App Acceleration directly addresses the causes of poor app performance and
acts in real-time to mitigate them, dramatically improving the user experience for
Prisma Access
GlobalProtect and Remote Network users.The primary causes of poor user experience when accessing apps are dynamic content
(content that must be processed for each user individually, on-demand) and network
connectivity issues.
App Acceleration provides you with the following functionality:
Network Acceleration
—When your users access apps, they can experience poor app
performance that is caused by decreased throughput, which could be caused by packet
loss, degraded wireless connectivity, network congestion, and other factors. These
networking issues can adversely affect the employee experience and reduce their
productivity. When the internet was conceived, networks were homogenous and wireless
connectivity was in its infancy. Fundamental protocols like TCP were originally
created for these networks. Today, networks are no longer homogenous and wireless
connectivity creates a highly variable user experience. When users experience
degraded network conditions, TCP can't differentiate if the problem occurred because
of device limitations, network limitations, or physical constraints.
Without requiring any changes to your client configuration or applications, App
Acceleration securely builds an understanding of the:
- Device capability—The type of client endpoint
- Network capability—The type of network
- App Context— The type of app being used
Using its understanding of device, network and application context, App
Acceleration maximizes throughput and adjusts in real-time to account for changing
network conditions.
When compared to direct internet access, App Acceleration offers a marked throughput
improvement for TCP traffic when connecting through
Prisma Access
. You can view throughput improvements from App Acceleration in Prisma SASE
Incidents and Alerts. AI-powered Autonomous DEM (ADEM) integrates with App
Acceleration and provides you with metrics such as the number of applications that
were accelerated and the performance boost gained overall.
Configure App Acceleration
Enable and configure App Acceleration by completing
the following steps.
- (Panorama Managed Deployments Only) Go to andGet Startedwith App Acceleration.
- Go to from the left navigation bar.
The App Acceleration window displays.
- Move the slider to the right to have App Acceleration beEnabled for all Mobile Users—GlobalProtect and Remote Networks.
App Acceleration is now enabled.
- (Optional)Show Advanced Optionsand change the metric testing parameters.
- (Optional) To disable the performance metric testing, deselectAllow tests to collect performance metrics for Mobile Users.Palo Alto Networks recommends that you enable metric collection to view the app performance improvements when using App Acceleration.
- (Optional) To change the percentage of users for which predictive tests are processed from the default of 5%, select another percentage in the drop-down list andConfirmthe changes.
View App Acceleration Metrics in AI-Powered ADEM
By default, synthetic tests are enabled to collect performance metrics and
display them through AI-powered ADEM. These tests take approximately 24 hours to
run for the first time. The tests run through a split tunnel and have no effect
on your security posture.
To view the metrics, Go to and view the ADEM performance metrics in the
Accelerated Applications
and Monitored
Applications
tabs.These tests take approximately 24 hours to run for the first time and you must
have ADEM performance tests enabled to see them.
You view applications in these tabs:
- Accelerated Applications—Provides App Acceleration data that’s aggregated across all applications:
FieldDescriptionPerformance BoostThe overall aggregate of acceleration is computed by dividing acceleration speedup by preacceleration throughput. This metric is derived from ADEM synthetic test data comparing the throughput before acceleration with the throughput after acceleration.Applications AcceleratedThe total number of unique applications that were accelerated.Users AcceleratedThe total number of GlobalProtect and Remote Network mobile users who benefited from App Acceleration.Total Data TransferThe total data transfer across all accelerated apps. The displayed number includes the total number of bytes in and bytes out.
