Distributing Explicit Web Proxy Traffic to Multiple CPU Cores
To improve explicit web proxy performance, FortiOS 5.2 distributes explicit web proxy processing to multiple CPU cores. By default web proxy traffic is handled by half of the CPU cores in a FortiGate unit, so if your FortiGate unit has 4 CPU cores, by default two will be used for explicit web proxy traffic. You can increase or decrease the number of CPU cores that are used in the CLI.
config system global
set wad-worker-count <number>
end
The value for <number> can be anything between 1 and the total number of CPU cores in your FortiGate unit. The default value for <number> is half the number of CPU cores in your FortiGate unit.
