similar VMs, allowing for higher VM density on a single host. This is particularly beneficial for scenarios
where many VMs run similar operating systems or applications. By reducing overall memory usage, KSM can improve
system performance and allow for more efficient resource utilization.

<strong>Why it's important:</strong> The CPU governor controls how the processor scales its frequency based on system load. For virtualization environments, setting the governor to 'performance' ensures that the CPU always runs at its maximum frequency, providing consistent performance for VMs. This is crucial for workloads that require predictable and high CPU performance.
