Optimization Overview
non-application-accelerated traffic, the former is limited; the latter is not. If you have 50 Mbps of
application-accelerated traffic, the ACE can still deliver up to 1.9 Gbps throughput for the
non-application-accelerated traffic.
Optimization Overview
The application acceleration functions of the ACE appliance apply several optimization technologies to
accelerate application performance. This functionality enables enterprises to optimize network
performance and improve access to critical business information.
The ACE appliance provides the following application acceleration and optimization functionality:
• Delta optimization eliminates redundant traffic on the network by computing and transmitting only
the changes that occur in a Web page between successive downloads of the same page or similar
pages.
• FlashForward object acceleration technology eliminates network delays associated with embedded
cacheable Web objects such as images, style sheets, and JavaScript files by placing the
responsibility for validating object freshness on the ACE appliance, rather than on the client,
making the client more efficient.
• Just-in-time object acceleration enables acceleration of non-cacheable embedded objects, resulting
in improved application response time by eliminating the need for clients to download these objects
on each request.
• Adaptive dynamic caching accelerates enterprise application performance and improves server
system scalability by enabling the ACE appliance itself to fulfill requests for dynamic content,
which offloads application servers and databases.
Refer to Configuring Application Acceleration and Optimization, page 13-1 or the Application
Acceleration and Optimization Guide, Cisco ACE 4700 Series Application Control Engine Appliance for
more information about application acceleration and optimization.

Optimization Traffic Policies and Typical Configuration
Flow
To define the different optimization and application acceleration functions that you want the ACE to
perform, you must configure at least one each of the following:
• HTTP optimization action list—This action list specifies the actions that the ACE is to perform for
application acceleration and optimization. You can configure action lists when configuring a virtual
server, or as a separate procedure. See:
– Configuring Application Acceleration and Optimization, page 13-1
– Configuring an HTTP Optimization Action List, page 13-3.
