Explanation

High dataplane CPU utilization is often related to the processing power required for handling decryption tasks. Decrypting traffic (e.g., SSL or TLS traffic) consumes significant CPU resources because the firewall needs to inspect and decrypt encrypted traffic to apply security policies. Reducing the amount of decrypted traffic can help lower the load on the dataplane CPU.
