Cisco Cisco IOS Software Release 12.2(27)SBC

The Turbo Access Control List (ACL) Scalability Enhancements feature introduced in Cisco IOS 
Release 12.2(31)SB2 improves overall performance on the Cisco 7304 router using a Network Services 
Engine (NSE) by allowing Turbo ACLs to be processed in PXF using less memory, thereby allowing 
more traffic traversing the Cisco 7304 router using an NSE to be PXF-accelerated. This feature also 
introduces user-configuration options that allow users to define the amount of memory used for Turbo 
ACL purposes in the Route Processor (RP) processing path.
