IPS Algorithms
There is a new algorithms for IPS, “super” mode, that improves performance for FortiGate units with more than 4GB of memory. Improvements have also been made for “low” mode, which is more efficient for FortiGate units with low memory.
The algorithm used for IPS can be changed from the CLI, using the following command:
config ips global
set algorithm {engine-pick | high | low | super}
