Predictive prefetching to improve parallelization of document generation subtasks

A computer-implemented method for dynamically generating documents so as to reduce document generation times, the method comprising:

• for at least one document generation task, monitoring performance of the document generation task over time, and based on said monitoring, generating a mapping reflective of how frequently specific data retrieval subtasks are performed as part of the document generation task;
• receiving a document request that corresponds to the document generation task;
• in response to receiving the document request, using at least said mapping to select one or more data retrieval subtasks to perform preemptively;
• and
• preemptively performing the one or more data retrieval subtasks such that data that may, but will not necessarily, be used to generate the requested document is predictively prefetched based on a prediction that such data will be used to generate the requested document.

A server system programmed to dynamically generate web pages according to a method that comprises:

• for at least one document generation task, monitoring performance of the document generation task over time, and based on said monitoring, generating a mapping reflective of how frequently specific data retrieval subtasks are performed as part of the document generation task;
• receiving a document request that corresponds to the document generation task;
• in response to receiving the document request, using at least said mapping to select one or more data retrieval subtasks to perform preemptively;
• and
• preemptively performing the one or more data retrieval subtasks such that data that may, but will not necessarily, be used to generate the requested document is predictively prefetched;
• based on a prediction that such data will be used to generate the requested document
• said server system comprising one or more physical servers.
