Method embodiments are disclosed for characterizing network latency for a component of a webpage provided by an application server device, using boxcarring of action requests. The method comprises measuring the network latency for a component provided by an application server device. A latency category is established based on the network latency. An action request of a user occurring within a queue wait time is associated with the latency category. The action request of the user associated with the latency category is enqueued into an enqueued action request, which is batched in a boxcar to create a batched action request. The batched action request is dispatched in the boxcar to the application server device. The queue wait time is adapted based on an updated network latency and a transmission status of the action request of the user and the batched action request. System and computer program product embodiments are also disclosed.

Characterization of network latency using boxcarring of action requests from component-driven cloud applications

Performance of web pages and mobile device applications with multiple components rendered on a user device is dynamically speeded up, including dynamically measuring network communication latency, adjusting inter-boxcar intervals used to dispatch batches of action requests from the user device to a production server, and dispatching boxcarred requests to the server. Adjustments to the boxcar intervals are based on the dynamically measured network communication latency and a number of connections supported between the user device and the server. The measured network communication latency is calculated as dispatch-to-completed response time minus server processing time and the server processing time is received from the server for a boxcar of completed responses. The system adjusts according to feedback received, as a browser or mobile device changes network connections or the network conditions change, and adapting over time for a particular user. Inter-boxcar intervals are tunable and programmatically changeable, with values learned from experience.

Dynamic adjustment of boxcarring of action requests from component-driven cloud applications

Improved perceived load time for browser and mobile application pages is achieved by adjusting boxcarring of action requests from coupled data consuming applications on the user device, using the priority level of regions and components in component-driven cloud applications. Priority labels differentiate among display regions rendered by the data consuming application and the priority labels further differentiate among components within respective display regions. The middleware application batches the action requests into batches based at least in part on the priority labels, into boxcars segregated by priority label according to a predetermined segregation schedule, and dispatches the boxcars of batched action requests to the server. Performance is also dynamically speeded up, by adjusting inter-boxcar intervals used to dispatch batches of action requests from the user device to a production server, based on the dynamically measured network communication latency between the user device and the server.
