Reducing latency in rendering of content

A computer-implemented method comprising:

• receiving an item of modified content, the item of modified content corresponding to an item of original content, the item of modified content including an extraction marker, the extraction marker indicating that an item of resource intensive content has been extracted from the item of original content;
• determining whether to retrieve the extracted item of resource intensive content based on one or more of a globally unique identifier (GUID) identifying the extracted item of resource intensive content, a size or dimension of the extracted item of resource intensive content, whether the extracted item of resource intensive content will be visible if displayed on a display screen, and an analytic metric associated with the extracted item of resource intensive content;
• and
• responsive to a determination to retrieve the extracted item of resource intensive content:
• retrieving the extracted item of resource intensive content;
• and
• inserting the retrieved extracted item of resource intensive content in a location within the item of modified content in which the extraction marker is located.

A computer program product including one or more non-transitory machine readable mediums encoded with instructions that when executed by one or more processors cause a process to be carried out to automatically extract an item of resource intensive content from an item of original content, the process comprising:

• identifying an item of resource intensive content included in an item of original content;
• determining whether the identified item of resource intensive content satisfies a first criteria;
• and
• responsive to a determination that the identified item of resource intensive content satisfies the first criteria:
• creating an extraction marker indicating that the identified item of resource intensive content is to be extracted from a location within the item of original content;
• extracting the identified item of resource intensive content indicated by the extraction marker from the location within the item of original content;
• inserting the extraction marker at the location within the item of original content from which the identified item of resource intensive content indicated by the extraction marker was extracted to create an item of modified content, the item of modified content corresponding to the item of original content, the extraction marker further indicating that the identified item of resource intensive content has been extracted from the item of original content;
• and
• saving the item of modified content and the identified item of resource intensive content as separate items in a content repository.
