC

Real-time performance refers to the ability of the operating system to respond to external events in a timely and deterministic manner. In other words, the system can guarantee that a certain task will be completed within a specific time frame. Real-time performance is important in many applications, such as industrial automation, robotics, and telecommunications. In these applications, the system must respond to external events within a specific time frame to ensure that the system operates correctly.
