 Nmon for Splunk App intensively uses data model acceleration in almost every user interfaces, reports and dashboards.
 The application provides multiple data models that have the acceleration activated by default using "All time" as the time range limit.
 
-Because of the richness of Nmon monitors, and with large deployments, accelerated data model offers an improved user experience.
-Note that some minor scheduled reports that keep users informed of the application activity in home page uses standard acceleration.
+Splunk Accelerated data models provide a great and performer user experience.
