Lower throughput at very high levels of SYN flood. A more obvious symptom is an "Attack Detected" log message.
CPS degrades 5-13%, depending on platform.
This degradation occurs only under high rate of new TCP connection creation, typically when CPU usage is greater than 60%.
Change device DoS detection threshold from default to infinite.
Change in default DoS attack detection threshold can degrade L4 performance
