    Running multiple tasks at the same time can cause a significant drop in performance. To optimize CPU speed, it’s important to prioritize and minimize the number of tasks that run simultaneously. This way, the board can devote more resources to each task and improve overall performance.

    – Use efficient algorithms and data structures
    The choice of algorithms and data structures can significantly affect CPU performance. When developing your code, consider using efficient algorithms and data structures that are optimized for speed. For example, using arrays instead of linked lists can significantly improve performance.

    – Avoid blocking code
    Blocking code, also known as busy waiting, is code that waits for a specific event to occur before continuing. This type of code can significantly slow down your board’s performance. To avoid this, use non-blocking code or interrupt-based code whenever possible.

    Best Practices for Optimizing CPU Speed
    In addition to the tips mentioned above, following best practices can help you optimize CPU speed on your Arduino board:

    – Use libraries designed for performance
    There are many libraries available for the Arduino platform that are designed to improve performance. When selecting libraries for your projects, choose those that are known for their performance and efficiency.

    – Avoid dynamic memory allocation
    Dynamic memory allocation, also known as heap allocation, can significantly slow down your board’s performance. Instead, use static memory allocation whenever possible.

    – Enable compiler optimizations
    Compiler optimizations can significantly improve performance by reducing the size of your code and reducing the number of clock cycles required to execute it. Make sure to enable these optimizations when compiling your code.

    Common Issues Affecting CPU Speed and How to Fix Them
    There are a number of common issues that can affect CPU speed on an Arduino board. Here are some of the most common issues and how to fix them:
