Web page load time prediction and simulation

A computer readable memory storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:

• extracting one or more dependency relationships for each web object in a webpage, each dependency relationship being a relationship between a corresponding web object and an associated descendant web object or an associated ancestor web object;
• ascertaining an original performance metric value associated with a page loading of the webpage;
• modifying original timing information associated with the page loading of the webpage to obtain adjusted timing information;
• simulating an additional page loading of the webpage based on the adjusted timing information and dependency relationships between the web objects in the webpage to estimate a new performance metric value associated with the additional page loading;
• and
• implementing the adjusted timing information for executing a subsequent page loading of the webpage in response to determining that the new performance metric value is less than the original performance metric value.

A computer-implemented method, comprising:

• extracting one or more dependency relationships for each web object in a webpage, each dependency relationship being a relationship between a corresponding web object and an associated descendant web object or an associated ancestor web object;
• ascertaining an original performance metric value associated with a page loading of the webpage;
• modifying original timing information associated with the page loading of the webpage to obtain adjusted timing information;
• simulating an additional page loading of the webpage based on the adjusted timing information and dependency relationships between the web objects in the webpage to estimate a new performance metric value associated with the additional page loading;
• and
• determining whether the adjusted timing information increased or decreased the new performance metric value as compared to the original performance metric value.
