Simulating web page loading performance

Determining the load time for a web page in any specific environment can be challenging and slow owing to the diversity of devices and network types. This disclosure provides techniques to estimate the loading time of a web page in a given environment via simulation of a dependency graph constructed by tracking the page loading process in any available environment. The simulated traversal activates a node only when all of its dependencies in the graph have completed. The time taken for node completion in the simulation is varied depending on the corresponding estimate for the target environment in which the web page would be loaded
