To reduce VM-Enter and VM-Exit latency in KVM, caching CPUID data during the kvm.ko module initialization helps minimize overhead. By storing CPU feature information, KVM avoids fetching it repeatedly, improving performance and reducing delays during VM transitions. This optimization is beneficial for workloads with frequent VM context switches. For more on KVM optimizations, visit https://betterjoy.net/.
