| 3.2.9 |  | Turbo ACLs |

| Turbo ACLs were introduced in Cisco IOS Software Release 12.1.5.T and are found only on the 7200, 7500, and other high-end platforms. The turbo ACL feature is designed to process ACLs more efficiently by compiling them into executable code, in order to improve router performance. Using compiled ACLs can greatly reduce the performance impact of long lists.

Use the access-list compiled command for turbo ACLs. An example of an ACL that can be compiled is shown in Figure .

After defining the standard or extended ACL, use the global configuration command to compile it .

The show access-list compiled command shows statistics about the ACL.
