When running HTTP/2 requests with all IPS signatures and compliance checks enabled, 100% TMM CPU utilization peaks occur.
HTTP/2 traffic slowdown occurs, which impacts performance.
-- Virtual server with an IPS and HTTP2 profile -- HTTP2 traffic
To help optimize CPU utilization, enable only the necessary IPS signatures and compliance checks based on specific requirements, rather than activating all available options. While this targeted approach reduces the system’s processing load and maintains essential protections, it may not completely eliminate CPU usage spikes under high traffic or intensive processing demands.
