It is necessary to determine if the high CPU utilization is due to the device being oversubscribed or due to another issue. The device can experience high CPU when the platform approaches the maximum VPN throughput it can handle. CPU utilization will increase as more encrypted or decrypted traffic handled by the device. Problem Symptoms and Identification High CPU UtilizationĬPU utilization directly impacts performance for VPN users. See the following to determine how to identify these issues and mitigation strategies to address them. With significantly increased RAVPN usage, An圜onnect users may experience performance issues.
