Overall improvement to SSL inspection performance (405224)

The enabling / disabling of proxy cipher / kxp hardware acceleration in CP8/CP9 required restarting of the WAD daemon for the change to take effect; this bug has been repaired.

New CLI commands

The FortiGate will use the ssl-queue-threshold command to determine the maximum queue size of the CP SSL queue. In other words, if the SSL encryption/decryption task queue size is larger than the threshold, the FortiGate will switch to use CPU rather than CP. If less, it will employ CP.

config firewall ssl setting set ssl-queue-threshold <integer>


The integer represents the maximum length of the CP SSL queue. Once the queue is full, the proxy switches cipher functions to the main CPU. The range is 0 – 512 and the default is 32.
