Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 6 : IPS Hardware Acceleration
  
IPS Hardware Acceleration
New CLI commands have been added for configuring IPS hardware acceleration, replacing the previous set hardware-accel-mode command, to provide finer control over the settings. There are now two settings that can be chosen, one for the network processor and one for the content processor.
Network processor acceleration can be disabled or set to enable basic acceleration. Content processor acceleration can be disabled or enabled for either basic or advanced acceleration.
Syntax
config ips global
set np-accel-mode {none | basic}
set cp-accel-mode {none | basic | advanced}
end
